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.
