[antlr-interest] Match any node/subtree

[Thomas Vial]

Hi,

Is there a way to have a rule, in a tree grammar, match any node/subtree
whatever it is (like a wildcard)? Something like:

rule:
   ^(NODE child) { doSomething($child); }   // child is any subtree, no
subrule to match it explicitely


Thanks,

Thomas
