Update to 3.2.1: 3.2.1 (2013-05-11) ================== Features added -------------- * The methods ``apply_templates()`` and ``process_children()`` of XSLT extension elements have gained two new boolean options ``elements_only`` and ``remove_blank_text`` that discard either all strings or whitespace-only strings from the result list. Bugs fixed ---------- * When moving Elements to another tree, the namespace cleanup mechanism no longer drops namespace prefixes from attributes for which it finds a default namespace declaration, to prevent them from appearing as unnamespaced attributes after serialisation. * Returning non-type objects from a custom class lookup method could lead to a crash. * Instantiating and using subtypes of Comments and ProcessingInstructions crashed. Other changes ------------- 3.2.0 (2013-04-28) ================== Features added -------------- Bugs fixed ---------- * LP#690319: Leading whitespace could change the behaviour of the string parsing functions in ``lxml.html``. * LP#599318: The string parsing functions in ``lxml.html`` are more robust in the face of uncommon HTML content like framesets or missing body tags. Patch by Stefan Seelmann. * LP#712941: I/O errors while trying to access files with paths that contain non-ASCII characters could raise ``UnicodeDecodeError`` instead of properly reporting the ``IOError``. * LP#673205: Parsing from in-memory strings disabled network access in the default parser and made subsequent attempts to parse from a URL fail. * LP#971754: lxml.html.clean appends 'nofollow' to 'rel' attributes instead of overwriting the current value. * LP#715687: lxml.html.clean no longer discards scripts that are explicitly allowed by the user provided whitelist. Patch by Christine Koppelt. Other changes ------------- 3.1.2 (2013-04-12) ================== Features added -------------- Bugs fixed ---------- * LP#1136509: Passing attributes through the namespace-unaware API of the sax bridge (i.e. the ``handler.startElement()`` method) failed with a ``TypeError``. Patch by Mike Bayer. * LP#1123074: Fix serialisation error in XSLT output when converting the result tree to a Unicode string. * GH#105: Replace illegal usage of ``xmlBufLength()`` in libxml2 2.9.0 by properly exported API function ``xmlBufUse()``. Other changes ------------- 3.1.1 (2013-03-29) ================== Features added -------------- Bugs fixed ---------- * LP#1160386: Write access to ``lxml.html.FormElement.fields`` raised an AttributeError in Py3. * Illegal memory access during cleanup in incremental xmlfile writer.

Initial import of py-lxml: lxml is a Pythonic binding for the libxml2 and libxslt libraries. It is unique in that it combines the speed and feature completeness of these libraries with the simplicity of a native Python API, mostly compatible but superior to the well-known ElementTree API.

Update py-lxml to 2.3.2. 2.3.2 (2011-11-11) ================== Features added -------------- * ``lxml.objectify.deannotate()`` has a new boolean option ``cleanup_namespaces`` to remove the objectify namespace declarations (and generally clean up the namespace declarations) after removing the type annotations. * ``lxml.objectify`` gained its own ``SubElement()`` function as a copy of ``etree.SubElement`` to avoid an otherwise redundant import of ``lxml.etree`` on the user side. Bugs fixed ---------- * Fixed the "descendant" bug in cssselect a second time (after a first fix in lxml 2.3.1). The previous change resulted in a serious performance regression for the XPath based evaluation of the translated expression. Note that this breaks the usage of some of the generated XPath expressions as XSLT location paths that previously worked in 2.3.1. * Fixed parsing of some selectors in cssselect. Whitespace after combinators ">", "+" and "~" is now correctly ignored. Previously is was parsed as a descendant combinator. For example, "div> .foo" was parsed the same as "div>* .foo" instead of "div>.foo". Other changes -------------- 2.3.1 (2011-09-25) ================== Features added -------------- * New option ``kill_tags`` in ``lxml.html.clean`` to remove specific tags and their content (i.e. their whole subtree). * ``pi.get()`` and ``pi.attrib`` on processing instructions to parse pseudo-attributes from the text content of processing instructions. * ``lxml.get_include()`` returns a list of include paths that can be used to compile external C code against lxml.etree. This is specifically required for statically linked lxml builds when code needs to compile against the exact same header file versions as lxml itself. * ``Resolver.resolve_file()`` takes an additional option ``close_file`` that configures if the file(-like) object will be closed after reading or not. By default, the file will be closed, as the user is not expected to keep a reference to it. Bugs fixed ---------- * HTML cleaning didn't remove 'data:' links. * The html5lib parser integration now uses the 'official' implementation in html5lib itself, which makes it work with newer releases of the library. * In ``lxml.sax``, ``endElementNS()`` could incorrectly reject a plain tag name when the