Hey, thanks. But duh ;)
that's why the macro I just released actually works.
I gave up on regex finally and mangled HTML around a bit to work with
the normal select brackets internal TextMate command.
I was fiddling around with recursive regex, but it seems to completely
crash TextMate if you don't have it just right, so it's extremely hard
to play with.
