How to get dynamic ip in xml file?

I have 'links.xml' file it contains url's which is used to perform instant search and go for the particular page specified by the url.

'links.xml' source

<?xml version="1.0" encoding="utf-8"?>
<!-- Edited by XMLSpy -->
<pages>

<link>
<title>Advanced</title>
<url>http://ift.tt/1o1XYYy;

</link>

<link>
<title>States</title>
<url>http://ift.tt/WUHqMz;
</link>
</pages>

In above code: {192.168.44.128}=192.168.44.128 (I couldn't post the question without the braces.)

I want to send dynamic IP address in the url tag because IP address keeps changing and its not static IP. Along with this file I have used a php and a html file. So can dynamic address be provided in xml file only without making any changes to other files? If yes, then how? If not, then how to send dynamic IP address in the url tag.

This code is taken from: http://ift.tt/1o1XZeO