corresponding start event inferred the same plain tag name to be in the default namespace. * When an open file-like object is passed into ``parse()`` or ``iterparse()``, the parser will no longer close it after use. This reverts a change in lxml 2.3 where all files would be closed. It is the users responsibility to properly close the file(-like) object, also in error cases. * Assertion error in lxml.html.cleaner when discarding top-level elements. * In lxml.cssselect, use the xpath 'A//B' (short for 'A/descendant-or-self::node()/B') instead of 'A/descendant::B' for the css descendant selector ('A B'). This makes a few edge cases like ``"div *:last-child"`` consistent with the selector behavior in WebKit and Firefox, and makes more css expressions valid location paths (for use in xsl:template match). * In lxml.html, non-selected ``<option>`` tags no longer show up in the collected form values. * Adding/removing ``<option>`` values to/from a multiple select form field properly selects them and unselects them. Other changes -------------- * Static builds can specify the download directory with the ``--download-dir`` option. 2.3 (2011-02-06) ================ Features added -------------- * When looking for children, ``lxml.objectify`` takes '{}tag' as meaning an empty namespace, as opposed to the parent namespace. Bugs fixed ---------- * When finished reading from a file-like object, the parser immediately calls its ``.close()`` method. * When finished parsing, ``iterparse()`` immediately closes the input file. * Work-around for libxml2 bug that can leave the HTML parser in a non-functional state after parsing a severly broken document (fixed in libxml2 2.7.8). * ``marque`` tag in HTML cleanup code is correctly named ``marquee``. Other changes -------------- * Some public functions in the Cython-level C-API have more explicit return types. 2.3beta1 (2010-09-06) ===================== Features added -------------- Bugs fixed ---------- * Crash in newer libxml2 versions when moving elements between documents that had attributes on replaced XInclude nodes. * ``XMLID()`` function was missing the optional ``parser`` and ``base_url`` parameters. * Searching for wildcard tags in ``iterparse()`` was broken in Py3. * ``lxml.html.open_in_browser()`` didn't work in Python 3 due to the use of os.tempnam. It now takes an optional 'encoding' parameter. Other changes -------------- 2.3alpha2 (2010-07-24) ====================== Features added -------------- Bugs fixed ---------- * Crash in XSLT when generating text-only result documents with a stylesheet created in a different thread. Other changes -------------- * ``repr()`` of Element objects shows the hex ID with leading 0x (following ElementTree 1.3). 2.3alpha1 (2010-06-19) ====================== Features added -------------- * Keyword argument ``namespaces`` in ``lxml.cssselect.CSSSelector()`` to pass a prefix-to-namespace mapping for the selector. * New function ``lxml.etree.register_namespace(prefix, uri)`` that globally registers a namespace prefix for a namespace that newly created Elements in that namespace will use automatically. Follows ElementTree 1.3. * Support 'unicode' string name as encoding parameter in ``tostring()``, following ElementTree 1.3. * Support 'c14n' serialisation method in ``ElementTree.write()`` and ``tostring()``, following ElementTree 1.3. * The ElementPath expression syntax (``el.find*()``) was extended to match the upcoming ElementTree 1.3 that will ship in the standard library of Python 3.2/2.7. This includes extended support for predicates as well as namespace prefixes (as known from XPath). * During regular XPath evaluation, various ESXLT functions are available within their namespace when using libxslt 1.1.26 or later. * Support passing a readily configured logger instance into ``PyErrorLog``, instead of a logger name. * On serialisation, the new ``doctype`` parameter can be used to override the DOCTYPE (internal subset) of the document. * New parameter ``output_parent`` to ``XSLTExtension.apply_templates()`` to append the resulting content directly to an output element. * ``XSLTExtension.process_children()`` to process the content of the XSLT extension element itself. * ISO-Schematron support based on the de-facto Schematron reference 'skeleton implementation'. * XSLT objects now take XPath object as ``__call__`` stylesheet parameters. * Enable path caching in ElementPath (``el.find*()``) to avoid parsing overhead. * Setting the value of a namespaced attribute always uses a prefixed namespace instead of the default namespace even if both declare the same namespace URI. This avoids serialisation problems when an attribute from a default namespace is set on an element from a different namespace. * XSLT extension elements: support for XSLT context nodes other than elements: document root, comments, processing instructions. * Support for strings (in addition to Elements) in node-sets returned by extension functions. * Forms that lack an ``action`` attribute default to the base URL of the document on submit. * XPath attribute result strings have an ``attrname`` property. * Namespace