Regular Expressions to match HTML

[Sebarry]

Hi,

I have a need to read an HTML file into an array and match certain sections of it. I want to be able to extract headers and text within certain DIV tags with a class of padding8. For example,

I want to be able to match this

<div class="bottomPostionDiv" ><h1 >PROFESSIONAL </h1></div>

But not this because there's no content.

<div class="bottomPostionDiv" ><h1 ></h1></div>

.

I want to extract the content of this DIV.

<div class="padding8">
<h2>Who does it apply to?</h2>
Professional Development is relevant to all members, although<br>
Corporate Members are required by the Code of Professional<br>
Development to:<br>
<span class="colorBlueLight">&bull;</span> Be committed to continuous learning and improvement<br>
<span class="colorBlueLight">&bull;</span> Take ownership of their development and maintain it in a systematic manner<br>
<span class="colorBlueLight">&bull;</span> Support the learning and development of others
</div>
 

and this

<div class="colOne width210">
<h4 >Professional Development
is a process that enables
you to maintain and
develop relevant skills and
knowledge throughout your career</h4>
<!-- end of h4 -->
</div><!-- end of colOne 2-->
 

I have tried using preg_replace and eregi, not sure which is best.

$delimiters['/<h{1}>/'] = '/</h{1}/';
$delimiters['/class = "colOne \w">\s<h/'] = '/<\/div>/';
$delimiters['/padding8/'] = '/<\/div>/';
$delimiters['/block22/'] = '/<\/div>/';
 

Please help.
