CSS3 not selector #205

Yes, this looks like a bug. :-( I believe the CSS parser is accepting this string, but translating it to the wrong XPath. I will investigate |

Updating with the CSS spec reference: |

I'm having this problem as well. Would be swell if it were fixed :) Doesn't seem like there is a function to support "not". |

I am trying to use the :not() selector of CSS3 to filter out the first list item from an unordered list.
When I run this code however, I run into an error "RuntimeError: xmlXPathCompOpEval: function first-child not found"
d = Nokogiri::HTML.parse('<html><body><ul><li id="1">1</li><li id="2">2</li><li id="3"<3</li></ul></body></html>')
d.css('ul li:not(:first-child)')
I have tried changing the CSS selector as follows, and got some strange results:
d.css('ul li:not(#2)') # works
d.css('ul li:not(li)') # fails with error Nokogiri::CSS::SyntaxError: unexpected 'li' after ':not('
d.css('ul li:not(:last-child)') # fails with the same original error of function last-child not found
I believe that according to the spec at http://www.w3.org/TR/css3-selectors/#pseudo-classes, these CSS3 selectors should work?
Any help would be appreciated.
