Easy: It's called "greedy matching," and every regex engine does it.
That's where I thought maybe something like a lookahead or lookbehind
might come in handy, because you can say something like:
<div, then a </div, without another </div before it
As for your other comments, I'll re-read and see if a thought is born.
