Split a sentence by regular expression

ruby-talk
1

Hi
I want to split a sentence by means of regular expression.
For example, the sentence is
" Hello how r u?"

How can i split this ?

the way I used is as follows :

"

   matching = Array.new
   a = gets
   puts a.split.length

  re = /((\w+)\s)+/
  matching = re.match(a)
  i = 1
  until i >a.split.length

  puts i
  puts matching[i]
  #~ if (matching[i] == "u")
  #~ puts "Who is Anant?"
  #~ end
  i +=1

end

"

What does "split a sentence" mean? If it's just split around spaces, you could simply do

" Hello how r u?".split(' ')

or

" Hello how r u?".split(/\s+/)

if you want to remove empty words (i.e. ""s) you could do something like

" Hello how r u?".split(/\s+/).reject{|w| w == ""}

Does this answer your question?

Cheers,
Peter
