奇怪的xml特殊字符，无法使用curl和SimpleXMLElement进行解析

I'm downloading an xml file using curl and then parsing it using simplexml_load_string() and putting it to db.

I got a problem a that the file cannot be parse, its inside <![CDATA[]]> and i notice the file has some sort of a special character that i really dont know:

special character

I'm getting the file like so:

$c = curl_init();
curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($c, CURLOPT_URL, $URL);
$contents = curl_exec($c);
curl_close($c);

and i'm parsing it like so:

$gpx = simplexml_load_string($myfile,'SimpleXMLElement', LIBXML_NOCDATA);

The error that I got is this:

simplexml_load_string(): Entity: line 7238: parser error : CData section not finished

How can i disregard those in to properly parse the xml file?

Thanks so much in advance.
