Can I use XML-RPC class for this?

I doubt you will be able to use XML-RPC.

XML-RPC requires a server prepared to listen for the request. For example, a blog. You would develop an XML-RPC server capability within the controller that manages all of your posts. This way, when someone links to your blog (and they have trackbacks enabled), their blog will ping your XML-RPC server, and you can then do some stuff with that information (like list all of the blogs that have linked to this particular post).
