Simple Zillow API call gives white screen

Question

I can't seem to get out of the gate. I have the following which gives nothing but white screen...

    <?php 
 $url = "http://www.zillow.com/webservice/GetDemographics.htm?zws-id=<my api      key>&state=CO&city=Denver&neighborhood=Stapleton";
 $data = simplexml_load_string(file_get_contents($url));
 print_r($data); 
?>

Not sure what I'm doing wrong.

thanx for your help!!

It works for me, maybe you don't have libxml installed with PHP? The blank screen could be the result of a fatal error.

Try changing your script to:

<?php 
error_reporting(E_ALL); // log all errors
ini_set('display_errors', 'on'); // display errors in output, rather than to error_log

$url = "http://www.zillow.com/webservice/GetDemographics.htm?zws-id=<my api      key>&state=CO&city=Denver&neighborhood=Stapleton";
$data = simplexml_load_string(file_get_contents($url));
print_r($data); 

The first two lines will likely result in some sort of error message being displayed which would be a blank page if display_errors is off.
