MathDOM is a set of Python 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.
