Event-based XML parsers, like NSXMLParser, have great performance but they can be difficult to work with because the parser itself discards nearly all state while parsing the document. This leaves all that state handling up to you, the programmer. Even a moderately complicated XML document can easily result in a mess of conditionals, state flags, and temporary variables. So while it's probably not applicable to every XML scenario, I've found the following object-mapper pattern to be an effective way to map XML data to arbitrary objects such as Core Data models.

It's actually quite easy to replace your Core Data backing store even while your application is in use.