URIs get validated against RFC 3986 at the API level (required by the XML namespace specification). * Target parsers show their target object in the ``.target`` property (compatible with ElementTree). Bugs fixed ---------- * API is hardened against invalid proxy instances to prevent crashes due to incorrectly instantiated Element instances. * Prevent crash when instantiating ``CommentBase`` and friends. * Export ElementTree compatible XML parser class as ``XMLTreeBuilder``, as it is called in ET 1.2. * ObjectifiedDataElements in lxml.objectify were not hashable. They now use the hash value of the underlying Python value (string, number, etc.) to which they compare equal. * Parsing broken fragments in lxml.html could fail if the fragment contained an orphaned closing '</div>' tag. * Using XSLT extension elements around the root of the output document crashed. * ``lxml.cssselect`` did not distinguish between ``x[attr="val"]`` and ``x [attr="val"]`` (with a space). The latter now matches the attribute independent of the element. * Rewriting multiple links inside of HTML text content could end up replacing unrelated content as replacements could impact the reported position of subsequent matches. Modifications are now simplified by letting the ``iterlinks()`` generator in ``lxml.html`` return links in reversed order if they appear inside the same text node. Thus, replacements and link-internal modifications no longer change the position of links reported afterwards. * The ``.value`` attribute of ``textarea`` elements in lxml.html did not represent the complete raw value (including child tags etc.). It now serialises the complete content on read and replaces the complete content by a string on write. * Target parser didn't call ``.close()`` on the target object if parsing failed. Now it is guaranteed that ``.close()`` will be called after parsing, regardless of the outcome. Other changes ------------- * Official support for Python 3.1.2 and later. * Static MS Windows builds can now download their dependencies themselves. * ``Element.attrib`` no longer uses a cyclic reference back to its Element object. It therefore no longer requires the garbage collector to clean up. * Static builds include libiconv, in addition to libxml2 and libxslt. 2.2.8 (2010-09-02) ================== Bugs fixed ---------- * Crash in newer libxml2 versions when moving elements between documents that had attributes on replaced XInclude nodes. * Import fix for urljoin in Python 3.1+. 2.2.7 (2010-07-24) ================== Bugs fixed ---------- * Crash in XSLT when generating text-only result documents with a stylesheet created in a different thread.

Follows ElementTree 1.3. * Support 'unicode' string name as encoding parameter in ``tostring()``, following ElementTree 1.3. * Support 'c14n' serialisation method in ``ElementTree.write()`` and ``tostring()``, following ElementTree 1.3. * The ElementPath expression syntax (``el.find*()``) was extended to match the upcoming ElementTree 1.3 that will ship in the standard library of Python 3.2/2.7. This includes extended support for predicates as well as namespace prefixes (as known from XPath). * During regular XPath evaluation, various ESXLT functions are available within their namespace when using libxslt 1.1.26 or later. * Support passing a readily configured logger instance into ``PyErrorLog``, instead of a logger name. * On serialisation, the new ``doctype`` parameter can be used to override the DOCTYPE (internal subset) of the document. * New parameter ``output_parent`` to ``XSLTExtension.apply_templates()`` to append the resulting content directly to an output element. * ``XSLTExtension.process_children()`` to process the content of the XSLT extension element itself. * ISO-Schematron support based on the de-facto Schematron reference 'skeleton implementation'. * XSLT objects now take XPath object as ``__call__`` stylesheet parameters. * Enable path caching in ElementPath (``el.find*()``) to avoid parsing overhead. * Setting the value of a namespaced attribute always uses a prefixed namespace instead of the default namespace even if both declare the same namespace URI. This avoids serialisation problems when an attribute from a default namespace is set on an element from a different namespace. * XSLT extension elements: support for XSLT context nodes other than elements: document root, comments, processing instructions. * Support for strings (in addition to Elements) in node-sets returned by extension functions. * Forms that lack an ``action`` attribute default to the base URL of the document on submit. * XPath attribute result strings have an ``attrname`` property. * Namespace URIs get validated against RFC 3986 at the API level (required by the XML namespace specification). * Target parsers show their target object in the ``.target`` property (compatible with ElementTree). Bugs fixed ---------- * API is hardened against invalid proxy instances to prevent crashes due to incorrectly instantiated Element instances. * Prevent crash when instantiating ``CommentBase`` and friends. * Export ElementTree compatible XML parser class as ``XMLTreeBuilder``, as it is called in ET 1.2. * ObjectifiedDataElements in lxml.objectify were not hashable. They now use the hash value of the underlying Python value (string, number, etc.) to which they compare equal. * Parsing broken fragments in lxml.html could fail if the fragment contained an orphaned closing '</div>' tag. * Using XSLT extension elements around the root of the output document crashed. * ``lxml.cssselect`` did not distinguish between ``x[attr="val"]`` and ``x [attr="val"]`` (with a space). The latter now matches the attribute independent of the element. * Rewriting multiple links inside of HTML text content could end up replacing unrelated content as replacements could impact the reported position of subsequent matches. Modifications are now simplified by letting the ``iterlinks()`` generator in ``lxml.html`` return links in reversed order if they appear inside the same text node. Thus, replacements and link-internal modifications no longer change the position of links reported afterwards. * The ``.value`` attribute of ``textarea`` elements in lxml.html did not represent the complete raw value (including child tags etc.). It now serialises the complete content on read and replaces the complete content by a string on write. * Target parser didn't call ``.close()`` on the target object if parsing failed. Now it is guaranteed that ``.close()`` will be called after parsing, regardless of the outcome. Other changes ------------- * Official support for Python 3.1.2 and later. * Static MS Windows builds can now download their dependencies themselves. * ``Element.attrib`` no longer uses a cyclic reference back to its Element object. It therefore no longer requires the garbage collector to clean up. * Static builds include libiconv, in addition to libxml2 and libxslt. 2.2.8 (2010-09-02) ================== Bugs fixed ---------- * Crash in newer libxml2 versions when moving elements between documents that had attributes on replaced XInclude nodes. * Import fix for urljoin in Python 3.1+. 2.2.7 (2010-07-24) ================== Bugs fixed ---------- * Crash in XSLT when generating text-only result documents with a stylesheet created in a different thread.

Update to 3.0.1. Remove unnecessary setuptools dependency. Mark as python3-ready. 3.0.1 (2012-10-14) ================== Bugs fixed ---------- * LP#1065924: Element proxies could disappear during garbage collection in PyPy without proper cleanup. * GH#71: Failure to work with libxml2 2.6.x. * LP#1065139: static MacOS-X build failed in Py3. 3.0 (2012-10-08) ================ Bugs fixed ---------- * End-of-file handling was incorrect in iterparse() when reading from a low-level C file stream and failed in libxml2 2.9.0 due to its improved consistency checks. Other changes ------------- * The build no longer uses Cython by default unless the generated C files are missing. To use Cython, pass the option "--with-cython". To ignore the fatal build error when Cython is required but not available (e.g. to run special setup.py commands that do not actually run a build), pass "--without-cython". 3.0beta1 (2012-09-26) ===================== Features added -------------- * Python level access to (optional) libxml2 memory debugging features to simplify debugging of memory leaks etc. Bugs fixed ---------- * Fix a memory leak in XPath by switching to Cython 0.17.1. * Some tests were adapted to work with PyPy. Other changes ------------- * The code was adapted to work with the upcoming libxml2 2.9.0 release. 3.0alpha2 (2012-08-23) ====================== Features added -------------- * The ``.iter()`` method of elements now accepts ``tag`` arguments like ``"{*}name"`` to search for elements with a given local name in any namespace. With this addition, all combinations of wildcards now work as expected: ``"{ns}name"``, ``"{}name"``, ``"{*}name"``, ``"{ns}*"``, ``"{}*"`` and ``"{*}*"``. Note that ``"name"`` is equivalent to ``"{}name"``, but ``"*"`` is ``"{*}*"``. The same change applies to the ``.getiterator()``, ``.itersiblings()``, ``.iterancestors()``, ``.iterdescendants()``, ``.iterchildren()`` and ``.itertext()`` methods;the ``strip_attributes()``, ``strip_elements()`` and ``strip_tags()`` functions as well as the ``iterparse()`` class. * C14N allows specifying the inclusive prefixes to be promoted to top-level during exclusive serialisation. Bugs fixed ---------- * Passing long Unicode strings into the ``feed()`` parser interface failed to read the entire string. 