Hi Team

I am looking for a regular expression to match 3 pre-defined values under a simple string attribute of type text.
The requirement is to enter either of the three values:
Required, Not Required, Done

I have written the below expression to validate:
(^|\s)Required|Not Required|Done(\s|$)

This works only for the first value.
If I enter the same value or different value on the new line; it gives me an error.

Please let me know what am I missing here.

Thanks
Rajat

Managed to get the following expression working


((Done)\n|(Required)\n|(Not Required)\n){0,3}

However it is case sensitive even if we remove the check mark from the validator.

Any suggestions??

Use the "i" switch.

 Thanks but it does not work when using \n.

I have entered regular expression as:
((Required)\n|(Done)\n|(NotRequired)\n){0,7}

Could you give me an example as to how can 'i' switch work on this.

Regards
Rajat
