This is an extract of AQXMLParser from AQToolkit.
5 easy steps:
- Add AQXMLParser.m and AQXMLParser.h to your project.

- Replace the word NSXMLParser with AQXMLParser, and add #include “AQXMLParser.h” in affected sources
It revolves around a new event-based XML parser, designed to function in nearly the same manner as NSXMLParser, with the same delegation routines. The main difference is that AQXMLParser is a streaming parser and it provides data in discrete blocks to the libxml2 parser library. This means significant memory savings for large XML documents – this can be especially important on iPhone.
It also allows NSInputStream/NSURLRequest as its data source – in addition to NSData and NSURL.
It is initialized, setup, and used in the same way as a standard NSXMLParser. Note that, for compile-time type checking, the delegate routines for AQXMLParser are declared again here, with AQXMLParser replacing NSXMLParser. These routines are now also declared inside a protocol using the @optional keyword, to match the new delegation API constructs used in the iPhone SDK. Also the use AQXMLParserDelegate protocol is optional.
AQXMLParser is fully gc-compliant, or can be used in a managed-memory environment.
