具有多个名称空间的Xml路径(Xml path that have multiple namespaces)

 我无法弄清楚需要使用哪些命名空间来跟随Xml（示例）： 
 
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
      <s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
        <ResponseCharge xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
          <ResponseInfo xmlns="http://www.example.net">
            <ResponseDetail>
              <ResponseCode>00</ResponseCode>
              <RequestIdentifier>1029034</RequestIdentifier>
              <RetrievalReferenceNumber>634716660366</RetrievalReferenceNumber>
              <ProcessingTime>00:03:314</ProcessingTime>
            </ResponseDetail>
            <ResponseTransactionDetail>
              <AVSResponseCode />
              <CVVResponseCode />
              <AuthorizationSourceCode />
              <AuthorizationNumber>004454</AuthorizationNumber>
            </ResponseTransactionDetail>
            <EMVResponseData />
          </ResponseInfo>
        </ResponseCharge>
      </s:Body>
    </s:Envelope>
 
 我的代码看起来像这个atm： 
 
    XmlDocument doc = new XmlDocument();
            doc.Load(responseXmlFile);
            var nsmgr = new XmlNamespaceManager(doc.NameTable);
            nsmgr.AddNamespace("s", "http://schemas.xmlsoap.org/soap/envelope/");
            //nsmgr.AddNamespace("xsi", "http://www.w3.org/2001/XMLSchema-instance");
            //nsmgr.AddNamespace("xsd", "http://www.w3.org/2001/XMLSchema");
            //nsmgr.AddNamespace("", "http://www.example.net");
            // getting NULL here
            XmlNode node = doc.SelectSingleNode("/s:Envelope/s:Body/ResponseCharge/ResponseInfo/ResponseTransactionDetail/AuthorizationNumber", nsmgr); 
 
 我正在关注这篇文章： 需要命名空间管理器或XsltContext 

I can't figure out what namespaces need to be used for following Xml (sample): 
 
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
      <s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
        <ResponseCharge xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
          <ResponseInfo xmlns="http://www.example.net">
            <ResponseDetail>
              <ResponseCode>00</ResponseCode>
              <RequestIdentifier>1029034</RequestIdentifier>
              <RetrievalReferenceNumber>634716660366</RetrievalReferenceNumber>
              <ProcessingTime>00:03:314</ProcessingTime>
            </ResponseDetail>
            <ResponseTransactionDetail>
              <AVSResponseCode />
              <CVVResponseCode />
              <AuthorizationSourceCode />
              <AuthorizationNumber>004454</AuthorizationNumber>
            </ResponseTransactionDetail>
            <EMVResponseData />
          </ResponseInfo>
        </ResponseCharge>
      </s:Body>
    </s:Envelope>
 
My code looks like this atm: 
 
    XmlDocument doc = new XmlDocument();
            doc.Load(responseXmlFile);
            var nsmgr = new XmlNamespaceManager(doc.NameTable);
            nsmgr.AddNamespace("s", "http://schemas.xmlsoap.org/soap/envelope/");
            //nsmgr.AddNamespace("xsi", "http://www.w3.org/2001/XMLSchema-instance");
            //nsmgr.AddNamespace("xsd", "http://www.w3.org/2001/XMLSchema");
            //nsmgr.AddNamespace("", "http://www.example.net");
            // getting NULL here
            XmlNode node = doc.SelectSingleNode("/s:Envelope/s:Body/ResponseCharge/ResponseInfo/ResponseTransactionDetail/AuthorizationNumber", nsmgr);
