If you're going to do XPath queries, and not CSS selector queries,
I'd recommend just using straight DOM -- it provides one less layer of
abstraction, and will get you all the DOM objects you'd normally expect.

Zend_Dom_Query returns a Zend_Dom_Query_Result object, which proxies a
DOMNodeList. If you iterate through it, you'll get individual DOMNode
objects, and you can also retrieve the DOMDocument using the
getDocument() method.
