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:
