iphone - 标记内的MWFeedParser标记(媒体:缩略图)

Question

我正在使用MWFeedParser从此处读取Youtube原子供稿:here

xml代码:

 <media:thumbnail url='http://i.ytimg.com/vi/7_1PfqGVSg0/0.jpg' height='240' width='320' time='00:01:34.500'/>

我如何获取媒体的网址:缩略图？
我试图更改MWFeedParser.m
由此:

else if ([currentPath isEqualToString:@"/feed/entry/link"]) { [self processAtomLink:currentElementAttributes andAddToMWObject:item]; processed = YES; }

对此:

else if ([currentPath isEqualToString:@"/feed/entry/media:thumbnail"]) { [self processAtomLink:currentElementAttributes andAddToMWObject:item]; processed = YES; }

但它不起作用:(

在部分案例FeedTypeAtom中，添加以下代码:

else if ([currentPath isEqualToString:@"/feed/entry/media:group/media:thumbnail"]) {
    NSString *urlString = [currentElementAttributes objectForKey:@"url"];                   
    if ( urlString != nil && urlString.length > 0) 
        item.thumbnail = urlString;  
    processed = YES;
}

还将NSString * thumbnail属性添加到MWFeedItem对象
