[antlr-interest] Tree Parser and removing nodes.

[ooobles]

I have a tree parser which I'd like to automatically create basically
the same output tree with a few modifications. One of the changes is
to move a list of child AST's into a parent list.

eg. I have token A:(B|C)*; and C:(B)*;

A
  B
  C
    B
    B
  B

I'd like to remove occurances of C and leave

A
  B
  B
  B
  B

with the children of B moved up to become children of A.

I'm assuming this has a simple answer that I'm not seeing?
