Your description is a bit ambiguous.  Whitespace is defined as being one
or more spaces, tabs, etc.  Thus, you cannot have two adjacent instances
of whitespace.  Please clarify whether:

  *  any of the whitespace characters is other than a space (blank)
  *  the number of whitespace characters between the fields varies
  *  the fields are bounded within certain column positions

This will help us in assisting you.
