Has anyone published tools for XML DOM manipulation?

Specifically in MATLAB, if I read in an XML file, I'd like to be able to extract elements via something along the lines of css selectors. Does such a thing exist?

Not sure if this is what you're looking for, but I just posted a tool for selecting XML data using XPath.

There are also some blog posts on mathworks.com about using Java to navigate the DOM.
