Thanks Peter. I'll try that first thing Monday morning when I'm back
to work. It
is a totally different approach than what I was trying with regex.

And Shawn, I didn't post any of my work because the network I work on
isn't
connected to the internet. So it didn't seem constructive to re-type
all of my
failed code just to satisfy your "standards" of proving that I've been
trying to
hack this myself for the past few days. All in all, thanks for your,
uhhhh,
constructive comments.
