how to marshal CTOMath

[yufeng0528]

hi all.
my goal is transfrom omml to mathml. and i do a lot of search, get the steps below:
1:get the math Dom, and to Node
2:use Transformer to mathml by OMML2MML.XSL
But I stunk in the first step.

this is my code. It throw exception in line 2:JAXBContext.newInstance.
could anyone tell me how to fix , or other ways to my goal.
thanks in andvance

                        CTOMath ctoMath = (CTOMath)((JAXBElement) o).getValue();
                        JAXBContext context = JAXBContext.newInstance(CTOMath.class, ObjectFactory.class, org.docx4j.wml.ObjectFactory.class);               
                       
                        DOMResult res = new DOMResult();
                       
                        Marshaller marshaller = context.createMarshaller();
                        marshaller.marshal(ctoMath, res);
                       
                       
                       System.out.println(res.getNode().getNodeName());
                       
                        Transformer transformer = TransformerFactory.newInstance().newTransformer(new javax.xml.transform.stream.StreamSource("/Users/trymore/Downloads/OMML2MML.XSL"));

                       
                        DOMSource ds = new DOMSource(res.getNode());
                        StringWriter writer = new StringWriter();
                        StreamResult sr = new StreamResult(writer);

                        transformer.setOutputProperty(OutputKeys.INDENT, "yes");
                        transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");
                        transformer.setOutputProperty(OutputKeys.METHOD, "xml");
                        //convert ooml to mathml
                        transformer.transform(ds,sr);

                        String mmlString=writer.toString();

ok，i have resolved.

Code: Select all

JAXBContext context = documentPart.getJAXBContext();//JAXBContext.newInstance(CTOMath.class, ObjectFactory.class, org.docx4j.wml.ObjectFactory.class);
                        ObjectFactory mathFactory = new ObjectFactory();
                       
//                        System.out.println(XmlUtils.marshaltoString(mathFactory.createOMath(ctoMath), context));
                       
                        System.out.println(XmlUtils.marshaltoString(mathFactory.createOMath(ctoMath)));
                       
                        DOMResult res = new DOMResult();
                       
                        Marshaller marshaller = context.createMarshaller();
                        marshaller.marshal(mathFactory.createOMath(ctoMath), res);

Sorry for the delay in replying; I've been busy with customers...

See https://github.com/plutext/docx4j/blob/ ... mulae.java for a worked example.
