Subject: Re: Hash :: Recursive traversing and stripping the values

Hi Guys,

  I found out another way to do this using a 'lambda' function
  I am just curious to know, how effective is this compared to the
above mentioned suggestions

 
-----------------------------------------------------------------------------------
  Code modified from source http://blog.hasmanythrough.com/2008/6/20/recursive-lambda
 
-----------------------------------------------------------------------------------

  thunk = lambda do |key,value|
    case value
      when String then value.strip!
      when Hash   then value.each(&thunk)
      when Array  then value.each {|vv| vv.strip!}
    end
  end

  --------------------------------
  Call
  --------------------------------

  <Hash>.each(&thunk)

  Thanks,
  Vimal Das
  Waiting with curiosity :-|
