[antlr-interest] Suggestion needed

[CK Ng]

I come across StringTemplate and it give me the following idea, can 
something like this be done? Anyone?

[my definition file]-->[parser < my definition grammar]-->AST

[AST above] --> [StringTemplate < template] --> [grammar 2]

[InputStream]-->[ parser < grammar 2] -->[output - obj]


Or is there other better approaches?

Regards,
CK Ng
