1. You can use NSXMLParser for this purpose, read through the delegate methods in https://developer.apple.com/library/ios/documentation/cocoa/reference/NSXMLParserDelegate_Protocol/Reference/Reference.html

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