(I would prefer a string solution to this, or something built into the PHP library, and not some big package I have to install.)

I have a string which consists of potentially bad XML.

I have a tag <mytag> which may exist in the XML multiple times.

I want to return the text contained in first instance of <mytag>, or the empty string if it doesn't exist. So in the following instance:
php:
<?
<html>
<mytag>THIS_IS_THE_STRING</mytag>
<span>aaaaaa</span>
<html>
?>
I want to yank out the string "THIS_IS_THE_STRING"

Is there something that already does this or do I have to write it myself?

From the looks of it, you are parsing HTML which in a lot of cases can be malformed. A great extension for helping with that though is Tidy as it can cleanup and repair broken elements.

SimpleXML is a nice interface but you also have the option of using the DOM interface for interacting with XML/HTML which can sometimes give a little more flexibility. I find myself using XPath a lot for pulling content out of HTML.
