Regex to find URLs in <a> tags

Hi all,

I spent like a day working on this. Basically what I am after is regex to find all the href URLs and <a> tags, and if it contains a certain part of a URL, then replace it. It definitely has to pick up both single and double quotes.

To illustrate, take the following example:
<a id='user_link' class='' href="http://mysite.com/forums_real_path/index.php?showuser=1" title='Your Profile'Username &nbsp;<span id='user_link_dd'></span></a>

I want to use regex to change 'forums_real_path' to just 'forums'. But it must be only in <a></a> tags.

Here's the code I was using, and it was working, but for some reason it didn't work on a bunch of new links:
$replacement='<a href=$1$2forums$3$4>$5</a>';

Its kinda messy :/

If anyone could write a much better pattern for me, I'd be very grateful :)
