Python Framework for Symbian Series 60 phones

In that piece of source I demonstrate how I get info on a server via XML file. You just need to write the XML parser to extract an condition the data as you need.

For parsing XML documents, I'm using cElementTree ported on PyS60 by Simo Salminen (available 2nd & 3rd edition).

You need to write a server script that generate your XML document if it is not static. PHP, JSP, Python... Up to you :)
