In this XML, I got 11 items in an array. How can I deserialize it and get the item one by one?

Answer 1

You could use an XML parser.
There is support for a couple of methods in Cocoa - but since you've asked such a general question, all I can do is provide a general answer.
There is an Introduction to Event Driven XML Programming on the Apple Developer site
