If you look at the NSXMLParser header file you'll see that the error code 3 in 
the NSXMLParserErrorDomain means NSXMLParserDocumentStartError

So clearly there was a problem with the start of the document (which would 
explain why delegate methods didn't get called).

If you want people to be able to help more than that, you probably need to 
supply some minimal (but complete) source code and a the xml data you used:  
that way people can try compiling it and running it.
In the absence of that sort of information, my guess would be that you are 
starting with something that's not a valid xml document, and the parsing is 
failing when the parser tries to find the document start.
