XML with Cocoa Touch

Question

I am a new learner at the area of Objective-C. I would like to retrieve data from XML page on the iPhone. Is it possible? It would be more helpful to me if I get an appropriate suggestion or code.

Answer 1

The SDK comes with the NSXMLParser class. Some people prefer to use the libxml2 library as it can be faster and more memory efficient than NSXMLDocument but you may want to wrap it with an Objective C layer as it is a C API. See this example.

Answer 2

There was a good episode of cocoaFusion: the other day that covered the ins and outs of XML parsing. Head on over to cocoafusion.net and look for Episode 2: An intro to using web APIs and XML.

The show notes section for that episode has some sample code downloads and links to other sites that contain more information (including some of the links mentioned in the other answers here).

Cheers!
