Apply XSL on HTML/MathML ?

Hello,

I'm trying to make MathML accessible for blind people (=transform MathML
tags into corresponding text chars for Braille display) through an XSL
stylesheet (I think XSL is the best solution, but i'm not sure...).
The problem is : I can apply a XSL sheet to an XML doc, but not to an HTML
doc, and Amaya (for example) produces HTML docs with MathML inside.
Does anybody knows a way to apply an XSL sheet on an HTML doc to tranform
only the MathML tags and leave the other HTML tags as they are ?

Thanks a lot for any reply,
Frederic Schwebel.
PS : another solution would be an XML editor with MathML support, but I
didn't find any (yet). Does anybody know one ? Thanks again.
