This is what I have at the moment.

<h2>header</h2>\n   +<p>(.*)<br />|</p>
                  ^ that is a tab space, didn't know if there was
 a better way to represent one or more (it seems to work)

Im trying to match the 'bla bla.' text, but my current regex doesn't quite work, it will match most of the line, but I want it to match the first

<h2>Information</h2>
    <p>bla bla.<br /><br /><a href="http://www.google.com">google</a><br />

or

<h2>Information</h2>
    <p>bla bla.</p> other code...

Oh and my php code:

    preg_match('#h2>header</h2>\n   +<p>(.*)<br />|</p>#', $result, $postMessage);