3.0alpha1 (2012-07-31) ====================== Features added -------------- * Initial support for building in PyPy (through cpyext). * DTD objects gained an API that allows read access to their declarations. * ``xpathgrep.py`` gained support for parsing line-by-line (e.g. from grep output) and for surrounding the output with a new root tag. * ``E-factory`` in ``lxml.builder`` accepts subtypes of known data types (such as string subtypes) when building elements around them. * Tree iteration and ``iterparse()`` with a selective ``tag`` argument supports passing a set of tags. Tree nodes will be returned by the iterators if they match any of the tags. Bugs fixed ---------- * The ``.find*()`` methods in ``lxml.objectify`` no longer use XPath internally, which makes them faster in many cases (especially when short circuiting after a single or couple of elements) and fixes some behavioural differences compared to ``lxml.etree``. Note that this means that they no longer support arbitrary XPath expressions but only the subset that the ``ElementPath`` language supports. The previous implementation was also redundant with the normal XPath support, which can be used as a replacement. * ``el.find('*')`` could accidentally return a comment or processing instruction that happened to be in the wrong spot. (Same for the other ``.find*()`` methods.) * The error logging is less intrusive and avoids a global setup where possible. * Fixed undefined names in html5lib parser. * ``xpathgrep.py`` did not work in Python 3. * ``Element.attrib.update()`` did not accept an ``attrib`` of another Element as parameter. * For subtypes of ``ElementBase`` that make the ``.text`` or ``.tail`` properties immutable (as in objectify, for example), inserting text when creating Elements through the E-Factory feature of the class constructor would fail with an exception, stating that the text cannot be modified. Other changes -------------- * The code base was overhauled to properly use 'const' where the API of libxml2 and libxslt requests it. This also has an impact on the public C-API of lxml itself, as defined in ``etreepublic.pxd``, as well as the provided declarations in the ``lxml/includes/`` directory. Code that uses these declarations may have to be adapted. On the plus side, this fixes several C compiler warnings, also for user code, thus making it easier to spot real problems again. * The functionality of "lxml.cssselect" was moved into a separate PyPI package called "cssselect". To continue using it, you must install that package separately. The "lxml.cssselect" module is still available and provides the same interface, provided the "cssselect" package can be imported at runtime. * Element attributes passed in as an ``attrib`` dict or as keyword arguments are now sorted by (namespaced) name before being created to make their order predictable for serialisation and iteration. Note that adding or deleting attributes afterwards does not take that order into account, i.e. setting a new attribute appends it after the existing ones. * Several classes that are for internal use only were removed from the ``lxml.etree`` module dict: ``_InputDocument, _ResolverRegistry, _ResolverContext, _BaseContext, _ExsltRegExp, _IterparseContext, _TempStore, _ExceptionContext, __ContentOnlyElement, _AttribIterator, _NamespaceRegistry, _ClassNamespaceRegistry, _FunctionNamespaceRegistry, _XPathFunctionNamespaceRegistry, _ParserDictionaryContext, _FileReaderContext, _ParserContext, _PythonSaxParserTarget, _TargetParserContext, _ReadOnlyProxy, _ReadOnlyPIProxy, _ReadOnlyEntityProxy, _ReadOnlyElementProxy, _OpaqueNodeWrapper, _OpaqueDocumentWrapper, _ModifyContentOnlyProxy, _ModifyContentOnlyPIProxy, _ModifyContentOnlyEntityProxy, _AppendOnlyElementProxy, _SaxParserContext, _FilelikeWriter, _ParserSchemaValidationContext, _XPathContext, _XSLTResolverContext, _XSLTContext, _XSLTQuotedStringParam`` * Several internal classes can no longer be inherited from: ``_InputDocument, _ResolverRegistry, _ExsltRegExp, _ElementUnicodeResult, _IterparseContext, _TempStore, _AttribIterator, _ClassNamespaceRegistry, _XPathFunctionNamespaceRegistry, _ParserDictionaryContext, _FileReaderContext, _PythonSaxParserTarget, _TargetParserContext, _ReadOnlyPIProxy, _ReadOnlyEntityProxy, _OpaqueDocumentWrapper, _ModifyContentOnlyPIProxy, _ModifyContentOnlyEntityProxy, _AppendOnlyElementProxy, _FilelikeWriter, _ParserSchemaValidationContext, _XPathContext, _XSLTResolverContext, _XSLTContext, _XSLTQuotedStringParam, _XSLTResultTree, _XSLTProcessingInstruction`` 2.3.6 (2012-09-28) ================== Bugs fixed ---------- * Passing long Unicode strings into the ``feed()`` parser interface failed to read the entire string. 2.3.5 (2012-07-31) ================== Bugs fixed ---------- * Crash when merging text nodes in ``element.remove()``. * Crash in sax/target parser when reporting empty doctype. 2.3.4 (2012-03-26) ================== Bugs fixed ---------- * Crash when building an nsmap (Element property) with empty namespace URIs. * Crash due to race condition when errors (or user messages) occur during threaded XSLT processing. * XSLT stylesheet compilation could ignore compilation errors. 2.3.3 (2012-01-04) ================== Features added -------------- * ``lxml.html.tostring()`` gained new serialisation options ``with_tail`` and ``doctype``. Bugs fixed ---------- * Fixed a crash when using ``iterparse()`` for HTML parsing and requesting start events. * Fixed parsing of more selectors in cssselect. Whitespace before pseudo-elements and pseudo-classes is significant as it is a descendant combinator. "E :pseudo" should parse the same as "E \*:pseudo", not "E:pseudo". Patch by Simon Sapin. * lxml.html.diff no longer raises an exception when hitting 'img' tags without 'src' attribute.

