- lxml is a Pythonic, mature 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 more.
- To contact the project, go to the `project home page
- <http://lxml.de/>`_ or see our bug tracker at
- https://launchpad.net/lxml
- In case you want to use the current in-development version of lxml,
- you can get it from the github repository at
- https://github.com/lxml/lxml . Note that this requires Cython to
- build the sources, see the build instructions on the project home
- page. To the same end, running ``easy_install lxml==dev`` will
- install lxml from
- https://github.com/lxml/lxml/tarball/master#egg=lxml-dev if you have
- an appropriate version of Cython installed.
- After an official release of a new stable series, bug fixes may become
- available at
- https://github.com/lxml/lxml/tree/lxml-3.8 .
- Running ``easy_install lxml==3.8bugfix`` will install
- the unreleased branch state from
- https://github.com/lxml/lxml/tarball/lxml-3.8#egg=lxml-3.8bugfix
- as soon as a maintenance branch has been established. Note that this
- requires Cython to be installed at an appropriate version for the build.
- 3.8.0 (2017-06-03)
- ==================
- Features added
- --------------
- * ``ElementTree.write()`` has a new option ``doctype`` that writes out a
- doctype string before the serialisation, in the same way as ``tostring()``.
- * GH#220: ``xmlfile`` allows switching output methods at an element level.
- Patch by Burak Arslan.
- * LP#1595781, GH#240: added a PyCapsule Python API and C-level API for
- passing externally generated libxml2 documents into lxml.
- * GH#244: error log entries have a new property ``path`` with an XPath
- expression (if known, None otherwise) that points to the tree element
- responsible for the error. Patch by Bob Kline.
- * The namespace prefix mapping that can be used in ElementPath now injects
- a default namespace when passing a None prefix.
- Bugs fixed
- ----------
- * GH#238: Character escapes were not hex-encoded in the ``xmlfile`` serialiser.
- Patch by matejcik.
- * GH#229: fix for externally created XML documents. Patch by Theodore Dubois.
- * LP#1665241, GH#228: Form data handling in lxml.html no longer strips the
- option values specified in form attributes but only the text values.
- Patch by Ashish Kulkarni.
- * LP#1551797: revert previous fix for XSLT error logging as it breaks
- multi-threaded XSLT processing.
- * LP#1673355, GH#233: ``fromstring()`` html5parser failed to parse byte strings.
- Other changes
- -------------
- * The previously undocumented ``docstring`` option in ``ElementTree.write()``
- produces a deprecation warning and will eventually be removed.
