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TntWide ...和SpTBXLib作为接口，因此它可以很好地处理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michal

Answer 1

结帐OmniXML。我已经开始使用它而不是msxml。它还为您提供非常光滑的'FluentXMLBuilder'。

您可以使用从delphi导入dll的最新版本的qazxsw poi（Microsoft XML Core Services）。

MSXML 6

以下是生成代码的示例

位于XMLDoc.pas中的对象TXMLDocument（用于delphi 7）是MSXML 4或更少版本的包装器。

MSXML4是为了增加功能和提高性能而引入的，但已被MSXML6取代。 MSXML4上的客户应该在计划约束允许时立即查看迁移到MSXML6。

Answer 3

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Microsoft。

Answer 4

存储库@ qazxsw poi经济实惠但不免费，将保存为XML，IN，Registry等。

如果您需要检查XSD架构或使用XSL进行转换，您应该查看http://delphi.about.com/library/weekly/aa101904a.htm。
