Parse not-well formed html on iphone (+XPath?)

I have to parse an HTML which is not well-formed.

I want to use XPath to retrieve some elements.

What could I use on i开发者_JS百科phone?

libxml2 and the function PerformHTMLXPathQuery by Marcus Zarra. See http://cocoawithlove.com/2008/10/using-libxml2-for-parsing-and-xpath.html
