I know there are third party libraries that simplify the process

assuming that you are going to store the attribute values into NSStrings.

NSString *ImageId;
NSString *Description;
NSString *Date;

you can use simple if statements.
if([Elementname isEqualToString:@"Result"]){
  ImageId = [attributeDict objectForKey:@"ImageId"];
  Description = [attributeDict objectForKey:@"Description"];
  Date = [attributeDict objectForKey:@"Date"];
}

So as you can see first you have to decide which element you are interested in which your case would be the "Result" element. Then you are telling the compiler that if the elementname is "Result" you want its attribute values stores under ImageId, Description & Date to be saved into NSStrings.
