ruby on rails - Regex that gets only initials -

is there way create regex initials without using references? example, want initials

new.york

and regex output

n.y. (or n.y)

so far have following:

.\.[a-za-z]+

this outputs last initial of first word instead of first initial: w.y.

update**

i'm assigned regexp variable , using =~ test things.

you remove lowercase letters using gsub function,

irb(main):004:0> str = "new.york" => "new.york" irb(main):006:0> str.gsub(/[a-z]+/, "") => "n.y"
