Delphi 7，支持Unicode的XML处理

Question

我正在开发Delphi 7（个人版）。我曾经使用JvSimpleXML进行XML处理，但它似乎没有处理WideStrings（或者它呢？！）。我的整个项目使用了TntWide ......＆amp; SpTBXLib用于接口，因此它可以很好地处理Unicode，我现在需要在文件中存储一些设置...所以我正在寻找解决方案或（免费）替换JvSimpleXML ......任何想法？

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

以下是代码生成的示例

// *********************************************************************//
// Interface: IXMLDOMDocument
// Flags:     (4560) Hidden Dual NonExtensible OleAutomation Dispatchable
// GUID:      {2933BF81-7B36-11D2-B20E-00C04F983E60}
// *********************************************************************//
  IXMLDOMDocument = interface(IXMLDOMNode)
    ['{2933BF81-7B36-11D2-B20E-00C04F983E60}']
    function Get_doctype: IXMLDOMDocumentType; safecall;
    function Get_implementation_: IXMLDOMImplementation; safecall;
    function Get_documentElement: IXMLDOMElement; safecall;
    procedure _Set_documentElement(const DOMElement: IXMLDOMElement); safecall;
    function createElement(const tagName: WideString): IXMLDOMElement; safecall;
    function createDocumentFragment: IXMLDOMDocumentFragment; safecall;
    function createTextNode(const data: WideString): IXMLDOMText; safecall;
    function createComment(const data: WideString): IXMLDOMComment; safecall;
    function createCDATASection(const data: WideString): IXMLDOMCDATASection; safecall;
    function createProcessingInstruction(const target: WideString; const data: WideString): IXMLDOMProcessingInstruction; safecall;
    function createAttribute(const name: WideString): IXMLDOMAttribute; safecall;
    function createEntityReference(const name: WideString): IXMLDOMEntityReference; safecall;
    function getElementsByTagName(const tagName: WideString): IXMLDOMNodeList; safecall;
    function createNode(type_: OleVariant; const name: WideString; const namespaceURI: WideString): IXMLDOMNode; safecall;
    function nodeFromID(const idString: WideString): IXMLDOMNode; safecall;
    function load(xmlSource: OleVariant): WordBool; safecall;
    function Get_readyState: Integer; safecall;
    function Get_parseError: IXMLDOMParseError; safecall;
    function Get_url: WideString; safecall;
    function Get_async: WordBool; safecall;
    procedure Set_async(isAsync: WordBool); safecall;
    procedure abort; safecall;
    function loadXML(const bstrXML: WideString): WordBool; safecall;
    procedure save(destination: OleVariant); safecall;
    function Get_validateOnParse: WordBool; safecall;
    procedure Set_validateOnParse(isValidating: WordBool); safecall;
    function Get_resolveExternals: WordBool; safecall;
    procedure Set_resolveExternals(isResolving: WordBool); safecall;
    function Get_preserveWhiteSpace: WordBool; safecall;
    procedure Set_preserveWhiteSpace(isPreserving: WordBool); safecall;
    procedure Set_onreadystatechange(Param1: OleVariant); safecall;
    procedure Set_ondataavailable(Param1: OleVariant); safecall;
    procedure Set_ontransformnode(Param1: OleVariant); safecall;
    property doctype: IXMLDOMDocumentType read Get_doctype;
    property implementation_: IXMLDOMImplementation read Get_implementation_;
    property documentElement: IXMLDOMElement read Get_documentElement write _Set_documentElement;
    property readyState: Integer read Get_readyState;
    property parseError: IXMLDOMParseError read Get_parseError;
    property url: WideString read Get_url;
    property async: WordBool read Get_async write Set_async;
    property validateOnParse: WordBool read Get_validateOnParse write Set_validateOnParse;
    property resolveExternals: WordBool read Get_resolveExternals write Set_resolveExternals;
    property preserveWhiteSpace: WordBool read Get_preserveWhiteSpace write Set_preserveWhiteSpace;
    property onreadystatechange: OleVariant write Set_onreadystatechange;
    property ondataavailable: OleVariant write Set_ondataavailable;
    property ontransformnode: OleVariant write Set_ontransformnode;
  end;

修改

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

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Microsoft网站：

  

MSXML4是为了添加功能而引入的   并提高了性能但一直如此   被MSXML6取代。客户   MSXML4应该考虑迁移到   MSXML6只要有计划约束   允许。

Delphi附带的TXMLDocument处理WideStrings / Unicode就好了。默认情况下，它使用此处提到的MSXML库。它是一个类似API的DOM。有关示例，请参阅http://delphi.about.com/library/weekly/aa101904a.htm。

Answer 3

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”。

Answer 4

经济实惠但不免费，存储库@ http://www.deepsoftware.com/rsllib/将保存为XML，IN，Registry等。

Answer 5

如果您需要检查XSD架构或使用XSL进行转换，则应该查看DIXml。
