[antlr-interest] How to Parse a datastream of tokens and values

[Weiler-Thiessen, David, SASKATOON, Engineering]

Hi 

 

I am trying to parse a string that is a collection of tokens and values.   For example:

PRCLINTON

 

Where PR is my token, and CLINTON is the value for the token.

 

I have started a simple grammar, see below, but it won't parse the sample above.

 

message              :               productionReceipt

                ;

                

productionReceipt

                :               PR VALUE

                ;

                

PR           :               'PR'

                ;

                

VALUE  :               ('a'..'z'|'A'..'Z')+

                ;

 

 

What am I doing wrong?  I get a MisMatchedTokenException in ANTLRWorks.
