Regular expression?

Hi Guys

I'm trying to add a regular expression to auto action
It should match for
a year between 2011 and 2100 OR a text, so I built this as a first, simple attempt:
(2[0|1]\d{2}|Text)

But I don't see that it matches in CB.
Also, I want to make sure that it always matches from the start.

What am I doing wrong?

I think one of my problems is that it's a multiselect field, so I guess I should enable it to contain more than one pattern, something like
((20[0-9]{2})|Æresmedlem)+

But I still can't make it match

REGEX doesn't work too well for matching date ranges. For example your current REGEX will match between 2000-2099. You may want to try 2(?:0[0-9]{2}|100) to give 2000-2100.

Multi-selects always store to database as delimiter divided. Example as follows.

value1|*|value2|*|value3

Your REGEX also has no delimiter so it'll never execute properly and your site when trigger is actually erroring out. Example as follows.

/((?:2(?:0[0-9]{2}|100))|(?:Text))+/

A good REGEX resource can be found at the below link.

Hi Kyle

Thanks for the link.

Do you know of a good tester I can use to test my expressions?
How do I test for an empty string or text (single select), ie. so it matches
""
"Ikke medlem"

But not
"Senior"
"Junior"
"Æresmedlem"
"Støtte"

I was thinking
/(?:Ikke medlem)/

But that doesn't seem to trigger on empty?

Several free online solutions available with a quick Google search. Examples as follows.

Personally I use RegexBuddy, which is a commercial product (well worth it if you use REGEX/GREP regularly).
