[SOLVED] Is there a better way of extracting certain data from xwininfo output?

hi,

Is there a simpler way of extractng some data from command output? Below is a partial output of xwininfo.

Absolute upper-left X: 430
Absolute upper-left Y: 136

I want to get the digits and format it like so:

430,136

I've used this command and it does the job. But it quite long.
Code:xwininfo | grep "upper-left" | head -n 2 | egrep -o "[0-9]+" | tr "\n" " " | awk '{ print $1 "," $2}'
430,136
Is there a better,shorter way of doing this?

Thx
