Hi,

Maybe the example is overkill, but I give you a quick setup that can 
save you some time finding HTML tags with a certain attribute.

<?php

$html = <<<END_OF_HTML

<b>hello</b>
<b class="blah">hello</b>
<p>hello</p>
<p class="blah">hello</p>
<a>hello</a>
<a href="url">hello</a>
END_OF_HTML;

$tags = array();
$tags[] = 'p';
$tags[] = 'a';

$tags = implode('|', $tags);

$pattern = '/<('.$tags.')[^>]*>/i';

echo $pattern."\n";

preg_match_all($pattern, $html, $matches);

var_dump($matches);

?>

I'm not an expression guru either, but I think it works OK. I had to 
find 'link', 'img', 'a' and other tags in HTML and used a more complex 
expression for it which worked like a charm.

It's just an example. For you, you have to leave away the 'a' tag in the 
$tags array, to get what you want.

Hope it helps!
