I guess I'm in a posting mood today. I worked up a
quick class that wraps the the DOM node output from
getContentAsDOM method. The class simple takes a
ResourceSet in its construtor and will return an DOM
Document, DOM4J Document, or XML as a String. Feel
free to use it, and if folks like it enough I'll add a
few more features and put it on my website for
download.
