我知道有很多问题已经被提出和回答，但没有一个与我的问题有关。
我将 XML 发布到服务器并收到回复。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，但是当使用 NSXML 将 XML 解析为文本时，我只能返回女性和 ID 2，而我没有返回男性？
我已经研究并尝试解决此问题，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"

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"];

parser.rowElementName = @"return";
parser.elementNames = [NSArray arrayWithObjects:@"response", @"responseCode", @"responseDesc", @"gendersList", nil];

if ([parser.rowElementName isEqualToString:@"responseCode"] && _flag)

NSString *userRes = [loginResponse objectForKey:@"id"];
NSString *test = [loginAuth description];
NSLog(@"Returned Code loginResponse %@",loginResponse);
NSLog(@"Returned Code userResponse %@ %@",userResponse, userRes);
NSLog(@"Returned Code test %@",test);
NSMutableArray *array=[[NSMutableArray alloc]initWithCapacity:10];
for (NSDictionary *defineXMLData in loginAuth) {

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

// delegate:nil
// cancelButtonTitle:@"OK"
// otherButtonTitles:nil] show];
}
}
else
{
NSLog(@"theConnection is NULL");
}
NSLog(@"test");
}
我从我的 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>
只是解析：
{
gendersList = Female2;
responseCode = "-1";
responseDesc = Success;
}
