.. :changelog:
History
-------
1.6.0 (2020-05-07)
~~~~~~~~~~~~~~~~~~
* Python 3.4 is no longer supported
* New ``Selector.remove()`` and ``SelectorList.remove()`` methods to remove
selected elements from the parsed document tree
* Improvements to error reporting, test coverage and documentation, and code
cleanup
1.5.2 (2019-08-09)
~~~~~~~~~~~~~~~~~~
* ``Selector.remove_namespaces`` received a significant performance improvement
* The value of ``data`` within the printable representation of a selector
(``repr(selector)``) now ends in ``...`` when truncated, to make the
truncation obvious.
* Minor documentation improvements.
1.5.1 (2018-10-25)
~~~~~~~~~~~~~~~~~~
* ``has-class`` XPath function handles newlines and other separators
in class names properly;
* fixed parsing of HTML documents with null bytes;
* documentation improvements;
* Python 3.7 tests are run on CI; other test improvements.
1.5.0 (2018-07-04)
~~~~~~~~~~~~~~~~~~
* New ``Selector.attrib`` and ``SelectorList.attrib`` properties which make
it easier to get attributes of HTML elements.
* CSS selectors became faster: compilation results are cached
(LRU cache is used for ``css2xpath``), so there is
less overhead when the same CSS expression is used several times.
* ``.get()`` and ``.getall()`` selector methods are documented and recommended
over ``.extract_first()`` and ``.extract()``.
* Various documentation tweaks and improvements.
One more change is that ``.extract()`` and ``.extract_first()`` methods
are now implemented using ``.get()`` and ``.getall()``, not the other
way around, and instead of calling ``Selector.extract`` all other methods
now call ``Selector.get`` internally. It can be **backwards incompatible**
in case of custom Selector subclasses which override ``Selector.extract``
without doing the same for ``Selector.get``. If you have such Selector
subclass, make sure ``get`` method is also overridden. For example, this::
class MySelector(parsel.Selector):
def extract(self):
return super().extract() + " foo"
should be changed to this::
class MySelector(parsel.Selector):
def get(self):
return super().get() + " foo"
extract = get
1.4.0 (2018-02-08)
~~~~~~~~~~~~~~~~~~
* ``Selector`` and ``SelectorList`` can't be pickled because
pickling/unpickling doesn't work for ``lxml.html.HtmlElement``;
parsel now raises TypeError explicitly instead of allowing pickle to
silently produce wrong output. This is technically backwards-incompatible
if you're using Python < 3.6.
1.3.1 (2017-12-28)
~~~~~~~~~~~~~~~~~~
* Fix artifact uploads to pypi.
1.3.0 (2017-12-28)
~~~~~~~~~~~~~~~~~~
* ``has-class`` XPath extension function;
* ``parsel.xpathfuncs.set_xpathfunc`` is a simplified way to register
XPath extensions;
* ``Selector.remove_namespaces`` now removes namespace declarations;
* Python 3.3 support is dropped;
* ``make htmlview`` command for easier Parsel docs development.
* CI: PyPy installation is fixed; parsel now runs tests for PyPy3 as well.
1.2.0 (2017-05-17)
~~~~~~~~~~~~~~~~~~
* Add ``SelectorList.get`` and ``SelectorList.getall``
methods as aliases for ``SelectorList.extract_first``
and ``SelectorList.extract`` respectively
* Add default value parameter to ``SelectorList.re_first`` method
* Add ``Selector.re_first`` method
* Add ``replace_entities`` argument on ``.re()`` and ``.re_first()``
to turn off replacing of character entity references
* Bug fix: detect ``None`` result from lxml parsing and fallback with an empty document
* Rearrange XML/HTML examples in the selectors usage docs
* Travis CI:
* Test against Python 3.6
* Test against PyPy using "Portable PyPy for Linux" distribution
1.1.0 (2016-11-22)
~~~~~~~~~~~~~~~~~~
* Change default HTML parser to `lxml.html.HTMLParser <http://lxml.de/api/lxml.html.HTMLParser-class.html>`_,
which makes easier to use some HTML specific features
* Add css2xpath function to translate CSS to XPath
* Add support for ad-hoc namespaces declarations
* Add support for XPath variables
* Documentation improvements and updates
1.0.3 (2016-07-29)
~~~~~~~~~~~~~~~~~~
* Add BSD-3-Clause license file
* Re-enable PyPy tests
* Integrate py.test runs with setuptools (needed for Debian packaging)
* Changelog is now called ``NEWS``

* Added docstrings and other doc fixes
1.0.1 (2015-08-24)
