I am a newbie to scripting so I am probably missing something but when this function runs it just returns blank lines, but if I surround the sed with a print it returns the full commands that can be excuted on the command line

ne_ip_change() {

set -A NE `$CAT /tmp/ne_list`

COUNT3=`$CAT /tmp/ne_list | wc -l`

z=0
while [ $z -lt $COUNT3 ]
do

$SED -n '/ManagedElementId string=\"${NE[$z]}\"/,/ipAddress ip_v4/p' $XML | grep ipAddress | cut -f2 -d'=' | cu
t -f1 -d'/'`

((z=z+1))
done
}
