Then, I'm not sure what you were pointing out here:

because my original solution and your solution result in the same 
output:


IO.foreach("data.txt") do |line|
  line.each(" ") do |word|
    print word.capitalize
  end
end

puts "*********"

File.foreach("data.txt") do |line|
  puts line.gsub(/\w+/) {|word| word.capitalize}
end


--input:---
the      Bourne    ultimatum
harry Potter    and    the Order of the phoenix
mission    impossible


--output:--
The      Bourne    Ultimatum
Harry Potter    And    The Order Of The Phoenix
Mission    Impossible
**********
The      Bourne    Ultimatum
Harry Potter    And    The Order Of The Phoenix
Mission    Impossible
