quick regex help

I have an html page that I loaded into a variable ($page) via cURL, and I need to extract a piece of information from it.

There is a tag such as:
<h2 class="yxz">MY TEXT</h2>

And I want to extract the 'my text' inside the tag.

There is only going to be one of such tags on the page, so I used strpos to get the location of the opening tag, and then str_replace to cut everything out before the tag. But the amount of text inside the tag is a variable length, and I am having trouble extracting it.

I now have a string ($str) that looks like:
SOME TEXT HERE </h2> ....

I tried using the regex: /[^<]+/ (greedily select any number of characters that isn't a '<' ) with preg_split to get everything before the </h2>, but I can't seem to get it working.

Thanks.

And I realize that this can be done without a regular expression, but I need to learn how to work regex within php.

 

Is this always going to be <h2 class="yxz">?

Or can the class name change?

 

Use this pattern to find any <h2> tag

<?php
$pattern = "(<h2[^>]*?>([^<]*?)</h2>)";
$valid = preg_match($pattern, $data, $SEARCH);

if ($valid) {
	echo $SEARCH[1];
}
?>

PHP:

.. and this pattern for specific h2.class name. (eg. yxz)

<?php
$pattern = "(<h2[^>]*?class=\"yxz\">([^<]*?)</h2>)";
$valid = preg_match($pattern, $data, $SEARCH);

if ($valid) {
	echo $SEARCH[1];
}
?>
