Regex exact match of multiple strings within string

Question

I have an string of |DOGS|MAN|CAT| and I need to check that DOG and CAT exist in the string.

The input string is always split between pipes.

I have this at present:

((^|, )(?=.*\|DOG|\b.$)(?=.*\|CAT\b).*$)

This almost works, if my input string was |DOG|MAN|CAT| it is fine but as I have specified DOGS not DOG it should not match

Is your input string always pipe-delimited? I'm not entirely clear on what your possible inputs are. — ggorlen

if (/^(?=.*\|CAT\|)(?=.*\|DOG\|)/.test("|" + s + "|") { return true; } — Wiktor Stribiżew

This RegEx might help you to create a group, where you can list all your desired target string in it using a | (OR), and you may not bound it from left and right, if possible:

\b(DOG|CAT|ANYTHING|ELSE|THAT|YOU|WISH)\b

The first one works if needing to match either DOG or CAT which is another thing i need to do. the second doesn't fit my needs as it matches CAT when in the pipes it is CATS. Thank you though, the first is usefule
