lxml 1.1 and 1.0.4 released
by Stefan Behnel Sept. 13, 2006

Sept. 13, 2006

Hi all, I'm proud to announce the release of lxml 1.1, right after lxml 1.0.4. http://codespeak.net/lxml/ Download: http://cheeseshop.python.org/pypi/lxml/1.1 http://cheeseshop.python.org/pypi/lxml/1.0.4 lxml 1.1 is a major new release that introduces many new features compared to the 1.0 series. lxml 1.0.4 is a maintenance release for the stable 1.0 series. For a quick introduction: """ lxml is a Pythonic binding for the libxml2 and libxslt libraries. It provides safe and convenient access to these libraries using the ElementTree API. It extends the ElementTree API significantly to offer support for XPath, RelaxNG, XML Schema, XSLT, C14N and much, much more. Its goals are: * Pythonic API. * Documented. http://codespeak.net/lxml/#documentation http://codespeak.net/lxml/FAQ.html * FAST! http://codespeak.net/lxml/performance.html * Use Python unicode strings in API. * Safe (no segfaults). * No manual memory management! (as opposed to the official libxml2 Python bindings) """ The main improvements in the 1.1 series are: * threading support * XPath axis iteration * iterparse() and iterwalk() * configurable Element class lookup methods * lxml.objectify - a data binding API on top of lxml.etree The complete changelog is below. lxml 1.1 has been tested in an alpha and beta version and received various bug fixes before the final release. It is currently considered stable and ready for production use, whereas the 1.0 series are considered rock-stable and may still be the right thing to choose for more conservative environments. Bug-fix releases and minor improvements to the 1.1 and 1.0 series will continue to become available at need. That way, 1.1 will soon be considered as stable as 1.0 to become its the main line successor. Given the many helpful egg contributions we received for past releases, I hope that 1.1 (and 1.0.4) will be as well supported in that regard to help in further increasing our community. Thanks to everyone who helped in getting 1.1 done, in getting bugs fixed and helping others in using it. Have fun, Stefan *** Changes in 1.0.4: 1.0.4 (2006-09-09) Features added * List-like Element.extend() method Bugs fixed * Crash in tail handling in Element.replace() *** Changes in 1.1: 1.1 (2006-09-13) ================ Features added -------------- * Comments and processing instructions return '' and '<?pi-target content?>' for repr() * Parsers are now the preferred (and default) place where element class lookup schemes should be registered. Namespace lookup is no longer supported by default. Bugs fixed ---------- * filenames with local 8-bit encoding were not supported * 1.1beta did not compile under Python 2.3 * ignore unknown 'pyval' attribute values in objectify * objectify.ObjectifiedElement.addattr() failed to accept Elements and Lists * objectify.ObjectPath.setattr() failed to accept Elements and Lists 1.1beta (2006-08-08) ==================== Features added -------------- * Support for Python 2.5 beta * Unlock the GIL for deep copying documents and for XPath() * New ``compact`` keyword argument for parsing read-only documents * Support for parser options in iterparse() * The ``namespace`` axis is supported in XPath and returns (prefix, URI) tuples * The XPath expression "/" now returns an empty list instead of raising an exception * XML-Object API on top of lxml (lxml.objectify) * Customizable Element class lookup: * different pre-implemented lookup mechanisms * support for externally provided lookup functions * Support for processing instructions (ET-like, not compatible) * Public C-level API for independent extension modules Bugs fixed ---------- * XPathSyntaxError now inherits from XPathError * Threading race conditions in RelaxNG and XMLSchema * Crash when mixing elements from XSLT results into other trees, concurrent XSLT is only allowed when the stylesheet was parsed in the main thread * The EXSLT ``regexp:match`` function now works as defined (except for some differences in the regular expression syntax) * Setting element.text to '' returned None on request, not the empty string * ``iterparse()`` could crash on long XML files * Creating documents no longer copies the parser for later URL resolving. For performance reasons, only a reference is kept. Resolver updates on the parser will now be reflected by documents that were parsed before the change. Although this should rarely become visible, it is a behavioral change from 1.0. 1.1alpha (2006-06-27) ===================== Features added -------------- * Module level ``iterwalk()`` function as 'iterparse' for trees * Module level ``iterparse()`` function similar to ElementTree (see documentation for differences) * Element.nsmap property returns a mapping of all namespace prefixes known at the Element to their namespace URI * Reentrant threading support in RelaxNG, XMLSchema and XSLT * Threading support in parsers and serializers: * All in-memory operations (tostring, parse(StringIO), etc.) free the GIL * File operations (on file names) free the GIL * Reading from file-like objects frees the GIL and reacquires it for reading * Serialisation to file-like objects is single-threaded (high lock overhead) * Element iteration over XPath axes: * Element.iterdescendants() iterates over the descendants of an element * Element.iterancestors() iterates over the ancestors of an element (from parent to parent) * Element.itersiblings() iterates over either the following or preceding siblings of an element * Element.iterchildren() iterates over the children of an element in either direction * All iterators support the ``tag`` keyword argument to restrict the generated elements * Element.getnext() and Element.getprevious() return the direct siblings of an element _______________________________________________ lxml-dev mailing list lxml-dev(a)codespeak.net http://codespeak.net/mailman/listinfo/lxml-dev

