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.
