我正在开发 Delphi 7(个人)。我曾经使用 JvSimpleXML 进行 XML 处理,但它似乎不能处理 WideStrings(或者是吗?!)。我的整个项目使用 TntWide... & SpTBXLib 作为接口,因此它确实可以很好地处理 Unicode,我现在需要将一些设置存储在文件中...所以我正在寻找解决方案或(免费)替换 JvSimpleXML ...任何想法?

在此先感谢

您可以使用最新版本的MSXML 6(Microsoft XML 核心服务)从 delphi 导入 dll。

这是生成的代码示例

编辑

位于 XMLDoc.pas 中的对象 TXMLDocument(对于 delphi 7)是 MSXML 4 或更低版本的包装器。

const
  { GUID's from MSXML2_TLB.pas }
  CLASS_DOMDocument26: TGUID = '{F5078F1B-C551-11D3-89B9-0000F81FE221}';
  CLASS_DOMDocument30: TGUID = '{F5078F32-C551-11D3-89B9-0000F81FE221}';
  CLASS_DOMDocument40: TGUID = '{88D969C0-F192-11D4-A65F-0040963251E5}';

function CreateDOMDocument: IXMLDOMDocument;
begin
  Result := TryObjectCreate([CLASS_DOMDocument40, CLASS_DOMDocument30,
    CLASS_DOMDocument26, msxml.CLASS_DOMDocument]) as IXMLDOMDocument;
  if not Assigned(Result) then
    raise DOMException.Create(SMSDOMNotInstalled);
end;

来自微软网站:

引入 MSXML4 是为了添加功能和提高性能,但已被 MSXML6 取代。使用 MSXML4 的客户应该考虑在计划限制允许的情况下尽快迁移到 MSXML6。

Delphi 附带的 TXMLDocument 可以很好地处理 WideStrings/Unicode。默认情况下,它使用这里提到的 MSXML 库。它是一个类似于 DOM 的 API。有关示例,请参见http://delphi.about.com/library/weekly/aa101904a.htm 。

结帐OmniXML。我已经开始使用它而不是 msxml。它还为您提供了非常漂亮的“ FluentXMLBuilder ”。

经济实惠但不是免费的,Storage Library @ http://www.deepsoftware.com/rsllib/将保存为 XML、INI、Regitry 等。

如果您需要检查 XSD 模式或使用 XSL 进行转换,您应该查看DIXml
