I've learned XML/XSD piecemeal. I feel like I need to start over at the
beginning sometimes to fill in all of the knowledge holes. Anyone have a
good resource to do this?
In any case, I've attached a file that has two pieces of my code. I can
give you all more if it will help. I'll look at your suggestions. Thanks
for mentioning XML Notepad too. I'll put that utility through it's paces.
Thanks again guys!
