MathML 到 LaTeX 的转换 [英] MathML to LaTeX conversion

问题描述

我试图弄清楚如何转换数学方程的 MathML 表示并将其转换为该数学方程的 LaTeX 表示.比如……

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...

<math>
  <mrow>
    <mfrac>
      <mrow><mi>x</mi></mrow>
      <mrow><mi>y</mi></mrow>
    </mfrac>
  </mrow>
</math>

... 是一个简单的堆叠分数，它的 LaTeX 表示将是...

... is a simple stacked fraction and it's LaTeX representation would be...

frac{x}{y}

我保证 MathML 没有表示性标记，因为我正在动态构造 MathML 字符串并且我控制 MathML 元素的插入方式/位置；MathML 字符串只是数学方程的纯结构.

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.

所以我的问题是，是否有任何 Java/JavaScript 库可以采用 MathML 输入字符串(如上面的那个)并生成相应的 LaTeX 字符串?我宁愿不必自己编写这个解析器.如果不是 Java/JavaScript，是否有任何库可以做到这一点?

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?

如果没有，关于如何解决编写我自己的解析器这个问题的任何建议?从哪里开始、要考虑的事情、资源等...?

If not, any suggestions on how to approach this problem of writing my own parser? Where to start, things to consider, resources, etc...?

感谢 Optimal Cynic，我能够使用 这个 Java 库 来做我想做的事.然而，它并不完美，但我可以轻松地对其进行修改并使其正常工作.但是，我仍然希望在 JavaScript 中看到这一点.那么有没有像这样用 JavaScript 编写的工具呢?如果没有，我会自己翻译.

Thanks to Optimal Cynic, I was able to use this Java library 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.

注意:我正在使用 MathJax 在页面上呈现 MathML，但 MathJax 目前不支持一种从 MathML 到 LaTeX 的方法.它只能从 LaTeX 转到 MathML.

Note: I am using MathJax 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.
