[om] OM class

[Cédric Vidrequin]

Hello Mike,

In fact, I'd like to transfor a string into an OpenMath (or MathMl) 
document.
I try to find a java class that do this, in the way to not develop it.
I have yet looked at the classes you talked about before, but I didn't 
find what I was looking for.
The XML file generated will be used in a personal application an not in 
Maple or Mathematica ...
That's why I think existing phrasebook will not help me.
Moreover, there are few coments and it's difficult for me to understand 
what each class is supposed to do.

Do you think you can tell me more about this problem ?

Regards,

Cédric VIDREQUIN
