Parsing xml to php

I am parsing xml to php with the below code

$xml = simplexml_load_file($file_name);

Here $file_name is http://ift.tt/1nHiVrL

This vast generates its content based on the country location.

But i have hosted this code using aws in us-west area.

In us-west this xml file output will be like

<VAST version="2.0">
<Ad id="Ventuno"/>
</VAST>

But for india the output will be like this.

My code is not working because i have hosted it in us-west.If i parse the xml file it gives output for US only.But i want output for india.So,How to do it.
