[antlr-interest] Error with date

[Jan van der Ven]

Dear list,


I am taking my first steps with v3 (I have been working with 2.7 
before). I use AntlrWorks and have created the following snippet:

DIGIT    :    '0'..'9';
 
INT: DIGIT (DIGIT)*;

timestamp
    :    day '/' month '/' year ;
    
day    :    INT;

month    :    ('Jan' | 'Feb' | 'Mar' | 'Apr' | 'May' | 'Jun' | 'Jul' | 
'Aug' | 'Sep' | 'Oct' | 'Nov' | 'Dec');

year    :    INT;

When I feed it with: 09/Feb/2003 it matches the 09 and then tries to 
match Feb/2003, which of course fails: line 3:21 mismatched input 
'Feb/2003' expecting set null.

Can anyone explain this for me?

Kind regards,


Jan