Update to py-lxml-2.2.3: * The resolve_entities option did not work in the incremental feed parser. * Looking up and deleting attributes without a namespace could hit a namespaced attribute of the same name instead. * Late errors during calls to SubElement() (e.g. attribute related ones) could leave a partially initialised element in the tree. * Modifying trees that contain parsed entity references could result in an infinite loop. * ObjectifiedElement.__setattr__ created an empty-string child element when the attribute value was rejected as a non-unicode/ non-ascii string * Syntax errors in lxml.cssselect could result in misleading error messages. * Invalid syntax in CSS expressions could lead to an infinite loop in the parser of lxml.cssselect. * CSS special character escapes were not properly handled in lxml.cssselect. * CSS Unicode escapes were not properly decoded in lxml.cssselect. * Select options in HTML forms that had no explicit value attribute were not handled correctly. The HTML standard dictates that their value is defined by their text content. This is now supported by lxml.html. * XPath raised a TypeError when finding CDATA sections. This is now fully supported. * Calling help(lxml.objectify) didn't work at the prompt. * The ElementMaker in lxml.objectify no longer defines the default namespaces when annotation is disabled. * Feed parser failed to honout the 'recover' option on parse errors. * Diverting the error logging to Python's logging system was broken. Require setuptools-0.6c11 as it fails at least with newer Python 2.6 otherwise.

Update to 3.1.0: 3.1.0 (2013-02-10) ================== Features added -------------- * GH#89: lxml.html.clean allows overriding the set of attributes that it considers 'safe'. Patch by Francis Devereux. Bugs fixed ---------- * LP#1104370: ``copy.copy(el.attrib)`` raised an exception. It now returns a copy of the attributes as a plain Python dict. * GH#95: When used with namespace prefixes, the ``el.find*()`` methods always used the first namespace mapping that was provided for each path expression instead of using the one that was actually passed in for the current run. * LP#1092521, GH#91: Fix undefined C symbol in Python runtimes compiled without threading support. Patch by Ulrich Seidl. Other changes ------------- 3.1beta1 (2012-12-21) ===================== Features added -------------- * New build-time option ``--with-unicode-strings`` for Python 2 that makes the API always return Unicode strings for names and text instead of byte strings for plain ASCII content. * New incremental XML file writing API ``etree.xmlfile()``. * E factory in lxml.objectify is callable to simplify the creation of tags with non-identifier names without having to resort to getattr(). Bugs fixed ---------- * When starting from a non-namespaced element in lxml.objectify, searching for a child without explicitly specifying a namespace incorrectly found namespaced elements with the requested local name, instead of restricting the search to non-namespaced children. * GH#85: Deprecation warnings were fixed for Python 3.x. * GH#33: lxml.html.fromstring() failed to accept bytes input in Py3. * LP#1080792: Static build of libxml2 2.9.0 failed due to missing file. Other changes ------------- * The externally useless class ``_ObjectifyElementMakerCaller`` was removed from the module API of lxml.objectify. * LP#1075622: lxml.builder is faster for adding text to elements with many children. Patch by Anders Hammarquist.

