Hi all, I'm proud to announce the release of lxml 1.3. This is a major new release with various new features and lots of fixes compared to the 1.2 series. The complete changelog follows below. Major objectives of this release were: - API consolidation: make everything work with everything - improved namespace handling: avoid redundant namespaces wherever possible - simplicity and accessibility: improved, restructured documentation and simpler XML/HTML generation Future versions of lxml will continue this trend to make lxml the leading tool for XML and HTML in the Python world. Have fun, Stefan Behnel 1.3 (2007-06-24) ================ Features added -------------- * Module ``lxml.pyclasslookup`` implemens an Element class lookup scheme that can access the entire tree to determine a suitable Element class * Parsers take a ``remove_comments`` keyword argument that skips over comments * ``parse()`` function in ``objectify``, corresponding to ``XML()`` etc. * ``Element.addnext(el)`` and ``Element.addprevious(el)`` methods to support adding processing instructions and comments around the root node * Extended type annotation in objectify: cleaner annotation namespace setup plus new ``deannotate()`` function * Support for custom Element class instantiation in lxml.sax: passing a ``makeelement()`` function to the ElementTreeContentHandler will reuse the lookup context of that function * '.' represents empty ObjectPath (identity) Bugs fixed ---------- * Removing Elements from a tree could make them loose their namespace declarations * ``ElementInclude`` didn't honour base URL of original document * Replacing the children slice of an Element would cut off the tails of the original children * ``Element.getiterator(tag)`` did not accept ``Comment`` and ``ProcessingInstruction`` as tags * API functions now check incoming strings for XML conformity. Zero bytes or low ASCII characters are no longer accepted. * XSLT parsing failed to pass resolver context on to imported documents * More ET compatible behaviour when writing out XML declarations or not * ``Element.attrib`` was missing ``clear()`` and ``pop()`` methods * More robust error handling in ``iterparse()`` * Documents lost their top-level PIs and comments on serialisation * lxml.sax failed on comments and PIs. Comments are now properly ignored and PIs are copied. * Raise AssertionError when passing strings containing '\0' bytes 1.3beta (2007-02-27) ==================== Features added -------------- * ``DTD`` validator class (like ``RelaxNG`` and ``XMLSchema``) * HTML generator helpers by Fredrik Lundh in ``lxml.htmlbuilder`` * ``ElementMaker`` XML generator by Fredrik Lundh in ``lxml.builder.E`` * Support for pickeling ``objectify.ObjectifiedElement`` objects to XML * ``update()`` method on Element.attrib * Optimised replacement for libxml2's _xmlReconsiliateNs(). This allows lxml a better handling of namespaces when moving elements between documents. Bugs fixed ---------- * Possible memory leaks in namespace handling when moving elements between documents Other changes ------------- * major restructuring in the documentation
