Open source html parser supporting xpath?

[softtouch 9]

Does anybody know of an open source html parser which support xpath expressions and can parse the html content from a string or stream?

I tried the HtmlParserEx from https://github.com/radprogrammer/htmlparser but it only understand simple xpath expressions like //*[@class="description"] but does not work properly using //*[@class="description" and contains(text(),"whatever")] (returning wrong data)

XPath parses only XML. You can't use XPath to parse plain HTML.  It can parse XHTML, which is HTML using XML syntax.
