Parsing XML Attributes by name with PHP5

When trying to parse an XML document in PHP, nothing is returned.

The XML document im trying to use:

The code I have tried:


$player = simplexml_load_file('http://ift.tt/1vRwpvt');
foreach ($player->PlayerName as $playerInfo) {
     echo $playerInfo['firstName'];
}

I have also tried:


$player = simplexml_load_file('http://ift.tt/1vRwpvt');
echo "Name: " . $player->PlayerName[0]['firstName'];

What do I need to change for the attributes to show?
