Satish,

You can always add and remove XML elements on the fly and then use XML 
parsing routines to figure out incoming packets. However, it sounds like 
you're just looking for a very simple way to to programatically pass 
info back and forth between two XMPP nodes? If so, I'd recommend 
checking out our Open Source client library Smack -- 
http://www.jivesoftware.com/xmpp/smack

The feature that may help you most is the ability to attach an arbitrary 
map of data (including Java objects) to each packet. As an example:

Setting Properties:

Message message = chat.createMessage();
// Add a Color object as a property.
message.setProperty("favoriteColor", new Color(0, 0, 255));
// Add an int as a property.
message.setProperty("favoriteNumber", 4);
chat.sendMessage(message);

Getting those same properties would use the following code:

Message message = chat.nextMessage();
// Get a Color object property.
Color favoriteColor = (Color)message.getProperty("favoriteColor");
// Get an int property. Note that properties are always returned as
// Objects, so we must cast the value to an Integer, then convert
// it to an int.
int favoriteNumber = 
((Integer)message.getProperty("favoriteNumber")).intValue();


This is a different solution than what you were asking for, but it could 
be much simpler if I understand the problem you're trying to solve.

Regards,
Matt
