iRule function to get node IP address from node name

I'm trying to create a pool member status page like the one described at this link:

pool-member-status-page-on-a-virtual-server-v11

The command

for POOLNAME in `tmsh list ltm pool | grep -i "ltm pool" |  sort | awk '{print $3}'`; do
    for POOLMEMBER in `tmsh list ltm pool $POOLNAME | grep : | sort | awk '{print $1}'`; do
            echo \"$POOLNAME/$POOLMEMBER\", >> ${classfile}
    done
done

returns the pool name, the node name, and the port. It does not return the node IP address. But the LB::status method requires the pool member IP address, not the name. I could probably modify the code to return the IP address, but then I wouldn't have the node name and the port. I'm picky and I would like to have both because I want to display the name of the node/pool member on the web page so the users won't have to look up the IP address, plus the port is required for the LB::status method.
