Regex Problem (:

I'm trying to do a match on a line from a page. At the moment I have;

$page_info =~ m,\<td\>\<font face=(.+?) size=(.+?)\>\&nbsp\;(.+?)\<\/td\>,i and $ID = $3;

The problem is, right after the 3rd (.+?) I have a </a>....however, this is not present on all the entries grabbed. I've tried doing stuff like this after it;

(\<\/a>?)

and severa lother combinations...however, none of them seem to work :-/ If I take out that code, and simply grab links that don't have the </a> in it, the regex works fine. I've never claimed to be great at regex....and I'm pretty stumped here Unsure

Cheers

Mmm have you taken the time to read "perlre" at perldoc.com?

You don't need to escape all the stuff you've escaped in that regex. You only escape meta-characters.

Using "and $ID = $3" at the end is also a bit obscure Crazy

Code:
my ($ID) = $page_info =~ m,<td><font face=[^\s]+ size=[^>]+>&nbsp;(.+?)(?:</a>)?</td>,si

Try something like that. It can probably still be improved.

(a-z)? probably wasn't what you were thinking of ;)
