Hi everyone, I'm proud to announce the second alpha release of lxml 3.0. This release features initial support for PyPy and a new tree API for DTDs (by Walter Dörwald), as well as some major cleanups in the code base. The lxml.cssselect package was moved into a separate PyPI project nicely extended and maintained by Simon Sapin. Originally, this release was targeted as lxml 2.4, but some major improvements as well as a couple of potentially incompatible changes make "3.0" appear more appropriate. This release is available from PyPI: http://pypi.python.org/pypi/lxml/3.0alpha2 The documentation is here: http://lxml.de/3.0/ Download: http://lxml.de/files/lxml-3.0alpha2.tgz Signature: http://lxml.de/files/lxml-3.0alpha2.tgz.asc GitHub: https://github.com/lxml/lxml/commit/ff1ba90049003f8badfb0a833125d09d8692af1d This release was built using Cython 0.17b3. If you are interested in commercial support or customisations for the lxml package, please contact me directly. Have fun, Stefan 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() function. * 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. Other changes ------------- * The code was adapted to work with the upcoming libxml2 2.9.0 release. 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
