Is there anyway to use WhatsApp with any of the XMPP clients? If yes, how it's done<p>The Wikipedia article says, it supports XMPP.

It's protocol is a customized version of XMPP, as per the wiki article. I doubt if any third party XMPP client will work with it.
Whatsapp doesn't have an open API, though some guys had managed to reverse engineer it last year. They have since updated their API apparently.
Unless whatsapp explicitly opens with API, I think we are stuck with their official apps on the phones.
As far as I know there currently is no way to accomplish this, but I am working on a solution for it.
Unfortunately the project just started and will take its time
