Jim Thanks again for your answer.
1. I checked the DOTTreeGenerator.java code but I do not seem to know how it finds all the info about a tree. Also I am confused with its use of both the stringtemplates and trees (are'nt they mutually exclusive?). 2. Yes, the toStringTree() method prints the tree but it only gives the leaf nodes, that is the program itself. I have no info about which rule a given token belongs to. To be more clear, see the attached snapshot. My question is how can I capture this parse tree in a some kind of java data structure and walk through it. Many Thanks again for all your help.
