It's a unit test showing how you can use SimpleXML to do what you want.
It's written for Testilence out of sheer laziness, but any unit testing
tool would do (after cosmetic changes to the code).
The "test case" contains two pretty obvious tests, just read the
function names, their bodies should be pretty obvious. On thing that
might be a little non-obvious is the strval(): that was the only way I
found to get the string out of the very uncommunicative
SimpleXMLElement.

That's one of the reasons I didn't go the regexp route.
Don't treat XML as text, it's not.
