[antlr-interest] Tree - Replace nodes in tree

[Des Hartman]

Is there a way that I can replace nodes in a tree with rewrite? I need to
completely replace the node and its child with a new node and child.
Something like:

LREF NAME -> ^(IREF NUM)

In effect replacing A with 1. I tried the above, but it seems to create a
child node of LREF.


Thanks
Des
