I do that with a somewhat-inelegant hack that uses chunked parsing,
and simply stops stops feeding chunks to the parser when it's found
what I'm looking for.  That means only a small amount of extra
parsing will happen.

Yep, that's also useful.  Though the effect is fairly negligible,
unless your callbacks do some heavyweight processing.

That's something I hadn't seen.  Is it a newish call?  Is it available
in the htmlParser?
