If you're using php5 you can use DOM's getElementsByTagName.

If you still think you need to do some sort of regex it is possible
but it will be buggy at best.

Nope, need a regex... guess I have no choice, either chancy regex or nothing... I know for a fact that the first paragraph tag wont contain a class, and for the <p> tags that contain a class="blah" does it matter that i know exactly what the classname is?

preg_match_all('|<p[^>]*>(.*)</p>|Ui', $myText, $myArray);

$tag_regex=array(
'/\<p(\s*)\>(.*?)\<\/p\> /si' => "$1",
'/\<(\s*)(*.?)class\=(*.?)\>(.*?)\<\/(*.?)\>/si' => "$3"
);

$paragraphs=preg_replace(array_keys($tag_regex),ar ray_values($tag_regex),$page);

I am not sure what tag is that you mean on <class="something">, but in this
RE .. it should capture any <p> tags (the first element of the array) and
any tags (the second element of the array) that has attribute class on it.

You can find another example of this kind of HTML parsing in the PHP... try
googling it..:)
