有任何動態XML解析

Question

如何在XML屬性變化解析......」

例如

<Root> 
<child name="", age="",phone="",address=""/> 
</Root> 

這是我從網絡服務器通過第一iphone要求....我解析上面的XML ...

之後，當我請求相同的網址..這是現在更新它我的XML子標籤更改。

<Root> 
<child name="",age="",phone="",address="",office="",mobile="",location=""/> 
</Root> 

額外的三個屬性加..

做什麼用這種方法..任何例子請發...在此先感謝

-(void)startParsingForSendFriendRequest:(NSString *)userID Friend:(NSString*)friendID 
{ 

    NSString *urlString =[NSStringstringWithFormat:@"http:///user_id=%@&friend_id=%@",userID,friendID]; 

    ////NSLog(@"urlString : %@",urlString); 
    NSURL *xmlURL = [NSURL URLWithString:urlString]; 

    NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] initWithURL:xmlURL cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:30.0]autorelease]; 

    NSURLResponse *returnedResponse = nil; 
    NSError *returnedError = nil; 
    NSData *itemData = [NSURLConnection sendSynchronousRequest:request returningResponse:&returnedResponse error:&returnedError]; 
    //NSString *itemString = [[[NSString alloc] initWithBytes:[itemData bytes] length:[itemData length] encoding:NSUTF8StringEncoding]autorelease]; 

    //NSLog(@"itemString : %@",itemString); 


    NSXMLParser *xmlParser = [[NSXMLParser alloc] initWithData:itemData];  
    [xmlParser setDelegate:self]; 

    [xmlParser parse]; 

}
