I want to get the AST from the parser. I set the option "output=AST;" and saved the return object from the parser.
Now I would like to walk (DFS) through the tree. But using the getChild(i) method gives me only the tokens of the leafs. Where are the other nodes between root and leafs? I also tried:
CommonTreeNodeStream nodes = new CommonTreeNodeStream(tree);
But nodes.toString() also returns only the tokens. Is there any way to get the entire AST, without writing a new grammar for a tree walker?
Thank you very much for any reply !!!
