  You can put the grep before the loop (and you don't need the cat):

        grep cocoanuts <<XX |
        your test here
        XX
        while...

  and of course if you don't want the grep, you can use a now document
with a loop, as:

        while read foo; do
	  process $foo
	done <<XX
	your now documant
	contents here!
	XX

  Which I admit is not something I find useful every day.
