Hi
Thanks for all the responses guys... really helpful stuff
I'll definitely be reading more about these tricky (yet amazingly useful)
little blighters :)
It's nice to have some support where people know what you are talking
about... a relatively unknown concept for me :)
Cheers
Dan

Hi Dan,
The trick, I've found, to making a robust regex for matching HTML is to go
back to the RFC and build it in totality. Using ColdFusion's version of
Regex (which uses slightly different tokens than most regex's) I did this a
while back. The resulting regex can be used to find all sorts of variations
on tags.
Take a look here if you are interested:
