in reply to Big, bad, ugly regex problem
A couple of comments. Use a HTML Parser if at all possible.
Your brane will thank you in the long run. I think
someone has already suggested that. Apart from that though
so far I can only see one thing wrong with the regex. You
specify an optional open quote with \3 and an optional close
quote matching \3 but in between you use \3 with a negative
lookahead and for the times when there isn't a \3 bad stuff
will happen. I'm not sure really what will happen. IIRC these
catch variables are guaranteed to be undefined when you
start a new match or substitution.
