Ok, I solved it, but got another problem in return.
The parser matched the Feb/2003 to ID2
ID2 : ('a'..'z' |'A'..'Z' |'_' ) ('a'..'z' |'A'..'Z' |'_' |'0'..'9' |
':' | '#' | '.' | '-' | ' ' | '/' )* ;
And if I remove the / from this definition, my timestamp is parsed
correctly.
But not all my ID's.
I have several sort of ID's: some allow all characters, and some are
more strict.
How would that be done?
Kind regards,
Jan
