xpath with curl gives empty result?

Question

This code gives me an empty result. I expect it to print out the titles from the XML-file. I need to use Curl to get the file.

<?php    
function get_url($url)
{
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_URL, $url);
    $data = curl_exec($ch);
    curl_close($ch);

    return $data;
}

$xml_content = get_url("http://www.e24.se/?service=rss&amp;type=latest");

$dom = new DOMDocument();
@$dom->loadXML($xml_content);
$xpath = new DomXPath($dom);
$results = $xpath->query('//channel//title/text()');


foreach ($results as $result) 
{
    echo $result->title . "<br />";
}
?>

Answer 1

I found it already. The loop is wrong. It should be...

foreach ($results as $result) 
{
    echo $result->nodeValue . "<br />";
}
