I think my problem is that my tree has a hell of a lot
of "children" that aren't what I expect them to be. They
seem to be text nodes with end-of-line strings or some
damn thing in them. I don't know where the hell they
come from. :-(
Once I realized this, and threw these objects out,
I had no difficulty traversing the tree and building
a set of structures and corresponding widgets to change
the values. Now I'm trying to figure out how to put
the values back in the XML file without having to completely
re-write the file.
Cheers,
David
