How to create a TXML Document using MSXML 6.0 in Delphi 7?

Question

MSXML 6.0 didn't exist when Delphi 7 was released. Is it possible to configure Delphi's TXML Document to use MSXML 6.0 instead of the older versions?

Answer 1

Add the below code to a unit name uMSXMLVersion or your name of choice and add it to your projects uses

{----------------------------------------------------------------------------    
  Set Delphi's XMLDocument to use MSXML v6.0

  Usage:  Include unit in project "uses"-list and Delphi will automatically use
          MSXML v6.0 for TXmlDocument.
-----------------------------------------------------------------------------}
unit uMSXMLVersion;

interface

implementation

uses ActiveX, MSXML, MSXMLDOM;

function CreateDOMDocumentEx: IXMLDOMDocument;
const
  CLASS_DOMDocument60: TGUID = '{88D96A05-F192-11D4-A65F-0040963251E5}';
begin
  Result := nil;
  if CoCreateInstance(CLASS_DOMDocument60, nil, CLSCTX_INPROC_SERVER or
    CLSCTX_LOCAL_SERVER, IXMLDOMDocument, Result) <> S_OK then
  Result := CreateDOMDocument; //call the default implementation
end;

initialization
  MSXMLDOMDocumentCreate := CreateDOMDocumentEx;

end.
