Exclusive Or in Regular Expression

regex, xor

Solution

You can do this with a single regex but I suggest for the sake of readability you do something like...

(/foo/ and not /bar/) || (/bar/ and not /foo/)

Problem

Looking for a bit of regex help. I'd like to design an expression that matches a string with "foo" OR "bar", but not both "foo" AND "bar" If I do something like... ``` /((foo)|(bar))/ ``` It'll match "foobar". Not what I'm looking for. So, how can I make regex match only when one term or the other is present? Thanks!