RELEASED Python 2.5 (release candidate 2)
by Anthony Baxter Sept. 13, 2006

Sept. 13, 2006

On behalf of the Python development team and the Python community, I'm happy to announce the second RELEASE CANDIDATE of Python 2.5. After the first release candidate a number of new bugfixes have been applied to the Python 2.5 code. In the interests of making 2.5 the best release possible, we've decided to put out a second (and hopefully last) release candidate. We plan for a 2.5 final in a week's time. This is not yet the final release - it is not suitable for production use. It is being released to solicit feedback and hopefully expose bugs, as well as allowing you to determine how changes in 2.5 might impact you. As a release candidate, this is one of your last chances to test the new code in 2.5 before the final release. *Please* try this release out and let us know about any problems you find. In particular, note that changes to improve Python's support of 64 bit systems might require authors of C extensions to change their code. More information (as well as source distributions and Windows and Universal Mac OSX installers) are available from the 2.5 website: http://www.python.org/2.5/ As of this release, Python 2.5 is now in *feature freeze*. Unless absolutely necessary, no functionality changes will be made between now and the final release of Python 2.5. The new features in Python 2.5 are described in Andrew Kuchling's What's New In Python 2.5. It's available from the 2.5 web page. Amongst the language features added include conditional expressions, the with statement, the merge of try/except and try/finally into try/except/finally, enhancements to generators to produce a coroutine kind of functionality, and a brand new AST-based compiler implementation. New modules added include hashlib, ElementTree, sqlite3, wsgiref, uuid and ctypes. In addition, a new profiling module "cProfile" was added. Enjoy this new release, Anthony Anthony Baxter anthony(a)python.org Python Release Manager (on behalf of the entire python-dev team)

ANN: pyXSD 0.1 released
by Karl Norby Sept. 12, 2006

Sept. 12, 2006

pyXSD v.0.1 has been released! pyXSD is a tool to map XML and XSD (XML Schema) into Python. It can validate an XML file against an XSD file. It also contains a feature to allow users to easily transform an XML file, using small python classes that are easy to use and are easy and fast for users to write. The program uses a simple, non-DOM interface in the "transforms" with the XML data tree. It can be used as a library or command-line program. The program includes a decent amount of documentation on how to use the program and on how to use and write transforms. A more thorough description of its functionality and features can be found on the projects website: http://pyxsd.org/ The program was designed for material science modeling applications, so some of the included "transform" classes are for this specific use. The program includes more general "transforms" and "transform" libraries to assist users write these classes. The program uses ElementTree and cElementTree (the ElementTree and cElementTree included in python 2.5 should work), and requires Python 2.3 or greater.
