SimpleXML Problems

[dennismonsewicz]

I am trying to retrieve an attribute from a node and I keep getting the error:

Warning: main() [function.main]: Node no longer exists in /Users/dmonsewicz/Projects/noosemonsewicz/api_stuff/index.php on line 70

 

PHP Code

$xml = new SimpleXMLElement($result);
$arr = $xml->tickets->attributes();
echo $arr['count'];

 

XML

<tickets count="0" type="array"></tickets>

 

Any ideas on what I may be doing wrong?

I figured out what I was doing wrong.

 

$xml = new SimpleXMLElement($result);
$ticket_count = (string) $xml['count'];

 

The first node in the XML was what I was trying to work with and I was going levels in.
