Ok here is an idea how to do it in awk.

awk -v FS="|" '{ if ( $1 ~ /OBR/ ) print $4; }'

Could ofcourse be made more advanced if the mumber of | preceeding ORB
is changing.

Runs on the command line or inside vim (vi).
In vim:
:%! awk -v FS="|" '{ if ( $1 ~ /OBR/ ) print $4; }'

Hope it helped

Best regards
