[antlr-interest] Need help regarding parser

[elango m]

Hi,

We used a home grown hand written parser for parsing expressions, now I am
working on moving the hand written parser to ANLTR based parser. I have
written a grammar that well suits my requirement. But now I am facing an
issue.

In our parser we used to convert the following expression
NOT VAR1 = VAR2
to
NOT ( VAR1 = VAR2 )
while parsing (since the earlier one is wrong).

Now I want to do this with ANTLR. How do I do that?

Thanks in advance,
-EM-
