Question

From any URL I want to extract its path.

For example:

URL: https://stackoverflow.com/questions/ask
Path: questions/ask

It shouldn’t be difficult:

url[/(?:\w{2,}\/).+/]

But I think I use a wrong pattern for ‘ignore this’ (‘?:’ – doesn’t work). What is the right way?

I would suggest you don’t do this with a regular expression, and instead use the built in URI lib:

require 'uri'

uri = URI::parse('http://stackoverflow.com/questions/ask')

puts uri.path # results in: /questions/ask

It has a leading slash, but thats easy to deal with =)
