latex string format of mathematical equation

[usharanicnp]

hi to all,

I am developing a desktop application which deals word documents. so need to display math formulas in jframe.
To do that, i need latex string format of math equation. can docx4j provides latex string format of math formula ??
pls help me out of this problem...

thank you..

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...

hi to all,

i am not understanding how to use "OMML2MML.XSL" (how to include in my java program)
pls share some code snippet.....

thank you in advance.

docx4j's XmlUtils contains:

    public static void transform(org.w3c.dom.Document doc,
                javax.xml.transform.Templates template,

                          javax.xml.transform.Result result) throws Docx4JException

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.

hi,

i have used the below code

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

my mmlstring output is :

i found mathml to latex conversion (java library). to do that mathml should be given below

<math>
<mtext>*******</mtext>
</math>

how can i convert omml to w3c supported mathml. pls help me.....

thanks in advance

An update: as of docx4j 17.0.4 (September 2026), the answer to the original question is simply yes — docx4j can now give you the LaTeX string of an equation directly, no OMML2MML.XSL, no MathML detour, no third-party MathML-to-LaTeX library.

The new docx4j-markdown module contains org.docx4j.markdown.math.OmmlToLatex:

Syntax: [ Download ] [ Hide ]

Syntax: [ Download ] [ Show ]

Using java Syntax Highlighting

String latex = new OmmlToLatex().convertOMath(oMath);  // m:oMath -> e.g. P=\frac{1}{2}\rho AU^{3}

Parsed in 0.013 seconds, using GeSHi 1.0.8.4

It covers a published LaTeX subset (fractions, sub/superscripts, radicals, sum/integral with limits, delimiters, matrices, aligned equations, accents, Greek and common symbols); an equation outside the subset throws rather than producing something silently wrong, so you can fall back to the equation's plain text. The translation also runs in reverse (LaTeX → native OMML), and if you want a whole document rather than one equation, Docx4J.toMarkdown exports it as Markdown with the equations as $...$ LaTeX.

If you'd still rather have MathML (e.g. for an existing MathML→LaTeX toolchain), that's native now too: org.docx4j.convert.out.mathml.OmmlToMathML, no Microsoft stylesheet required.

Details: CR-006 (TeX math ⇄ OMML) and CR-007 (OMML ⇄ MathML).
