Delphi soap response save to xml? [closed]

Question

How can I save soap response to xml? I tried with tstringlist, filestream, created the xml file but, but I got

could not convert varinat of type (null) into (type (olestr)

I tried this simple code.The response is not empty.The file size 40MB. Delphi XE3.

procedure TForm1.HTTPRIO1AfterExecute(const MethodName: string;
SOAPResponse: TStream);
var xml : TStringlist;
begin
 xml := TStringlist.create;
  try
    soapresponse.Position:=0;
    xml.LoadFromStream(SOAPResponse);
    xml.SaveToFile('...file.xml');
 finally
  xml.Free;
 end;
end;

this is the problem(empty lines)? or not ?

Did you try dumping your stream directly to a file, to see what’s in there?

procedure TForm1.HTTPRIO1AfterExecute(const MethodName: string; SOAPResponse: TStream);
var 
  FS: TFileStream;
begin
  FS := TFileStream.Create('C:\Downloaded.xml', fmCreate);
  try
    FS.CopyFrom(SoapResponse, 0);
  finally
    FS.Free;
  end;
end;
