-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2011-5699 2011-04-21 02:56:37 --------------------------------------------------------------------------------
Name : python-lxml Product : Fedora 15 Version : 2.3 Release : 1.fc15 URL : http://codespeak.net/lxml/ Summary : ElementTree-like Python bindings for libxml2 and libxslt Description : lxml provides a Python binding to the libxslt and libxml2 libraries. It follows the ElementTree API as much as possible in order to provide a more Pythonic interface to libxml2 and libxslt than the default bindings. In particular, lxml deals with Python Unicode strings rather than encoded UTF-8 and handles memory management automatically, unlike the default bindings. -------------------------------------------------------------------------------- Update Information: 2.3 (2011-02-06) ================ Features added -------------- * When looking for children, ``lxml.objectify`` takes '{}tag' as meaning an empty namespace, as opposed to the parent namespace. Bugs fixed ---------- * When finished reading from a file-like object, the parser immediately calls its ``.close()`` method. * When finished parsing, ``iterparse()`` immediately closes the input file. * Work-around for libxml2 bug that can leave the HTML parser in a non-functional state after parsing a severly broken document (fixed in libxml2 2.7.8). * ``marque`` tag in HTML cleanup code is correctly named ``marquee``. Other changes -------------- * Some public functions in the Cython-level C-API have more explicit return types. 2.3beta1 (2010-09-06) ===================== Features added -------------- Bugs fixed ---------- * Crash in newer libxml2 versions when moving elements between documents that had attributes on replaced XInclude nodes. * ``XMLID()`` function was missing the optional ``parser`` and ``base_url`` parameters. * Searching for wildcard tags in ``iterparse()`` was broken in Py3. * ``lxml.html.open_in_browser()`` didn't work in Python 3 due to the use of os.tempnam. It now takes an optional 'encoding' parameter. Other changes -------------- 2.3alpha2 (2010-07-24) ====================== Features added -------------- Bugs fixed ---------- * Crash in XSLT when generating text-only result documents with a stylesheet created in a different thread. Other changes -------------- * ``repr()`` of Element objects shows the hex ID with leading 0x (following ElementTree 1.3). 2.3alpha1 (2010-06-19) ====================== Features added -------------- * Keyword argument ``namespaces`` in ``lxml.cssselect.CSSSelector()`` to pass a prefix-to-namespace mapping for the selector. * New function ``lxml.etree.register_namespace(prefix, uri)`` that globally registers a namespace prefix for a namespace that newly created Elements in that namespace will use automatically. Follows ElementTree 1.3. * Support 'unicode' string name as encoding parameter in ``tostring()``, following ElementTree 1.3. * Support 'c14n' serialisation method in ``ElementTree.write()`` and ``tostring()``, following ElementTree 1.3. * The ElementPath expression syntax (``el.find*()``) was extended to match the upcoming ElementTree 1.3 that will ship in the standard library of Python 3.2/2.7. This includes extended support for predicates as well as namespace prefixes (as known from XPath). * During regular XPath evaluation, various ESXLT functions are available within their namespace when using libxslt 1.1.26 or later. * Support passing a readily configured logger instance into ``PyErrorLog``, instead of a logger name. * On serialisation, the new ``doctype`` parameter can be used to override the DOCTYPE (internal subset) of the document. * New parameter ``output_parent`` to ``XSLTExtension.apply_templates()`` to append the resulting content directly to an output element. * ``XSLTExtension.process_children()`` to process the content of the XSLT extension element itself. * ISO-Schematron support based on the de-facto Schematron reference 'skeleton implementation'. * XSLT objects now take XPath object as ``__call__`` stylesheet parameters. * Enable path caching in ElementPath (``el.find*()``) to avoid parsing overhead. * Setting the value of a namespaced attribute always uses a prefixed namespace instead of the default namespace even if both declare the same namespace URI. This avoids serialisation problems when an attribute from a default namespace is set on an element from a different namespace. * XSLT extension elements: support for XSLT context nodes other than elements: document root, comments, processing instructions. * Support for strings (in addition to Elements) in node-sets returned by extension functions. * Forms that lack an ``action`` attribute default to the base URL of the document on submit. * XPath attribute result strings have an ``attrname`` property. * Namespace URIs get validated against RFC 3986 at the API level (required by the XML namespace specification). * Target parsers show their target object in the ``.target`` property (compatible with ElementTree). Bugs fixed ---------- * API is hardened against invalid proxy instances to prevent crashes due to incorrectly instantiated Element instances. * Prevent crash when instantiating ``CommentBase`` and friends. * Export ElementTree compatible XML parser class as ``XMLTreeBuilder``, as it is called in ET 1.2. * ObjectifiedDataElements in lxml.objectify were not hashable. They now use the hash value of the underlying Python value (string, number, etc.) to which they compare equal. * Parsing broken fragments in lxml.html could fail if the fragment contained an orphaned closing '</div>' tag. * Using XSLT extension elements around the root of the output document crashed. * ``lxml.cssselect`` did not distinguish between ``x[attr="val"]`` and ``x [attr="val"]`` (with a space). The latter now matches the attribute independent of the element. * Rewriting multiple links inside of HTML text content could end up replacing unrelated content as replacements could impact the reported position of subsequent matches. Modifications are now simplified by letting the ``iterlinks()`` generator in ``lxml.html`` return links in reversed order if they appear inside the same text node. Thus, replacements and link-internal modifications no longer change the position of links reported afterwards. * The ``.value`` attribute of ``textarea`` elements in lxml.html did not represent the complete raw value (including child tags etc.). It now serialises the complete content on read and replaces the complete content by a string on write. * Target parser didn't call ``.close()`` on the target object if parsing failed. Now it is guaranteed that ``.close()`` will be called after parsing, regardless of the outcome. Other changes ------------- * Official support for Python 3.1.2 and later. * Static MS Windows builds can now download their dependencies themselves. * ``Element.attrib`` no longer uses a cyclic reference back to its Element object. It therefore no longer requires the garbage collector to clean up. * Static builds include libiconv, in addition to libxml2 and libxslt. -------------------------------------------------------------------------------- References: [ 1 ] Bug #671908 - can not import lxml.etree in python3 (ValueError: All strings must be XML compatible) https://bugzilla.redhat.com/show_bug.cgi?id=671908 [ 2 ] Bug #675615 - python-lxml-2.3 is available https://bugzilla.redhat.com/show_bug.cgi?id=675615 [ 3 ] Bug #688418 - [abrt] radiotray-0.6.3-2.fc15: lxml.objectify.pyx:1372:lxml.objectify._setupPickle (src/lxml/lxml.objectify.c:15062):NameError: fromstring https://bugzilla.redhat.com/show_bug.cgi?id=688418 [ 4 ] Bug #600036 - FTBFS python-lxml-2.2.6-1.fc14 https://bugzilla.redhat.com/show_bug.cgi?id=600036 -------------------------------------------------------------------------------- This update can be installed with the "yum" update program.
