a='I want THAAAAAT APPPPPLE ):):):'
s=regexp(a,'\s+','split')

But one problem sir,
The input file is ,
a='I want THAAAAAT APPPPPLE ):):): totally unprepared'
In this input we get
out =
'THAAAAAT' 'APPPPPLE' '):):):' 'totally' 'unprepared'
But the required output is,
out =
'THAAAAAT' 'APPPPPLE' '):):):'
how to solve this problem.
thank you sir.
