Yes, Atom is written in XML. As for your XPath expression, I haven't followed the whole thing but you're going to run into the problem where XPath 1.0 can't find elements with names in the default namespace. You would have to define a namespace context for the URI of the default namespace and assign it a prefix, then use that prefix in your XPath expression.
