PHP解析文本和描述SimpleXML

Question

I'm trying to parse the text and description field from the code provided:

<?
$news = simplexml_load_file('http://en.wikipedia.org/w/api.php?action=opensearch&search=mandarin%20comics&format=xml&limit=1');

foreach($news->section->item as $item) {
    echo "<strong>" . $item->text . "</strong><br />";
    echo strip_tags($item->description) ."<br /><br />";
}
?>

It's giving me this error:

Invalid argument supplied for foreach() on line 4

How can I fix this?

Var_dump:

object(SimpleXMLElement)#1 (3) { ["@attributes"]=> array(1) { ["version"]=> string(3) "2.0" } ["Query"]=> string(15) "mandarin comics" ["Section"]=> object(SimpleXMLElement)#3 (1) { ["Item"]=> object(SimpleXMLElement)#2 (3) { ["Text"]=> string(17) "Mandarin (comics)" ["Description"]=> string(109) "The Mandarin is a fictional character, a supervillain who appears in comic books published by Marvel Comics. " ["Url"]=> string(46) "http://en.wikipedia.org/wiki/Mandarin_(comics)" } } }

Here is a link to the xml page: http://en.wikipedia.org/w/api.php?action=opensearch&search=mandarin%20comics&format=xml&limit=1

XML is case sensitive, so:

foreach($news->Section->Item as $item) {
    echo "<strong>" . $item->Text . "</strong><br />";
    echo strip_tags($item->Description) ."<br /><br />";
}
