XML Stack Overflow: Using xslt and cURL

This is my first attempt to perform a transform on an xml returned from cURL in the form of a string. I have a php that I think is written properly as I can at least echo back the string contained in $xml_data . However, whenever I attempt to view the php through a browser I get a blank page (and source). What am I doing wrong? Any pointers would be helpful and appreciated..

php


<?php
$ch = curl_init("http://ift.tt/1H5u18S");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$xml_data=curl_exec($ch);
curl_close($ch);

$xmlDoc = new DOMDocument();
$xml->$xml_data;

$xslDoc = new DOMDocument();
$xslDoc->load("new_releases.xsl");

$proc = new XSLTProcessor();
$proc->importStylesheet($xslDoc);

$xmlDoc->loadXML($xml_data);

echo $proc->transformToXML($xmlDoc);

$proc->setParameter('', 'albumid', $_POST["id"]);

?>

The XSL (note this is not complete, at this point I'm just attempting to get some of the data from xml on the screen and style it)


<xsl:stylesheet version="1.0" xmlns:xsl="http://ift.tt/tCZ8VR" xmlns="http://ift.tt/lH0Osb">

   <xsl:output method="html" />

    <xsl:template match="/">
    <html><body>
     <div style="position: relative; font-weight: bold; font-size: 24pt;">
        New music for the week of <xsl:value-of select="release_week_start"/></div>
      <xsl:for-each select="/album">
              <a xmlns="http://ift.tt/lH0Osb"
                href="{../@id}.xhtml">
                <xsl:value-of select="album/artist"/>
              </a>
      </xsl:for-each>        
 </body></html>



</xsl:stylesheet>

If I include echo $xml_data in my php I get the following xml string


<?xml version="1.0"?>
<new_release>
 <release_week_start date="January 26, 2014">
