Usage::
>>> from lxml import etree, cssselect
>>> select = cssselect.CSSSelector("a tag > child")
>>> root = etree.XML("<a><b><c/><tag><child>TEXT</child></tag></b></a>")
>>> [ el.tag for el in select(root) ]
['child']
To use CSS namespaces, you need to pass a prefix-to-namespace
mapping as ``namespaces`` keyword argument::
>>> rdfns = 'http://www.w3.org/1999/02/22-rdf-syntax-ns#'
>>> select_ns = cssselect.CSSSelector('root > rdf|Description',
... namespaces={'rdf': rdfns})
>>> rdf = etree.XML((
... '<root xmlns:rdf="%s">'
... '<rdf:Description>blah</rdf:Description>'
... '</root>') % rdfns)
>>> [(el.tag, el.text) for el in select_ns(rdf)]
[('{http://www.w3.org/1999/02/22-rdf-syntax-ns#}Description', 'blah')]
