[xsl] php xml xsl transformation returning empty string

[nalopaleaahu@xxxxxxx]

Hmm I thought the closing xml was well formed, I was wrong. Thanks

Now I dont get parsing errors now but the transformation is not 
returning anything new, just the comment segment as it was before 
sending it to rdfpic2html. I am trying to modify 
http://www.ozhiker.com/electronics/pjmt/ PJMT's JPEG.php to transform 
http://jigsaw.w3.org/rdfpic/ rdfpic xml in the comment segment of jpegs 
and return it to Example.php

function Interpret_Comment_to_HTML( $jpeg_header_data )
{
       // Create a string to receive the output
       $output = "";

       // read the comment segment
       $comment = get_jpeg_Comment( $jpeg_header_data );

       // Check if the comment segment was valid
       if ( $comment !== FALSE )
       {
        // Check if the string contains an indicator that there may be 
rdfpic metadata
       if (stristr($comment, 'PhotoRDF') !== FALSE)
       {
       $rdfpicdata = stristr($comment, '<?xml');
        rdfpic2html( $rdfpicdata );
           $output .= $rdfpichtml;
       }
               // Comment exists - add it to the output
                $output .= "<h2 
class=\"JPEG_Comment_Main_Heading\">JPEG Comment</h2>\n";
                $output .= "<p 
class=\"JPEG_Comment_Text\">$comment</p>\n";
       }

       // Return the result
       return $output;
}


function rdfpic2html( $rdfpicdata )
{
  $arguments = array('/_rdf' => $rdfpicdata);
  $xsltproc = xslt_create();
  xslt_set_encoding($xsltproc, 'ISO-8859-1');
   $rdfpichtml = xslt_process($xsltproc, 'arg:/_rdf', 'rdfpic.xsl', 
NULL, $arguments);
  if (empty($rdfpichtml)) {
      die('XSLT processing error: '. xslt_error($xsltproc));
  }
  xslt_free($xsltproc);
  return $rdfpichtml;
}
