Hi.
I'm getting a parser error on my XML feed from YouTube's friend activity feed.
The error I am recieving is:

Warning: SimpleXMLElement::__construct() [function.SimpleXMLElement---construct]: Entity: line 1: parser error : Premature end of data in tag feed line 1 in /media/morpheus/yasn/includes/youtube.php on line 86

Warning: SimpleXMLElement::__construct() [function.SimpleXMLElement---construct]: ^ in /media/morpheus/yasn/includes/youtube.php on line 86

Fatal error: Uncaught exception 'Exception' with message 'String could not be parsed as XML' in /media/morpheus/yasn/includes/youtube.php:86 Stack trace: #0 /media/morpheus/yasn/includes/youtube.php(86): SimpleXMLElement->__construct('<feed xmlns='ht...') #1 /media/morpheus/yasn/stream_test.php(70): YouTube->get_friends_activity() #2 {main} thrown in /media/morpheus/yasn/includes/youtube.php on line 86

The content of the XML feed is: (spaced out so easier to read)

Could someone help me to see why this is not valid and how to solve the problem?
Thanks.

I have the same problem, any ideas?

I had the same error and fixed it by loading DOM first, then converting to SimpleXML. Instead of just loading the XML string directly to SimpleXML. Have no idea why SimpleXML errorer on loading the google custom search results xml string.

$this->xmlDoc = file_get_contents($this->url, 0, stream_context_create(array('http' => array('timeout' => 1))) );

if(!$this->xmlDoc) $this->error = "Could not get $url";
else
{
$dom = new DOMDocument;
$dom->loadXML($this->xmlDoc);
if (!$dom)
{
echo 'Error while parsing the document';
exit;
}
$this->xmlObj = simplexml_import_dom($dom);
/*
try {
$this->xmlObj = new SimpleXMLElement($this->xmlDoc);
}
catch (Exception $e)
{
$this->error = "SimpleXML did not work";
echo $this->error; exit;
}
*/
}


Error message before the fix was:
