XML Nightmare from C# to ASP

[sgentry]

Cannot read the XML response from my C# app with regular ASP unless I save it to a file first. The workaround is not acceptable. I should be able to load, read, and extract the data from the XML response.

Error received = “424 Object required” whenever I try performing “selectSingleNode" against the XML Dom Document in my ASP.

I've heard mentioned that the C# HTTP header is included in the XML response, and I’ve sense tried changing it but with no improvement.

I’ve spent what seems like months trying to find a solution. I’ve tried every type of Google search imaginable. Microsoft won’t help me. Can you see anything wrong, or do you know an XML guru who can? The code is so simple.

(C#)
try {
    Response.ClearContent();
    Response.ContentType = "text/xml";
    XmlTextWriter xtWriter = new XmlTextWriter(Response.Output);
    xtWriter.WriteStartDocument();
    xtWriter.WriteStartElement("DocMergeResponse");
    xtWriter.WriteStartElement("Document");
    xtWriter.WriteAttributeString("dt:dt", "bin.base64");
    xtWriter.WriteAttributeString("LoanNumber", gsLoanNumber); //Global string
    xtWriter.WriteAttributeString("xmlns:dt", "urn:schemas-microsoft-com:datatypes");
    xtWriter.WriteBase64(gBinaryData, 0, gBinaryData.Length); //Global byte array
    xtWriter.WriteEndElement();
    xtWriter.WriteEndElement();
    xtWriter.WriteEndDocument();
    xtWriter.Close();            
}
catch(Exception xmlErr) {
    ProcessProgError("Failed to create XML response" + CRLF + xmlErr.ToString());
    return;
}
(/C#)
 
(ASP)
'// POST the XML document on the my C# app.
Set objSXH = server.createobject("msxml2.serverxmlhttp")
objSXH.open "POST", serverString & "/DocMerge/Default.aspx", False
objSXH.SetRequestHeader "Content-Type", "text/xml"
objSXH.send objXMLRequest.xml   '// XML post 
 
'XML IS NOW POSTED - LOOK FOR RESPONSE
strResponse = ""
strResponse = objSXH.ResponseText    '// Get the response.
objXMLDoc.load (strResponse)            ‘//LOAD XML from .NET app.
 
‘//ERROR TRAPPED ON NEXT STATEMENT
Response.Write objXMLDoc.selectSingleNode("/DocMergeResponse/Document/@LoanNumber").nodeTypedValue
If Err <> 0 then
  Response.Write "ERROR: " & sProgramName & " - TEST failed - " & Err.Number & " " & Err.Description
  Response.End
End If
(/ASP)

Thanks again for your help.

I believe that you have an ASP problem using your selectSingleNode. What happens if you try:

Response.Write objXMLDoc.selectSingleNode("LoanNumber").nodeTypedValue
