+A quick test of tokenizing:
+
+ >>> from lxml.html.css import tokenize, parse
+ >>> def ptok(s):
+ ... for item in tokenize(s):
+ ... print repr(item)
+ >>> ptok('E > f[a~="y\\"x"]')
+ Symbol(u'E', 0)
+ Token(u'>', 2)
+ Symbol(u'f', 4)
+ Token(u'[', 5)
+ Symbol(u'a', 6)
+ Token(u'~=', 7)
+ String(u'y"x', 9)
+ Token(u']', 15)
+
+Then of parsing:
+
+ >>> parse('div, td.foo, div.bar span')
+ Or([Element[div], Class[Element[td].foo], CombinedSelector[Class[Element[div].bar] <followed> Element[span]]])
+ >>> parse('div > p')
+ CombinedSelector[Element[div] > Element[p]]
+ >>> parse('td:first')
+ Pseudo[Element[td]:first]
+ >>> parse('a[name]')
+ Attrib[Element[a][name]]
+ >>> parse('a[rel="include"]')
+ Attrib[Element[a][rel = String(u'include', 6)]]
+ >>> parse('a[hreflang |= \'en\']')
+ Attrib[Element[a][hreflang |= String(u'en', 14)]]
+ >>> parse('div:nth-child(10)')
+ Function[Element[div]:nth-child(10)]
+ >>> parse('div:nth-of-type(10)')
+ Function[Element[div]:nth-of-type(10)]
+ >>> parse('label:only')
+ Pseudo[Element[label]:only]
+ >>> parse('a:lang(fr)')
+ Function[Element[a]:lang(Element[fr])]
+ >>> parse('div:contains("foo")')
+ Function[Element[div]:contains(String(u'foo', 13))]
+ >>> parse('div#foobar')
+ Hash[Element[div]#foobar]
+ >>> parse('div:not(div.foo)')
+ Function[Element[div]:not(Class[Element[div].foo])]
+ >>> parse('td ~ th')
+ CombinedSelector[Element[td] ~ Element[th]]
+
+Now of translation:
+
+ >>> def xpath(css):
+ ... print parse(css).xpath()
+ >>> xpath('*')
+ *
+ >>> xpath('E')
+ e
+ >>> xpath('E[foo]')
+ e[@foo]
+ >>> xpath('E[foo="bar"]')
+ e[@foo = 'bar']
+ >>> xpath('E[foo~="bar"]')
+ e[contains(concat(' ', normalize-space(@foo), ' '), ' bar ')]
+ >>> xpath('E[foo^="bar"]')
+ e[starts-with(@foo, 'bar')]
+ >>> xpath('E[foo$="bar"]')
+ e[substring(@foo, string-length(@foo)-2) = 'bar']
+ >>> xpath('E[foo*="bar"]')
+ e[contains(@foo, 'bar')]
+ >>> xpath('E[hreflang|="en"]')
+ e[@hreflang = 'en' or starts-with(@hreflang, 'en-')]
+ >>> #xpath('E:root')
+ >>> xpath('E:nth-child(1)')
+ */e[0]
+ >>> xpath('E:nth-last-child(1)')
+ */e[last() - 0]
+ >>> xpath('E:nth-of-type(1)')
+ */e[0]
+ >>> xpath('E:nth-last-of-type(1)')
+ */e[last() - 0]
+ >>> xpath('E:first-child')
+ */e[position() = 0]
+ >>> xpath('E:last-child')
+ */e[position() = last()]
+ >>> xpath('E:first-of-type')
+ */e[0]
+ >>> xpath('E:last-of-type')
+ e[last()]
+ >>> xpath('E:only-child')
+ e[count(..) = 1]
+ >>> xpath('E:only-of-type')
+ e[count(../node-name(.)) = 1]
+ >>> xpath('E:empty')
+ e[count(.) = 0 and string(.) = '']
+ >>> xpath('E:contains("foo")')
+ e[contains(css:lower-case(string(.)), 'foo')]
+ >>> xpath('E.warning')
+ e[contains(concat(' ', normalize-space(@class), ' '), ' warning ')]
+ >>> xpath('E#myid')
+ e[@id='myid']
+ >>> xpath('E:not(:contains("foo"))')
+ e[not(contains(css:lower-case(string(.)), 'foo'))]
+ >>> xpath('E F')
+ e/descendant::f
+ >>> xpath('E > F')
+ e/f
+ >>> xpath('E + F')
+ e/following-sibling::f[0]
+ >>> xpath('E ~ F')
+ e/following-sibling::f
+ >>> xpath('div#container p')
+ div[@id='container']/descendant::p
