Subject: Re: Split a sentence by regular expression

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
