Yep, thanks for pointing that out, and indeed my XML does contain CDATA.
By default QDomNode::nodeName() returns "#cdata" in those cases, which
might actually be ok for what I'm doing. I guess for completeness I should
handle that and allow the user to see it since my goal is to just have the user
be able to review the original XML within my app.

I definitely did that to build up the internal data tree hierarchy to populate the
model, and that was invaluable. Now it's just tweaking strings to get the view
to look just how I want it.
