Hello!
I have a problem with the following expression: [X0-9][0-9]{4}
IMHO the string X1234 should match the expression, but RegExp 1.2 does not
think so...;-(
When I use the expression: [0-9X][0-9]{4} instead, everthing works as
expected.
But IMHO the expressions should be equivalent.
What is wrong?
Regards
Oliver
