Hey everyone! Have you finished your holiday shopping yet? I know I haven't.
Fortunately for you guys, Mike and I like programming a lot more than
shopping. I mean, don't get me wrong. I *love* shopping for myself, I
just find shopping for other people to be, well, difficult.
Anyway, let's get down to business:
nokogiri version 1.4.1 has been released!

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.
