I am going to use NSXMLElementin my project, so I tried
NSXMLElement
#import <Foundation/NSXMLDocument.h>
but it gives an error: "There is no such file or directory." How can I enable this?
NSXMLDocument is a class only for OS X
http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Classes/NSXMLDocument_Class/Reference/Reference.html
You cannot use it in iOS.
