Nokogiri (鋸) is an HTML, XML, SAX, and Reader parser. Among Nokogiri's many features is the ability to search documents via XPath or CSS3 selectors.
XML is like violence - if it doesn’t solve your problems, you are not using enough of it.
XPath support for document searching
CSS3 selector support for document searching

Nokogiri also features an Hpricot compatibility layer to help ease the change to using correct CSS and XPath.
