[antlr-interest] Tree structure

[ManimuthuLakshmi Pitchaikani]

Hi,
 
I want the tree structure as follows:
 
Nice  
     |
     |--15
 
My code is as follows:

opt_pri! :#(PRI priVal)

{

#opt_pri = #([NICE, "nice"], #priVal); 

}

;



priVal! : INT

{

#priVal = #[INT,"-15"];

}

;

 
Am getting the following error:

java.lang.Error: Unresolved compilation problem: 

priVal cannot be resolved

How i can resolve this error? Is there is any other way?

Thanks.

Best regards,

Lakshmi
