You could try omml to mathml to latex.

For omml to mathml, see further http://stackoverflow.com/questions/2570 ... -word-docx

For mathml to latex, Google provides plenty of info.

Let us know how you go...

thank you in advance.

docx4j's XmlUtils contains:

Syntax: [ Download ] [ Hide ]

Syntax: [ Download ] [ Show ]

Using java Syntax Highlighting

    public static void transform(org.w3c.dom.Document doc,
                javax.xml.transform.Templates template,
                          Map<String, Object> transformParameters,
                          javax.xml.transform.Result result) throws Docx4JException
   
    public static void transform(javax.xml.transform.Source source,
                                          javax.xml.transform.Templates template,
                                          Map<String, Object> transformParameters,
                                          javax.xml.transform.Result result) throws Docx4JException

    public static Templates getTransformerTemplate(
                          javax.xml.transform.Source xsltSource) throws TransformerConfigurationException

 

Parsed in 0.015 seconds, using GeSHi 1.0.8.4

You can study how docx4j uses these for its XHTML and XSL FO output.

But basically, you make a Templates object out of OMML2MML.XSL

And you'd marshall your OMML to org.w3c.dom.Document or create javax.xml.transform.Source from it.

Then invoke transform. javax.xml.transform is standard java stuff, so questions about that are best asked on StackOverflow etc.

TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer(new javax.xml.transform.stream.StreamSource("res1/input/OMML2MML.xsl"));
