Solution 1:[1]

I believe that this should do it: /[^\s\|]+/g and use the g global flag.

Solution 2:[2]

You should use a quantifier to repeat the character class one or more times like [^\s|]+

A negated character class matches not what you have listed in the character class and is kind of a broad match.

Another option is to be specific about what you do want to match. If you only want to match uppercase characters and an underscore, you could use [A-Z_]+ or match 1+ times a word character \w+
