MathDOM is a set of Python 2.4 modules (using PyXML_ or lxml_, and
pyparsing_) that import mathematical terms as a `Content MathML`_
DOM. It currently parses MathML and literal infix terms into a DOM
document and writes out MathML and literal infix/prefix/postfix/Python
terms. The DOM elements are enhanced by domain specific methods that
make using the DOM a little easier. Implementations based on PyXML and
lxml/libxml2 are available.
