Question

Delphi 7发布时，MSXML 6.0不存在。是否可以将Delphi的TXML文档配置为使用MSXML 6.0而不是旧版本？

Answer 1

将以下代码添加到单位名称uMSXMLVersion或您选择的名称，并将其添加到您的项目使用

{----------------------------------------------------------------------------    
  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.

Answer 2

msxmldom.pas单元公开了一个公共MSXMLDOMDocumentCreate挂钩，您可以为其分配自定义处理程序，例如：

uses
  ..., msxmldom;

const
  CLASS_DOMDocument60: TGUID = '{88D96A05-F192-11D4-A65F-0040963251E5}';

function CreateMSXML6Document: IXMLDOMDocument;
var
  Disp: IDispatch;
begin
  OleCheck(CoCreateInstance(CLASS_DOMDocument60, nil, CLSCTX_INPROC_SERVER or CLSCTX_LOCAL_SERVER, IDispatch, Disp));
  Result := Disp as IXMLDOMDocument;
  if not Assigned(Result) then
    raise DOMException.Create('MSXML 6.0 Not Installed');
end;

initialization
  msxmldom.MSXMLDOMDocumentCreate := CreateMSXML6Document;

如何在Delphi 7中使用MSXML 6.0创建TXML文档？
