I think you meant.
while IFS= read -r cline; do

And even that's fancier than you may need for this particular task.
(Writing it with the process substitution forces the loop to run in
the current shell, so that you can set variables inside the loop and
have them survive. The pipeline alternative does not permit that.)

xargs is obtuse, hard to use, and fraught with peril.

imadev:~$ echo "don't" | xargs echo
xargs: missing quote?: dont

A shell loop is far more flexible, and doesn't break on inputs that
contain spaces and quotes.
