   &soapReq.AddMethod("GETDAYATTENDANCE", 1);
   &soapReq.AddParm("strID", "mengxz");
  
   
   &result = &soapReq.ValidateSOAPDoc();
   If &result = 0 Then
      
      Warning &soapReq.GenXmlString();
      &request = &soapReq.XmlDoc;
      &response = SyncRequestXmlDoc(&request, Message.GETDAYATTENDANCEREQUEST, Node.PSFT_HR);
      
      &soapRes = CreateSOAPDoc();
      &soapRes.XmlDoc = &response;
      &OK = &soapRes.ValidateSOAPDoc();
      
      
      If All(&OK) Then
         &strXml = &soapRes.GenXmlString();
         
         MessageBox(0, "", 0, 0, &strXml);
      Else
         MessageBox(0, "", 0, 0, "Error. No reply");
