Hi John,
Why not have a class that responsible for maintaining the DOM list and
have everything else make calls into it. That way you also hide all of
the xerces specific code in case you later need to swap out with another
parser. Also, if you want to thread your code, you'll need to protect
the DOM structure and the class you build would be able to handle that.
We use something similar to this in our main app. I'd be happy to give
you more details if you wish.
