Can someone help me out on this. I have a problem with the return results from an google-api call

Ben html olarak onları geri yankı istiyorum, ama firefox bir besleme sayfasını görüntüleyen tutar.

In IE, I get an error saying that an xml document can only contain one toplevel element wich must be the atom "feed" element, so I don't get that.

Ben bu konuda geliştirmek için ne yapabilirim?

$response= curl_exec($ch);

curl_close($ch);

// Parse the response
$response= simplexml_load_string($response);

foreach($response->entry as $position)
{
    echo "position: " . $position->title . "<br />";

/ / Sonraki stockvalue olurdu, ama ben henüz nasıl bilmiyorum

}

edit

$headers = array(
    "Authorization: GoogleLogin auth=" . $auth,
    "GData-Version: 2",
);

 $ch=curl_init(); 
curl_setopt($ch, CURLOPT_URL, "http://finance.google.com/finance/feeds/default/portfolios/1/positions");
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

edit I saw my mistake I did not use

curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);

teşekkürler, Richard
