Using the text exactly as above it wouldn't work because the patterns you're
searching for have newlines in the middle of them.  Changing either the
compiled pattern or the text works fine for Python 2.1 on Linux.

You probably don't want to hear people saying that this is a really hairy way
of parsing HTML anyway or talking about htmllib etc. but this is the sort of
reason why it's better to do it 'properly' :)
