[antlr-interest] Parsing Trees & Tree Grammars

[Carter Cheng]

Hi,

I have been hoping to better understand the theoretical basis for parsing trees and doing tree transformations like what is done with Tree Grammars and Tree Walkers in ANTLRv3. Does anyone have any suggested reading which could be used to better understand the method choices and what is employed in this area?

Thanks in advance,

Carter.
