Hi all,


with a tree like this:

   PROGRAMA (SET (...) EXECUTE (...))

I'm need to walk trought se subnodes o SET node, but not
trought the EXECUTE subnodes.

For this, i put this rule:



> programa: ^(PROGRAMA set EXECUTE);
> set: ^(SET ...);
>

the result is : [programa]: line 0:0 mismatched tree node: DOWN; expecting
type <UP>

In antlr 2 I could do  #(PROGRAMA set EXECUTE), Can i do it in antlr 3?

thank's
José Ventura
