Hi all, the first alpha release of lxml 2.1 is on PyPI. This is a "cleanup and new features" release that follows the current stable 2.0 series. The major new features are XSLT extension elements and support for comments/PIs in iterparse(). A lot of formerly deprecated API functions were finally removed, so you may have to adapt your code (a little). After the change, it will continue to run with both lxml 2.0.x and 2.1. Have fun, Stefan 2.1alpha1 (2008-03-27) Features added * New event types 'comment' and 'pi' in iterparse(). * XSLTAccessControl instances have a property options that returns a dict of access configuration options. * Constant instances DENY_ALL and DENY_WRITE on XSLTAccessControl class. * Extension elements for XSLT (experimental!) * Element.base property returns the xml:base or HTML base URL of an Element. * docinfo.URL property is writable. Bugs fixed * Default encoding for plain text serialisation was different from that of XML serialisation (UTF-8 instead of ASCII). Other changes * Minor API speed-ups. * The benchmark suite now uses tail text in the trees, which makes the absolute numbers incomparable to previous results. * Generating the HTML documentation now requires Pygments, which is used to enable syntax highlighting for the doctest examples. Most long-time deprecated functions and methods were removed: * etree.clearErrorLog(), use etree.clear_error_log() * etree.useGlobalPythonLog(), use etree.use_global_python_log() * etree.ElementClassLookup.setFallback(), use etree.ElementClassLookup.set_fallback() * etree.getDefaultParser(), use etree.get_default_parser() * etree.setDefaultParser(), use etree.set_default_parser() * etree.setElementClassLookup(), use etree.set_element_class_lookup() Note that parser.setElementClassLookup() has not been removed yet, although parser.set_element_class_lookup() should be used instead. * xpath_evaluator.registerNamespace(), use xpath_evaluator.register_namespace() * xpath_evaluator.registerNamespaces(), use xpath_evaluator.register_namespaces() * objectify.setPytypeAttributeTag, use objectify.set_pytype_attribute_tag * objectify.setDefaultParser(), use objectify.set_default_parser()
