Snappy the Clam

But you can see it too: this XPath Tutorial at zvon.org is pretty damn nice, and so far, everything I've seen on this site leads me to believe that it's a great reference site for all sorts of XML-related technologies. But then again, you probably knew that already, right? Sure you did. I'm particularly interested in what exactly XLab is (see the examples in the tutorial), but the whole site just smells like smart innovative competence.
