Repeating variable length segments in Regex

Question

I'm trying to match the following with this Regexp:

/(?<route>(?:.*\/){1,2}?)(?<group>(?:.*\/){1,2}+)?/

• route/group/
• route1/route2/group/group2/
• route/group1/group2/
• route/

Tried to make the first group lazy and the second one greedy and optional but it doesn't match. What am I missing?

Assuming there is a file extension at the end of the path then you could use:

(?<route>(?:[^/\s]*\/){1,2}?)(?<group>(?:[^/\s]*\/){0,2})(?=[^/]*\.)

If not then change \. to $ or whatever suits.
