Regex Replacement BackReferences For Multiple Folders

Question

Given the following string:

/dh-jh-ng-fdhfjfk/djd-gkgi/700194015/image/test.png

Using:

^/[A-Za-z\-]+/[A-Za-z\-]+/[0-9{9}]/?(.*)?

I get the following backreferences:

R0: /dh-jh-ng-fdhfjfk/djd-gkgi/700194015/image/test.png
R1: 700194015/image/test.png

I need R1 to be:

R1: /image/test.png

"/image/test.png" can be any folder, multiple folders, any file, or none, in which case I need a single forward slash. How can I do this?

Note: This is for IIS re-write rules.

Answer 1

Get out of the range quantifier {9} from the character class , [{9}] would match a single character from the given list that is it matches { or 9 or } .

^/[A-Za-z\-]+/[A-Za-z\-]+/[0-9]{9}(/?.*)?
