It sounds like awk might be better suited to what you want to do than
sed.
You should be able to do something like this with sh and awk:
cat test.txt | awk -F'|' '{ print $1,$2,$3 }' | \
while read VAR1 VAR2 VAR3; do
# do something with $VAR1, $VAR2, and $VAR3
done
So if test.txt contains
a|b|c
d|e|f
On the first iteration of the while loop, VAR1=a, VAR2=b, and VAR3=c,
and on the second iteration... well, you get the idea :)
