cssselect

It can read CSS 3 selectors and virtually transform them to XPath 1.0 compatible expressions.

The code was part of the lxml Python module as lxml.cssselect.

Now it can work as a stand-alone.

Features:

• Supported selectors:
• :hover
• :active
• :focus
• :target
• :visited

What is new in this release:

• Added parser support for :attr:`functional pseudo-elements <Selector.pseudo_element>`.

What is new in version 0.7.1:

• 0.7 broke the parser in Python 2.4 and 2.5; the tests in 2.x. Now all is well again.

What is new in version 0.6:

• In ``setup.py`` use setuptools/distribute if available, but fall back on distutils.
• Implement the ``:lang()`` pseudo-class, although it is only based on ``xml:lang`` or ``lang`` attributes. If the document language is known from some other meta-data (like a ``Content-Language`` HTTP header or ``<meta>`` element), a workaround is to set a lang attribute on the root element.

What is new in version 0.5:

• Fix case sensitivity issues.
• Implement :class:`HTMLTranslator` based on the `HTML5 specification`_ rather than guessing; add the ``xhtml`` parameter.
• Several bug fixes and better test coverage.

Requirements:

• Python 2.4 or higher
