Here is a RegEx that I am using to check if the given string is Hexadecimal or not.
/[^0-9a-fA-F]+/ #if this evals to true string is NOT hex I am having a trailing "+" to make sure at least one permissible character is present. Yet, it matches an empty string as a hex string. a) What am I missing? b) Why is an empty string being matched?
