[PHP] simplexml_load_file und xpath

[oneside]

Hallo,

ich versuche gerade eine Twitter XML-Datei per PHP einzulesen, scheitere aber an der Angabe für xpath.

Ich nutze folgende Funktion:

function get_rss_items($url) {


    // retrieve search results

    if($xml = simplexml_load_file($url, 'SimpleXMLElement', LIBXML_NOCDATA)) {

        $result["title"]   = $xml->xpath("/feed/entry/title");


        foreach($result as $key => $attribute) {

            $i=0;

            foreach($attribute as $element) {

                $ret[$i][$key] = (string)$element;

                $i++;

            }

        }   

        return $ret;   

    } else

        return false;   

} [/PHP]

Wenn ich die Funktion jetzt für folgenden URL ausführe:

Code:

[code] http://search.twitter.com/search.atom?q=from:ashtonfans&rpp=5[/code]

Funktioniert es nicht, ich bekomme einfach nichts zurück. Ich habe es schon mit unterschiedlichen xpath-Angaben versucht, bekomme es aber nicht hin.

Es liegt wohl an der Formatierung der XML Datei nehme ich an.

Wenn ich mir das Ergebnis von simplexml_load_file mal durch var_dump($xml) ansehe, bekomme ich dieses Ergebnis:

Hat jemand eine Idee?

Danke

1) var_dump($result)

dürfte etwa so aussehen:

Array

(

[0] => SimpleXMLElement Object

  (

  [0] => <titel>

  )

)

2) list( , $result["title"]) = $xml->xpath("/feed/entry/title");
