Hi Gilles,

I'm not a regex guru, but I can see a spot a couple problem areas in
your expression:

1. The core syntax could probably be simplified using something like
this:

|^<title>([^<]+)</title>$|i

I hope I got that right -- I usually have to test my expression a few
times before I get all the nuances right. :)

2. smiU - That's modifier overkill. The U here and the ? in your
expression are probably reacting to each other in unexpected ways. If
you don't know about this page, it can help:

http://www.php.net/manual/en/reference.pcre.pattern.modifiers.php

I have a prefab function I've used for this very thing, but
unfortunately I don't have access to it that moment. Hopefully,
someone will be along shortly with the proper syntax. In the
meantime, I hope this helps in a more general sense.

Regards,
Tom
