[antlr-interest] Print an AST in original order

[Varun Bhargava]

Hi All,

 

I'm using ANTLR3 for C# target. My problem is to load up a statement
into a tree, so some substitutions to the tree and then print out the
tree in original order to re-generate the input statement but with some
substitutions.

 

I cannot seem to print the AST in its original order. For EG;

 

          WHERE

              |

             AND

           /       \

        =           =

      /   \        /  \

     A    5      b    10

 

 

The above tree should be printed as WHERE A=5 AND b = 10

 

However this is not the case in ANTLR. Has anyone done this before? If
yes could you please point me in the right direction or give me some
sample code?

 

Thanks

Varun
