NSXMLParser未检测到childes节点

Question

我有Web服务返回XML，我使用NSXMLParser从XML获取值。 这是我的代码：

//---when the start of an element is found---
-(void) parser:(NSXMLParser *) parser didStartElement:(NSString *) elementName namespaceURI:(NSString *) namespaceURI qualifiedName:(NSString *) qName attributes:(NSDictionary *)attributeDict {


    NSLog(@"Start Element : %@",elementName);

}

-(void)parser:(NSXMLParser *) parser foundCharacters:(NSString *)string
{//NSLog(@" parser  foundCharacters");

 NSLog(@"Found Char : %@",string);

}

-(void)parser:(NSXMLParser *)parser
didEndElement:(NSString *)elementName
 namespaceURI:(NSString *)namespaceURI
qualifiedName:(NSString *)qName
{

        NSLog(@"End Element : %@",elementName);   

}

这是NSXMLParser的输出：
