Objective-C DOM XML parser for iPhone
If you want to use libxml2 with an Objective-C front without SAX events, take a look at this useful set of wrapper functions.
You issue an XPath query to your XML document object and get back Foundation class objects: NSArray, NSString, and NSDictionary, e.g.:
NSArray *queriedBuckets = PerformXMLXPathQuery(responseData, @"//*[local-name()='Buckets']/*[local-name()='Bucket']");These functions help merge the speed of libxml2 with the readability and usability of Objective-C code.
I suggest looking at the Google Data API for Objective-C (iPhone) at http://code.google.com/p/gdata-objectivec-client/
In particular, look at these files which define the GDataXMLNode class:
