Regex match folder and all subfolders
What about using | (or):
'.*/statistics($|/.*)'
Explanation:
.* # any length string
/statistics # statistics directory
($|/.*) # end of string or any string starting with /
It does the job and is not hard to comprehend. Tested with python re module.
Use following regex:
/^[^\/]+\/statistics\/?(?:[^\/]+\/?)*$/gm
