mml2sympy

A simple package for converting presentation math ML into sympy expressions.

Example

>>> from mml2sympy import mml2sympy
>>> mml = '''
...         <math xmlns="http://www.w3.org/1998/Math/MathML">
...           <mstyle displaystyle="true">
...             <mn> 2 </mn>
...             <mi> x </mi>
...             <mo> - </mo>
...             <mn> 4 </mn>
...             <mo> = </mo>
...             <mn> 7 </mn>
...           </mstyle>
...         </math>
...     '''
>>> expression_strings = mml2sympy(mml)
>>> expression_strings
["Eq(Add(Mul(Integer(2),Symbol('x'),),Integer(4),),Integer(7))"]
>>> from sympy import *
>>> expressions = [sympify(s, evaluate=False) for s in expression_strings]
>>> expressions
[Eq(2*x + 4, 7)]

Supports

Currently supports Add, Mul, Eq for sympy. Supports msup, mtable (one row support currently, no matrices, etc), mfrac, msqrt, mi, mn, mo.
