NSXML XML解析问题iOS

Question

我知道有很多问题已经被问到和回答了，但没有一个是关于我的问题的。

我正在将XML发布到服务器上，并且得到了一个响应。我的问题是从响应中取回一个指定的键。

我正在尝试列出所有的性别，例如男性，女性和他们的ID，然而，当使用NSXML将XML解析为文本时，我只得到女性和ID 2，而我没有得到男性？

我已经研究并尝试解决这个问题，但无济于事。

下面是我的代码：

- (void)getGender {

    NSString *soapMessage = [NSString stringWithFormat:
                             @"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"

    NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];

    }
    else

        NSLog(@"theConnection is NULL");
    }

    NSLog(@"test");

}

和我从nslog中得到的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>

只是在解析：

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

Answer 1

您没有正确指出问题所在。您的代码将解析整个文档，但只保留最后一项(last genderList、last responseCode、last responseDesc)。初始化一个数组，并在解析时在for循环中将每个字典添加到数组中。
