How to find a newline in preg replace?

[willybfriendly]

Has to be simple, but I am not getting this right.

So, how to I test for newline(s) in a preg_replace()?

Trying to clean up some poor code in a CMS. I have this, which works:

$pattern = '{<h1>[ *]<a href(.*)</a>[ *]</h1>}'; 
$replacement = '<h2><a href$1</a></h2>'; 
$string = '<h1><a href="http://localhost/folder/file.htm" class="class">Title</a></h1></td>'; 
$ntext=preg_replace($pattern, $replacement, $string); 

Problem is that there can be an unknown number of spaces and/or newlines between <h1> and <a... and also between </a> and </h1>

I can test for the spaces, but have been unable to get the test for a newline to work. Have tried \n without success.

BTW, don't ask why I am doing this rather than hacking the CMS code. This really is an easier way on this one ;)

you can cover spaces and newlines etc with \s flag.
