如何解析从iphone XML页面的第二子节点

Question

我是新iphone development.I要解析你管的XML页面，并在RSS订阅其内容检索和显示。

我的XML页是

<entry>
<id>xxxxx</id>
<title>xxx xxxx xxxx</title>
<content>xxxxxxxxxxx</content>
<media:group>
 <media:thumbnail url="http://tiger.jpg"/>
</media:group>
</entry>

要检索内容，我使用的XML解析。

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{            

currentElement = [elementName copy];
if ([elementName isEqualToString:@"entry"]) {

    entry = [[NSMutableDictionary alloc] init];
    currentTitle = [[NSMutableString alloc] init];
    currentcontent = [[NSMutableString alloc] init];
    }

}


- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName{     
if ([elementName isEqualToString:@"entry"]) {
    [entry setObject:currentTitle forKey:@"title"];
    [entry setObject:currentDate forKey:@"content"];
    [stories addObject:[entry copy]];
    }}

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string{

if ([currentElement isEqualToString:@"title"]) {
    [currentTitle appendString:string];
} else if ([currentElement isEqualToString:@"content"]) {
    [currentLink appendString:string];
 }
 }

我能够找回ID，标题和内容的价值，并在table-view.How我可以检索虎图像的URL显示它并表view.Please显示它帮助我out.Thanks。
