Question

i have a unique challenge.

i want to create a google analytics filter for a custom variable that only returns a value if the given string is smaller or equal than ‘001700’. yeah, i know that a string can’t be smaller, still i need to find a way to make this work.

oh, and if you ask: no there is no way to convert that string to a number (according to my knowledge – via a google analytics filter – and that is what i have to work with in this case).

so basically, i have

000000
000001
000002
000003
...
...
999998
999999

and i need a regular expression that matches

001700
001699
001698
...
...
000001
000000

but does not match

001701
001702
...
...
999998
999999

sub question a) is it possible? (as i have learned, everything is possible with regExp if you are clever and/or masochistic enough)

sub question b) how to do it?

thx very much

Answer 1

You can do:

^00(1700|1[0-6][0-9]{2}|0[0-9]{3})$

See it
