Hi all,

I have a xml source and now i would like to present in my tableview.

You're really asking about quite a lot. My advice to you is to slowly go through Apple's Core Data sample projects (example), the Cocoa Dev Central Core Data tutorial to get down how to integrate tables and data models. Then, if you're comfortable with C, take a look at Apple's XMLPerformance sample project, which makes use of libxml2.
