Hallo everyone, I have the honour to announce the availability of lxml 1.0 on cheeseshop. While the list of features added since the beta version (1.0.beta) is rather small, this version contains a pretty large number of bug fixes found by various users and testers. Thank you all for your help! Features added since 0.9.2: * Element.getiterator() and the findall() methods support finding arbitrary elements from a namespace (pattern {namespace}*) * Another speedup in tree iteration code * General speedup of Python Element object creation and deallocation * Writing C14N no longer serializes in memory (reduced memory footprint) * PyErrorLog for error logging through the Python logging module * element.getroottree() returns an ElementTree for the root node of the document that contains the element. * ElementTree.getpath(element) returns a simple, absolute XPath expression to find the element in the tree structure * Error logs have a last_error attribute for convenience * Comment texts can be changed through the API * Formatted output via pretty_print keyword to serialization functions * XSLT can block access to file system and network via XSLTAccessControl * ElementTree.write() no longer serializes in memory (reduced memory footprint) * Speedup of Element.findall(tag) and Element.getiterator(tag) * Support for writing the XML representation of Elements and ElementTrees to Python unicode strings via etree.tounicode() * Support for writing XSLT results to Python unicode strings via unicode() * Parsing a unicode string no longer copies the string (reduced memory footprint) * Parsing file-like objects now reads chunks rather than the whole file (reduced memory footprint) * Parsing StringIO objects from the start avoids copying the string (reduced memory footprint) * Read-only 'docinfo' attribute in ElementTree class holds DOCTYPE information, original encoding and XML version as seen by the parser * etree module can be compiled without libxslt by commenting out the line include "xslt.pxi" near the end of the etree.pyx source file * Better error messages in parser exceptions * Error reporting now also works in XSLT * Support for custom document loaders (URI resolvers) in parsers and XSLT, resolvers are registered at parser level * Implementation of exslt:regexp for XSLT based on the Python 're' module, enabled by default, can be switched off with 'regexp=False' keyword argument * Support for exslt extensions (libexslt) and libxslt extra functions (node-set, document, write, output) * Substantial speedup in XPath.evaluate() * HTMLParser for parsing (broken) HTML * XMLDTDID function parses XML into tuple (root node, ID dict) based on xml:id implementation of libxml2 (as opposed to ET compatible XMLID) Bugs fixed since 0.9.2: * Memory leak in Element.__setitem__ * Memory leak in Element.attrib.items() and Element.attrib.values() * Memory leak in XPath extension functions * Memory leak in unicode related setup code * Element now raises ValueError on empty tag names * Namespace fixing after moving elements between documents could fail if the source document was freed too early * Setting namespace-less tag names on namespaced elements ('{ns}t' -> 't') didn't reset the namespace * Unknown constants from newer libxml2 versions could raise exceptions in the error handlers * lxml.etree compiles much faster * On libxml2 <= 2.6.22, parsing strings with encoding declaration could fail in certain cases * Document reference in ElementTree objects was not updated when the root element was moved to a different document * Running absolute XPath expressions on an Element now evaluates against the root tree * Evaluating absolute XPath expressions (/*) on an ElementTree could fail * Crashes when calling XSLT, RelaxNG, etc. with uninitialized ElementTree objects * Removed public function initThreadLogging(), replaced by more general initThread() which fixes a number of setup problems in threads * Memory leak when using iconv encoders in tostring/write * Deep copying Elements and ElementTrees maintains the document information * Serialization functions raise LookupError for unknown encodings * Memory deallocation crash resulting from deep copying elements * Some ElementTree methods could crash if the root node was not initialized (neither file nor element passed to the constructor) * Element/SubElement failed to set attribute namespaces from passed attrib dictionary * tostring() now adds an XML declaration for non-ASCII encodings * tostring() failed to serialize encodings that contain 0-bytes * ElementTree.xpath() and XPathDocumentEvaluator were not using the ElementTree root node as reference point * Calling document('') in XSLT failed to return the stylesheet I feel a certain fascination when I look back on the relatively short time it took Martijn and me (and several other contributors) to implement the large set of features that this version has and to bring it to this level of maturity. A big "Thank you!" to all code contributors, egg builders, bug finders, testers, users and everyone else who helped in bringing lxml towards 1.0! Stefan
