I did something like this:

NSArray *channels = [rootElement elementsForName:@"channel"];
for (GDataXMLElement *channel in channels) {            

    NSString *blogTitle = [channel valueForChild:@"title"];                    
    NSLog(@"blogTitle %@",blogTitle);
    NSArray *items = [channel elementsForName:@"item"];
    for (GDataXMLElement *item in items) {

        NSString *articleTitle = [item valueForChild:@"title"];
        NSString *articleUrl = [item valueForChild:@"link"];            
        NSString *articleDateString = [item valueForChild:@"pubDate"];
        NSString *articleDescription = [item valueForChild:@"description"];
        NSDate *articleDate = [NSDate dateFromInternetDateTimeString:articleDateString formatHint:DateFormatHintRFC822];
        NSDate *timeStamp = [NSDate date];
        NSString *category = [item valueForChild:@"category"];
 }

Fron this code, I got only first value from child name category. How do i parse all value from this child and show in one line? Any idea?

Many Thanks
