【问题描述】：

我正在使用 SOAP 网络服务。如果我在浏览器中检查网络服务，则响应为

[{"sno":null,"AirportCode":"YQM","Airport":"Moncton Airport","City":"Moncton","Country":"Canada"}]

但是当我签入 iOS 时，响应带有 xml tags.like this

[{"sno":null,"AirportCode":"YQM","Airport":"Moncton Airport","City":"Moncton","Country":"Canada"}]<?xml version="1.0" encoding="utf-8"?>

这是我的方法....

NSString *autenticationkey = [NSString stringWithFormat:@"authkey"];
    NSString *acode = @"YQM";
    //NSString *empty = @"";
    NSString *soapMessage = [NSString stringWithFormat:@"<?xml version=\"1.0\" encoding=\"utf-8\"?>"
                             "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">"
                             "<soap:Body>"
                             "<GetAirport xmlns=\"http://mapi.uk/\">"
                             "<Authkey>%@</Authkey>"
                             "<AirportCode>%@</AirportCode>"
                             "</GetAirport>"
                             "</soap:Body>"
                             "</soap:Envelope>"
                             ,autenticationkey,acode];


    NSData *soapData = [soapMessage dataUsingEncoding:NSUTF8StringEncoding];
    NSString *mainurlName = [NSString stringWithFormat:@"http://somuturlop/GetAirport"];
    NSURL *getcodeserviceUrl = [NSURL URLWithString:mainurlName];
    NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:getcodeserviceUrl];
    NSString *messageLength = [NSString stringWithFormat:@"%lu", (unsigned long)[soapMessage length]];

    [theRequest addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [theRequest addValue:@"http://mopi.uk" forHTTPHeaderField:@"SOAPAction"];
    [theRequest addValue:@"mpi.uk" forHTTPHeaderField:@"HOST"];
    [theRequest addValue:messageLength forHTTPHeaderField:@"Content-Length"];
    [theRequest setHTTPMethod:@"POST"];
    [theRequest setHTTPBody:soapData];




NSURLSession *session = [NSURLSession sharedSession];
    NSURLSessionDataTask *dataTask = [session dataTaskWithRequest:theRequest completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {


        if (error) {
            NSLog(@"data Task With Request error:%@", error);
            return;
        }
        if ([response isKindOfClass:[NSHTTPURLResponse class]]) {
            NSInteger statusCode = [(NSHTTPURLResponse *)response statusCode];

            if (statusCode != 200) {
                NSLog(@"data Task With Request HTTP status code :%ld", (long)statusCode);
                return;
            }
        }

        webData = [[NSMutableData alloc] init];
        [webData appendData:data];

        NSLog(@"Received bytes from the server :%lu", (unsigned long)[webData length]);
        resultString = [[NSMutableString alloc] initWithBytes:[webData bytes] length:[webData length] encoding:NSUTF8StringEncoding];

resultString 给出了这个结果。我想把这个 json 数据放入一个数组中。

我试过这个。但它没有工作

resultStringOne = [[NSMutableString alloc] initWithData:webData encoding:NSUTF8StringEncoding];
        NSError *jsonError;
        NSData *jsonData = [resultStringOne dataUsingEncoding:NSUTF8StringEncoding];
        NSArray *getArray = [NSJSONSerialization JSONObjectWithData:jsonData options:kNilOptions error:&jsonError]

【问题讨论】：

为什么你认为浏览器没有得到相同的标签？
Checkout link 用于目标中的 xml 解析。浏览器解析器和目标解析器处理的xml也不同，输出也不同，因为在目标c中，你可以额外获得xml标签，这样你就可以在ios端很好地处理它。
你查看浏览器响应的源代码了吗？ xml 标签可能在浏览器视图中不可见。
我想用这个响应数据（想把这个数据放到一个数组中）怎么做
你说结果不同，但没有提供证据。正如@thst 所写，浏览器中的源视图显示什么？

【解决方案1】：

找到了解决办法。我从字符串中删除了 xml 标签。现在它可以工作了..... 用这种方法去除xml标签。

- (NSString *)stringBystrippingxml:(NSString *)provideString
{
    NSRange range;
    while ((range = [provideString rangeOfString:@"<[^>]+>" options:NSRegularExpressionSearch]).location != NSNotFound)
        provideString = [provideString stringByReplacingCharactersInRange:range withString:@""];

    return provideString;
}

然后使用return provideString，然后.....

resultStringOne = [[NSMutableString alloc] initWithData:webData encoding:NSUTF8StringEncoding];
        NSString *one = [self stringBystrippingxml:resultStringOne];
        NSError *jsonError;
        NSData *jsonData = [one dataUsingEncoding:NSUTF8StringEncoding];
        NSArray *getArray = [NSJSONSerialization JSONObjectWithData:jsonData options:kNilOptions error:&jsonError];

这很好用....... thnx all 和thanx @m.kocikowski 用于标签删除方法。
