Regex to validate URI path with wildcard

I'm trying to validate entered URI path with wildcard pattern in a form of asterisks single(*) or double (**). For example: /path1/*/path2/ or /path1/path2/**/path3

I came up with regexp ^(?:\/\w+\/?|\/\*\/?|\/\*\*\/?)+$ that matches all valid path from the list below except: /foo* and /foo** and does not match invalid except one /foo//bar

Could you suggest a better regex to cover all cases and maybe more optimized than my.

Considering valid path like:

/foo/bar
/foo/bar/
/*
/foo/*
/foo/*/bar
/foo*
/**
/foo**
/foo/**
/foo/**/bar

and invalid path like:

foo
foo/bar
//foo
/foo//bar
/foo/***/bar
/***

Solution

You can use

^(?:/(?:\*{1,2}|\w+\*{0,2}))+/?$

See the regex demo

Details

^ - start of string
(?:/(?:\*{1,2}|\w+\*{0,2}))+ - one or more occurrences of
- / - a / char
- (?:\*{1,2}|\w+\*{0,2}) - one of the alternatives:
  - \*{1,2}| - one or two asterisks, or
  - \w+\*{0,2} - one or more word chars and then zero, one or two asterisks
/? - an optional /
$ - end of string.
