Parsing XML with SimpleXML returns nothing - php

Question

I'm currently trying to parse the MapQuest Traffic API, but when I try to display an incident, nothing appears, and if I do "if empty" in php, it returns empty.
Here's the code:
<?php
$mysongs = simplexml_load_file("http://www.mapquestapi.com/traffic/v1/incidents?key=Fmjtd%7Cluuan1u2nh%2C2a%3Do5-96rw5u&callback=handleIncidentsResponse&boundingBox=$_GET[a], $_GET[b], $_GET[c], $_GET[d]&filters=construction,incidents&inFormat=kvp&outFormat=xml");
echo $mysongs->Incidents[0]->Incident[0]->fullDesc;
?>
The parameters I'm passing: ?a=33.352532499999995&b=-118.2324383&c=34.352532499999995&d=-117.2324383.
Thanks in advance!

Here simplexml_load_file not loading all your xml data so, i created a xml file with name test.xml and then loaded data from test.xml. Now you can print data what you need.
<?php
$a = $_GET['a'];
$b = $_GET['b'];
$c = $_GET['c'];
$d = $_GET['d'];
$xml_feed_url = 'http://www.mapquestapi.com/traffic/v1/incidents?key=Fmjtd|luuan1u2nh%2C2a%3Do5-96rw5u&callback=handleIncidentsResponse&boundingBox='.$a.','.$b.','.$c.','.$d.'&filters=construction,incidents&inFormat=kvp&outFormat=xml';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $xml_feed_url);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$xml = curl_exec($ch);
curl_close($ch);
$xml2 = new SimpleXMLElement($xml);
$xml2->asXML("test.xml");
$xml2->asXML();
$mysongs = simplexml_load_file("test.xml");
print_r($mysongs);
?>
