NSXMLParser is a SAX-parser that is part of the iOS SDK. There are plenty of tutorials available if your google-fu is strong.

In the NSXMLParser class, you read the attributes for an element in the following event supplied by the class:

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict;

The last argument attributes:(NSDictionary *)attributeDict gives you a dictionary of the attribute-value pairs if there are any.
