You could use regex you could also, if the data is a string or an array,
split them into a char array

e.g. :
s = "    hello"
s = s.chars.to_a
=> [" ", " ", " ", " ", "h", "e", "l", "l", "o"]

s.each do | c |
  if( c == " " )
    i = i+1
    puts i
  end
end

and that'll count the number of spaces.
