 NSInteger type=[[(GDataXMLNode *)[[urls objectAtIndex:i] attributeForName:@"type"] stringValue] intValue];
 NSInteger bit_stream=[[(GDataXMLNode *)[[urls objectAtIndex:i]attributeForName:@"bit_stream"] stringValue] intValue];

Google have provided quite a lot of sample code that shows how to use their API. Depending of which protocol you use, you should be able to get the samples from the API Directory.
