Text Parse on SNMPGet

[WeAreGray]

hello,
I am trying to parse the response I receive to an SNMPGET. Below is a list of some strings that I get. What I would like to do is to condense the string down so that "WS-F6700-DFC3BXL Distributed Forwarding Card 3 sub-module of 1" becomes "DFC Sub-Module of 1". Is this possible, and if so, how?

Thank You

WS-F6700-DFC3BXL Distributed Forwarding Card 3 sub-module of 1
WS-F6700-DFC3BXL Distributed Forwarding Card 3 sub-module of 2
WS-F6700-DFC3BXL Distributed Forwarding Card 3 sub-module of 3
WS-F6700-DFC3BXL Distributed Forwarding Card 3 sub-module of 4
WS-F6K-PFC3BXL Policy Feature Card 3 sub-module of 5
WS-F6K-PFC3BXL Policy Feature Card 3 sub-module of 6

I'm not sure but maybe this helps a bit..

I don't know how to add custom string (like "DFC") as value.
