  1. POMathML to LaTeX conversion
    text
    copied!<p>I'm trying to figure out how to convert a MathML representation of a math equation and convert it to the LaTeX representation of that math equation. So for example...</p> <pre><code>&lt;math&gt; &lt;mrow&gt; &lt;mfrac&gt; &lt;mrow&gt;&lt;mi&gt;x&lt;/mi&gt;&lt;/mrow&gt; &lt;mrow&gt;&lt;mi&gt;y&lt;/mi&gt;&lt;/mrow&gt; &lt;/mfrac&gt; &lt;/mrow&gt; &lt;/math&gt; </code></pre> <p>... is a simple stacked fraction and it's LaTeX representation would be...</p> <pre><code>\frac{x}{y} </code></pre> <p>I'm guaranteed that the MathML has no presentational markup because I am constructing the MathML string dynamically and I control how/where the MathML elements are inserted; the MathML string is just pure structure of the math equation.</p> <p>So my question is, are there any Java/JavaScript libraries out there that can take a MathML input string, like the one above, and generate the corresponding LaTeX string? I would much rather not have to write this parser myself. If not Java/JavaScript, are any libraries at all that can do this?</p> <p>If not, any suggestions on how to approach this problem of writing my own parser? Where to start, things to consider, resources, etc...?</p> <h2>UPDATE</h2> <p>Thanks to <a href="https://stackoverflow.com/users/541451/optimal-cynic">Optimal Cynic</a>, I was able to use <a href="http://www.tilman.de/programme/mathparser/download_en.html" rel="nofollow noreferrer">this Java library</a> to do what I want. It is not perfect however, but I can easily modify it and make it work well. However, I would still like to see this done in JavaScript. So are there any tools like this written in JavaScript? If not, I'll resort to translating it myself.</p> <p>Note: I am using <a href="http://www.mathjax.org/" rel="nofollow noreferrer">MathJax</a> to render the MathML on the page, but MathJax does not currently support a way to go from MathML to LaTeX. It can only go from LaTeX to MathML.</p>