.include "../../lang/python/distutils.mk"
Update py-lxml to 2.3.2. 2.3.2 (2011-11-11) ================== Features added -------------- * ``lxml.objectify.deannotate()`` has a new boolean option ``cleanup_namespaces`` to remove the objectify namespace declarations (and generally clean up the namespace declarations) after removing the type annotations. * ``lxml.objectify`` gained its own ``SubElement()`` function as a copy of ``etree.SubElement`` to avoid an otherwise redundant import of ``lxml.etree`` on the user side. Bugs fixed ---------- * Fixed the "descendant" bug in cssselect a second time (after a first fix in lxml 2.3.1). The previous change resulted in a serious performance regression for the XPath based evaluation of the translated expression. Note that this breaks the usage of some of the generated XPath expressions as XSLT location paths that previously worked in 2.3.1. * Fixed parsing of some selectors in cssselect. Whitespace after combinators ">", "+" and "~" is now correctly ignored. Previously is was parsed as a descendant combinator. For example, "div> .foo" was parsed the same as "div>* .foo" instead of "div>.foo". Other changes -------------- 2.3.1 (2011-09-25) ================== Features added -------------- * New option ``kill_tags`` in ``lxml.html.clean`` to remove specific tags and their content (i.e. their whole subtree). * ``pi.get()`` and ``pi.attrib`` on processing instructions to parse pseudo-attributes from the text content of processing instructions. * ``lxml.get_include()`` returns a list of include paths that can be used to compile external C code against lxml.etree. This is specifically required for statically linked lxml builds when code needs to compile against the exact same header file versions as lxml itself. * ``Resolver.resolve_file()`` takes an additional option ``close_file`` that configures if the file(-like) object will be closed after reading or not. By default, the file will be closed, as the user is not expected to keep a reference to it. Bugs fixed ---------- * HTML cleaning didn't remove 'data:' links. * The html5lib parser integration now uses the 'official' implementation in html5lib itself, which makes it work with newer releases of the library. * In ``lxml.sax``, ``endElementNS()`` could incorrectly reject a plain tag name when the corresponding start event inferred the same plain tag name to be in the default namespace. * When an open file-like object is passed into ``parse()`` or ``iterparse()``, the parser will no longer close it after use. This reverts a change in lxml 2.3 where all files would be closed. It is the users responsibility to properly close the file(-like) object, also in error cases. * Assertion error in lxml.html.cleaner when discarding top-level elements. * In lxml.cssselect, use the xpath 'A//B' (short for 'A/descendant-or-self::node()/B') instead of 'A/descendant::B' for the css descendant selector ('A B'). This makes a few edge cases like ``"div *:last-child"`` consistent with the selector behavior in WebKit and Firefox, and makes more css expressions valid location paths (for use in xsl:template match). * In lxml.html, non-selected ``<option>`` tags no longer show up in the collected form values. * Adding/removing ``<option>`` values to/from a multiple select form field properly selects them and unselects them. Other changes -------------- * Static builds can specify the download directory with the ``--download-dir`` option. 2.3 (2011-02-06) ================ Features added -------------- * When looking for children, ``lxml.objectify`` takes '{}tag' as meaning an empty namespace, as opposed to the parent namespace. Bugs fixed ---------- * When finished reading from a file-like object, the parser immediately calls its ``.close()`` method. * When finished parsing, ``iterparse()`` immediately closes the input file. * Work-around for libxml2 bug that can leave the HTML parser in a non-functional state after parsing a severly broken document (fixed in libxml2 2.7.8). * ``marque`` tag in HTML cleanup code is correctly named ``marquee``. Other changes -------------- * Some public functions in the Cython-level C-API have more explicit return types. 2.3beta1 (2010-09-06) ===================== Features added -------------- Bugs fixed ---------- * Crash in newer libxml2 versions when moving elements between documents that had attributes on replaced XInclude nodes. * ``XMLID()`` function was missing the optional ``parser`` and ``base_url`` parameters. * Searching for wildcard tags in ``iterparse()`` was broken in Py3. * ``lxml.html.open_in_browser()`` didn't work in Python 3 due to the use of os.tempnam. It now takes an optional 'encoding' parameter. Other changes -------------- 2.3alpha2 (2010-07-24) ====================== Features added -------------- Bugs fixed ---------- * Crash in XSLT when generating text-only result documents with a stylesheet created in a different thread. Other changes -------------- * ``repr()`` of Element objects shows the hex ID with leading 0x (following ElementTree 1.3). 2.3alpha1 (2010-06-19) ====================== Features added -------------- * Keyword argument ``namespaces`` in ``lxml.cssselect.CSSSelector()`` to pass a prefix-to-namespace mapping for the selector. * New function ``lxml.etree.register_namespace(prefix, uri)`` that globally registers a namespace prefix for a namespace that newly created Elements in that namespace will use automatically.

