xerces2-j - 如何配置 xerces 自定义 xincludehandler

Question

我使用自定义 XIncludeHandler 类的新实例在 Xerces 解析器配置上设置了“http://apache.org/xml/properties/internal/xinclude-handler”属性。然后，我使用该配置创建一个新的 SAXParser。我通过在配置和解析器上调用 getProperty() 来验证自定义 xincludehandler 是否已安装。

xinclude 处理已启用。

但是当我调用 parse() 时，解析器使用默认的 XIncludeHandler 类，如默认处理程序发现无效的 href 属性（我的自定义处理程序应该拦截和修复）时发出的堆栈跟踪所示。

  XML11Configuration parserConfig = new XIncludeAwareParserConfiguration();
  parserConfig.setProperty(
      "http://apache.org/xml/properties/internal/xinclude-handler",
      new XIncludeHrefFixer());
  XMLReader parser = new SAXParser(parserConfig);

我已经在 v2.12.0、2.12.1 和 2.9.1 中确认了这种行为。

堆栈跟踪的相关部分是：
