If I were in your case I would like to implement my own version of a declarative language, now days declarative languages (and functional languages also) are becoming the most popular, first because their usage is very simple, after because you write small code with them, and finally because the usage of XML is for now so extended. For example Microsoft XAML, XSTL, XSL-FO and my favorite JSTL:
Why you don't write some interpreter of JSTL, I don't think it could require the most complex code to be parsed, could it?
