sed be thy friend. I didn't catch the beginning of the discussion, but 
if you append
| sed 's/.*STRING: //'

to whatever command you're running it should work pretty ok, although 
with decently recent tools you should also be able to pass -Ovq to 
snmpget and achieve pretty much the same result with less overhead.
