A very natural thing to do is to write a small library of functions in Maple or Mathematica such as, for example Plus := proc(a,b) a + b end; and then use your XSLT to write Plus(a,b) instead of a+b. Also, both systems import MathML and so can be used to re-write it after importing the original XML expression. I would not try to write an algebraic simplifier in XSLT since in priniciple this is as hard as writing an algebra system and it is probably the wrong implementation language - but you already seem to be on the track of using the right tools anyway. :-) Stan Devitt Ana Skupch wrote: >Hi! > >I'm looking for a way to correct/simplify mathematical expressions encoded in MathML.