Other changes -------------- * ``repr()`` of Element objects shows the hex ID with leading 0x (following ElementTree 1.3). 2.3alpha1 (2010-06-19) ====================== Features added -------------- * Keyword argument ``namespaces`` in ``lxml.cssselect.CSSSelector()`` to pass a prefix-to-namespace mapping for the selector. * New function ``lxml.etree.register_namespace(prefix, uri)`` that globally registers a namespace prefix for a namespace that newly created Elements in that namespace will use automatically. Follows ElementTree 1.3. * Support 'unicode' string name as encoding parameter in ``tostring()``, following ElementTree 1.3. * Support 'c14n' serialisation method in ``ElementTree.write()`` and ``tostring()``, following ElementTree 1.3. * The ElementPath expression syntax (``el.find*()``) was extended to match the upcoming ElementTree 1.3 that will ship in the standard library of Python 3.2/2.7. This includes extended support for predicates as well as namespace prefixes (as known from XPath). * During regular XPath evaluation, various ESXLT functions are available within their namespace when using libxslt 1.1.26 or later. * Support passing a readily configured logger instance into ``PyErrorLog``, instead of a logger name. * On serialisation, the new ``doctype`` parameter can be used to override the DOCTYPE (internal subset) of the document. * New parameter ``output_parent`` to ``XSLTExtension.apply_templates()`` to append the resulting content directly to an output element. * ``XSLTExtension.process_children()`` to process the content of the XSLT extension element itself. * ISO-Schematron support based on the de-facto Schematron reference 'skeleton implementation'. * XSLT objects now take XPath object as ``__call__`` stylesheet parameters. * Enable path caching in ElementPath (``el.find*()``) to avoid parsing overhead. * Setting the value of a namespaced attribute always uses a prefixed namespace instead of the default namespace even if both declare the same namespace URI. This avoids serialisation problems when an attribute from a default namespace is set on an element from a different namespace. * XSLT extension elements: support for XSLT context nodes other than elements: document root, comments, processing instructions. * Support for strings (in addition to Elements) in node-sets returned by extension functions. * Forms that lack an ``action`` attribute default to the base URL of the document on submit. * XPath attribute result strings have an ``attrname`` property. * Namespace URIs get validated against RFC 3986 at the API level (required by the XML namespace specification). * Target parsers show their target object in the ``.target`` property (compatible with ElementTree). Bugs fixed ---------- * API is hardened against invalid proxy instances to prevent crashes due to incorrectly instantiated Element instances. * Prevent crash when instantiating ``CommentBase`` and friends. * Export ElementTree compatible XML parser class as ``XMLTreeBuilder``, as it is called in ET 1.2. * ObjectifiedDataElements in lxml.objectify were not hashable. They now use the hash value of the underlying Python value (string, number, etc.) to which they compare equal. * Parsing broken fragments in lxml.html could fail if the fragment contained an orphaned closing '</div>' tag. * Using XSLT extension elements around the root of the output document crashed. * ``lxml.cssselect`` did not distinguish between ``x[attr="val"]`` and ``x [attr="val"]`` (with a space). The latter now matches the attribute independent of the element. * Rewriting multiple links inside of HTML text content could end up replacing unrelated content as replacements could impact the reported position of subsequent matches. Modifications are now simplified by letting the ``iterlinks()`` generator in ``lxml.html`` return links in reversed order if they appear inside the same text node. Thus, replacements and link-internal modifications no longer change the position of links reported afterwards. * The ``.value`` attribute of ``textarea`` elements in lxml.html did not represent the complete raw value (including child tags etc.). It now serialises the complete content on read and replaces the complete content by a string on write. * Target parser didn't call ``.close()`` on the target object if parsing failed. Now it is guaranteed that ``.close()`` will be called after parsing, regardless of the outcome. Other changes ------------- * Official support for Python 3.1.2 and later. * Static MS Windows builds can now download their dependencies themselves. * ``Element.attrib`` no longer uses a cyclic reference back to its Element object. It therefore no longer requires the garbage collector to clean up. * Static builds include libiconv, in addition to libxml2 and libxslt. 2.2.8 (2010-09-02) ================== Bugs fixed ---------- * Crash in newer libxml2 versions when moving elements between documents that had attributes on replaced XInclude nodes. * Import fix for urljoin in Python 3.1+. 2.2.7 (2010-07-24) ================== Bugs fixed ---------- * Crash in XSLT when generating text-only result documents with a stylesheet created in a different thread.

BUILDLINK_API_DEPENDS.libxslt+= libxslt>=1.1.26
Initial import of py-lxml: lxml is a Pythonic binding for the libxml2 and libxslt libraries. It is unique in that it combines the speed and feature completeness of these libraries with the simplicity of a native Python API, mostly compatible but superior to the well-known ElementTree API.
