Reg Expression Question

[rgraves]

Hi,

I'm writing a regular expression that will search for specific <a href> tags and modify the URL within them. Here is what I have:

$mytxt = preg_replace("!(<td class=\"helptoc-question\"><a href=\"http://www.mydomain.com/page.html#[0-9]\">)(.)(</a></td>)!", "!(<a href=\"#[0-9]\">)(.)(</a></td>)!", $_POST['txt']);

Basically, it removes everything in the URL before the # mark and keeps everything else (including the text in between the <a></a> tag). I don't believe there is a spacing issue so ignore that if there appears to be spaces when I post this thread.

Any help would be much appreciated.

$mytxt = preg_replace('§(<a href="http://www.mydomain.com/page.html)#[0-9]*(">)§i', "\1\2", $_POST['txt'])

Thanks.

This makes sense however I am getting the following PHP error:

Warning: Unknown modifier '#' in ... on line 106

Nevermind, I've figured it out.
