我是电话编程的新手。从 Web 服务调用中，我得到了响应，我必须从中获取数据。我已经尽我所能但无法做到这一点..我需要（这两个问题，即你童年最好的名字是什么？以及你的出生地是什么？）标签帮助中的值... .. 下面是我必须解析的 xml 响应....

NSMutableString *xmlString;

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)nameSpaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
    xmlString = [[NSMutableString alloc] init];    
}

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
    [xmlString appendString:string];
}

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{    
    if ([elementName isEqualToString:@"ns2:value"])
    {
        if (![xmlString isEqual:@""])
        {
            NSLog(@"%@",xmlString);
            [SomeArray addObject:xmlString];
        }
    }

    //Release string
    [xmlString release];
    xmlString = nil;
}

这NSMutableString是一个变量，它跟踪foundCharacters方法中的当前元素，并使用 elementName 附加字符串和didEndElement方法，我们可以识别该标记的值。

更新

- (void)parserDidEndDocument:(NSXMLParser *)parser
{
    //update your UI here after parsing is finished
}
