display parsed xml within wordpress page

I have the following scriot which works great on a .php page.  However, I need it to work within a wordpress page but nothing displays in the page .  I do have the plugin PHP Execution installed and can run a siimple php script in the (html tab) page and I can see the results in my browser.  For some reason though, the following script display nothing.

Any ideas?

I do have simple pie plugin installed but have no idea how and if it can parse out xml and display it in a wp page.

<?php
error_reporting(E_ALL);

$xml = <<<XML
<?xml version="1.0" encoding="UTF-8" ?>
