XML-Ausgabe von Yahoo BOSS API mit PHP

Question

konnte ich bisher diesen Code erhalten:

<?php 
//Gather data and prepare query 
$thequery = urlencode($_GET['s']); 
$yhost = 'http://boss.yahooapis.com'; 
$apikey = 'xxxxxxxxxxxxxxx'; 
$url = $yhost.'/ysearch/news/v1/'.$thequery.'?appid='.$apikey.'&format=xml'; 
//Get the results 
$ch = curl_init($url); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_HEADER, 0); 
$data = curl_exec($ch); 
curl_close($ch); 
$results = new SimpleXmlElement($data, LIBXML_NOCDATA); 
//echo the results 
foreach ($results->resultset_news->result as $theresult) { 
echo '<a href="'.$theresult->clickurl.'">'.$theresult->title.'</a><br/>'; 
echo $theresult->abstract.'<br/>'; 
echo '<small><i>'.$theresult->dispurl.'</i></small><br/>'; 
echo '<br/><br/>'; 
} 

Wie genau tun i Ausgang eigentlichen XML statt HTML?
