NSXML XML 解析问题 iOS.

Question

我知道有很多问题已经被提出和回答，没有一个与我的问题有关。

我正在将 XML 发布到服务器，并得到回复。我的问题是从响应中获取指定的密钥。

我正在尝试列出所有性别，例如男性、女性及其 ID，但是在使用 NSXML 将 XML 解析为文本时，我只返回女性和 ID 2，而没有返回男性？

我已经研究并试图解决这个问题，但无济于事。

这是我的代码：

- (void)getGender {
    NSString *soapMessage = [NSString stringWithFormat:
                             @"<?xml version="1.0" encoding="utf-8"?>n"
                             "<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/" xmlns:app="http://app.ws.api.bells.wigroup.com/">"

                             ];
    NSLog(@"Message%@",soapMessage);
    NSURL *url = [NSURL URLWithString:@"http://qa.wigroup.co:8080/bells/AppWS"];
    NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
    NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]];
    [theRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    //[theRequest addValue: @"http://" forHTTPHeaderField:@"SOAPAction"];
    [theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];

        // create and init NSXMLParser object
        XmlArrayParser *parser = [[XmlArrayParser alloc] initWithData:urlData];
        parser.rowElementName = @"return";

            for (NSDictionary *defineXMLData in loginAuth) {
                NSNumber * responseCode = [defineXMLData objectForKey:@"responseCode"];
                NSArray * responseDEsc = [defineXMLData objectForKey:@"responseDesc"];
                NSArray * genderList = [defineXMLData objectForKey:@"gendersList"];
               // NSArray * gender = [defineJsonData objectForKey:@"gender"];
                NSLog(@"Genders%@", genderList);
                [array addObject: responseCode];
                [array addObject: responseDEsc];
                [array addObject: genderList];
                //[array addObject: gender];

            }
            label.numberOfLines = 2000; // for example
            label.lineBreakMode = NSLineBreakByClipping;
            NSString *output=[array componentsJoinedByString:@","];

            //                              otherButtonTitles:nil] show];
        }
        else
        {
            NSLog(@"Error parsing document!");
            //            [[[UIAlertView alloc] initWithTitle:nil
            //                                        message:@"Error parsing document!"
            //                                       delegate:nil
            //                              cancelButtonTitle:@"OK"
            //                              otherButtonTitles:nil] show];
        }
    }
    else
    {
        NSLog(@"theConnection is NULL");
    }
    NSLog(@"test");
}

以及我从nslog中返回的XML：

<?xml version="1.0" encoding="UTF-8"?>
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
   <S:Body>
      <ns2:getAllGendersResponse xmlns:ns2="http://app.ws.api.bells.wigroup.com/">
         <return>
            <responseCode>-1</responseCode>
            <responseDesc>Success</responseDesc>
            <response>
               <responseCode>-1</responseCode>
               <responseDesc>Success</responseDesc>
               <gendersList>
                  <gender>Male</gender>
                  <id>1</id>
               </gendersList>
               <gendersList>
                  <gender>Female</gender>
                  <id>2</id>
               </gendersList>
            </response>

只是解析：

{
gendersList = Female2;
responseCode = "-1";
responseDesc = Success;
}

Answer 1

您没有正确指出问题。您的代码解析整个文档，但您只保留最后一项（最后一个性别列表、最后一个响应代码、最后一个响应Desc）。初始化一个数组，并在 for 循环中解析时将每个字典添加到该数组中。
