Question

I have a string from which I want to extract a certain part:

Original String: /abc/d7_t/g-12/jkl/m-n3/pqr/stu/vwx

Result Desired: /abc/d7_t/g-12/jkl/

The number of characters can vary in the entire string. It has alphabets, numbers, underscore and hyphen. I want to basically cut the string after the 5th “/”

I tried a few regex, but it seems there is some mistake with the format.

Answer 1

If a non-regexp approach is acceptable, how about this:

s.split('/').take(n).join('/')+'/'

Where s if your string (in your case: /abc/d7_t/g-12/jkl/m-n3/pqr/stu/vwx).

def cut_after(s, n)
  s.split('/').take(n).join('/')+'/'
end

Then

cut_after("/abc/d7_t/g-12/jkl/m-n3/pqr/stu/vwx", 5)

should work. Not as compact as a regexp, but some people may find it clearer.
