Generating output is usually the responsibility of the parser or 
tree parser, yes.  But if your input language is simple enough 
then there's no particular reason why you *couldn't* do all the 
work in the lexer, if you wanted to.

(Of course, if your input language is simple enough for that to be 
a viable option, there's a good chance that it's simple enough 
that using ANTLR or any other parser generator is just overkill.)
