HI there people,
Crikey, feels like ages since i've posted on here, hope as everyone is having a good time :)
Business:
Simple regex:
^[A-Z]/[A-Z]{2}[0-9]{3}/[0-9]{2}$
This checks for - AP/PD123/13, how can I change this to add an either or type operator in there, sort of like this:-
^[A-Z]/[A-Z]{2}[0-9]{3}/[0-9]({2}|{3})$
I'm sure that this is correct, but it's not reacting to the change.
?
Thanks in advance.
Cheers,
MRb

Beginning ^[A-Z]/ it does NOT match two letters, only one.
"two or three digits" is done with [0-9]{2,3}
Welcome back!

Hi there g1smd,
Sorry, that was down to sloppy copy n pasting!
Thanks for the solution there too, I'm not brilliant at doing regex & I thought as the | would work like it does in C. There I go assuming again lol!
Thanks for the welcome back there too.
Cheers,

/([0-9]{2}|[0-9]{3})$
would work, but the general rule is "when something repeats, stuff can be combined", hence
/[0-9]{2,3}$ instead.

Hi g1smd,
I've just tested it, and it works great; I opted for the 'short-hand' version, and I've now combind an array of possible combinations down to 4 opposed to 8.
Thanks for the help once again!
Cheers,
MRb

There was a longer thread about combining things only yesterday or the day before.
Might be some extra clues in there too!
