Any equivalent to Ruby's 'hpricot' html/xpath/css selector package?

Hpricot is a fine package but I prefer Nokogiri (see
http://www.rubyinside.com/nokogiri-ruby-html-parser-and-xml-parser-1288.html)
because it is based on libxml2 and therefore is faster, conforms to
the full XPath 1.0 spec, works on imperfect HTML, and exposes the
Hpricot API.

In python, the equivalent is lxml (http://codespeak.net/lxml/), which
is similarly based on libxml2, very fast, XPath-1.0 conformant, and
exposes the now-standard ElementTree API.

The main difference is that lxml doesn't have CSS selector syntax, but
IMHO that's a gimmick when you have a full XPath 1.0 engine at your
disposal.
