SimpleXML PHP Cannot Create Object

I am attempting to do what I think should be rather simple. I want to take a XML string from a text box and convert it into a SimpleXML object to parse, once I have the data in the SimpleXML object I will load it into a database (this part I have no issues with) for later use.

The code seems simple enough and my XML appears to be OK but I keep getting can not create object.

Upload.php

<form action="parse.php" method="get">
<textarea name="XML" rows="20" cols="60">Delete this text and Paste XML string here... </textarea>
<br></br>
<input type="submit" value="Upload Data">
</form>

Parse.php

<?php $myXMLData = $_GET["XML"]; 

$xml=simplexml_load_string($myXMLData) or die("Error: Cannot create object");
print_r($xml);

?>

XML Text - As far as I can tell using W3Schools XML validation the format is OK.
