I need to convert mediawiki into LaTeX syntax. The formulas should stay the same, but I need to transform, for example = something = into \chapter{something}.

Although this can be obtained with a bit of sed, things get a little dirty with the itemize environment, so I was wondering if a better solution can be produced. Anything that can be useful for this task ?

This is the reverse of this question (graciously copied). Pandoc was the answer to that question, but probably not yet for this.
