This should do the trick:

([^/?]+)(?=/?(?:$|\?))

See it here in action: http://regexr.com?322bq

Explanation:

  • ([^/?]+) - Matches any characters that are not a slash or a question mark.
  • (?= - Starts a look-ahead.
  • /? - Optionally matches a slash.
  • (?:$|\?) - Either matches a question mark, or asserts that we're at the end.
  • ) - Closes the look-ahead.

Note: In the demo, it's also matching after the ? character, since it's doing a global search. That shouldn't concern you though.
