Hi Karim, > I am looking at some XSL stylesheet to transform Presentation MathML > to > Content MathML. > Can anyone provide me such a tool? As Michael has said, this kind of transformation is not easy to do for various reasons. If you can simplify or restrict the context you're working in, you may find that things become slightly more amenable. One thing I investigated recently was trying this kind of transformation on very simple Presentation MathML corresponding to the kind of basic algebraic expressions you might encounter in UK School or early FE/HE mathematics teaching, to investigate possible applications for e-Assessment at this level. Working within this very restricted domain simplifies the problem significantly, as did working solely on the Presentation MathML output of a LaTeX to MathML converter (SnuggleTeX) and/or the MathML generated by ASCIIMathML, since the resulting "source" Presentation MathML has a fairly well- defined structure. In my case, the conversion was done using a pipeline of two XSLT 2.0 stylesheets. The first converted the display-oriented Presentation MathML into something with a more "semantic" structure, and the second then converted this to Content MathML. (A third stylesheet also generates linear input format for the Maxima computer algebra system.) You're welcome to play around with these stylesheets to see if the approach might be useful for you. (I found XSLT 2.0 extremely powerful here for various reasons. E.g. I could define XPath functions for matching certain PMathML constructs, which made the code very expressive.) There are, of course, many caveats and limitations to this approach...!
