Thanks...I knew there was a simple way of doing this...I was over complicating it!! :) I'm probably going to have lots more questions to post on this board, hopefully ones that aren't so easy.
P.S. Anyone recommend a good regex editor? I installed a trial version of regex buddy on Vista and after the first use, it got corrupted! Any freeware out there?
For matches such as these, if some of your alternatives are extensions of other (i.e. U.S. Virgin Islands contains U.S. and then some more text) you always need to put the longer one first, so it will attempt to match that one first.
