我想解析具有相同名称但不同值的孩子的 rss。在这种情况下，我想解析来自子名称“类别”的值。

这是RSS格式：

我做了这样的事情：

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"];
 }

在这段代码中，我只从子名称类别中获得了第一个值。我如何解析这个孩子的所有价值并在一行中显示？任何想法？

非常感谢
