docx4j:帮助用MathML转换XHTML

Question

我正在使用docx4j-ImportXHTML来转换XHTML文件。现在我想增加数学(方程式)的支持。我知道我需要包含一个XSL样式表来将MathML转换为OMML，但是我不知道如何添加XSL处理。有人能提供任何指导吗？

如有任何帮助，我们将不胜感激！

类似于：

 } else if  (e.getNodeName().equals("math")) {
                   
                    // handle me
                    System.out.println("Handling mathml \n\r" + XmlUtils.w3CDomNodeToString(e) );
                   
                            try {
                            // Prepare to transform Element e
                            Source xsltSource  = new StreamSource(
                                            ResourceUtils.getResource(
                                                            "mml2omml.xsl")
                                            ); // https://raw.githubusercontent.com/Marti ... l2omml.xsl
                            /* You need to add the template:

                            // Use constructor which takes Unmarshaller, rather than JAXBContext,
                            // so we can set JaxbValidationEventHandler
