omml2mathml

Small utility to convert from Microsoft's OMML to MathML.

This is by and large a port of the the omml2mathml.xsl XSLT that Microsoft ships with Office and that is in relatively wide use, with a few bugs fixed. This implementation does not require an XSLT processor (I built it because I became tired of XSLT processors that crash)

Installation

npm install omml2mathml

API

The API is very simple: there is only one function to know, it takes one input, runs synchronously, and returns one output.

import omml2mathml from 'omml2mathml';
let mathmlElement = omml2mathml(oMathElement);

The input should be an m:oMath or m:oMathPara element. Note that you can always use the former even if it has an m:oMathPara parent and the module will correctly set display="block" all the same. The object does not need to belong to any specific DOM implementation, it just needs to support some basic DOM operations (roughyl DOM 2, and then again not all of it). For instance the xmldom module will work fine.

It returns an instance of a math element as an HTML DOM object, as produced through the get-dom module, which is to say that if you are running this in the browser it will be the browser's implementation; if in Node it will be jsdom.
