You're right, modifying a generated file is not the thing to do.
Here's a simple solution that solves your problem: a custom lexer.
You write something like:
public class SomeLexer extends Lexer
... /* constructor, ...*/
/* Filter */
protected void filter()
if (token instanceof TString)
String text = token.getText();
int length = text.length();
token.setText(text.substring(1, length - 2));
This way, you won't need to modify generated code anymore.
