(It would help if you got rid of those html codes and provided text.)

>sar 1 | grep -v -e 'usr' -e 'HP' | tr -d '\n'| awk 'NF==5 {total=$2+$3} END {print total}'

This takes a sample after 1 second.

Removes lines with usr or HP.  (Most likely the title/header lines.)

Deletes all newlines.  (I'm not sure why since awk can total up columns?)

If there are 5 fields, add field 2 and 3 (user and sys times) and print a total after reading all of the(1) lines.
