I haven't seen any crashes with Regex - but of course that doesn't mean 
they can't happen :-)

But the regex I sent certainly does work with line breaks.

Actually, it's not infallible. It would fail on Eric's code for the same 
reason my first try did. He has javascript code which can contain "<" or 
">", so the regex exits half-way through the "comment" that contains the 
javascript source code.

Easy to fix in your offset scheme (and probably easy to fix in regex as 
well, but I don't know how to do it yet).
Time to read some more about regex ...
