An HTML, XML, SAX and Reader parser for Ruby with the ability to search documents via XPath or CSS3 selectors… and much more

Nokogiri (鋸) is an HTML, XML, SAX and Reader parser for Ruby. Among Nokogiri’s many features is the ability to search documents via XPath or CSS3 selectors.

From the Nokogiri readme:

XML is like violence - if it doesn’t solve your problems, you are not using enough of it.
