You can use 

getfield
function also to match the column if the position is known.

Example: XXX-GHDF-12XD45

        set eidval {XXX-GHDF-12XD45}
        set val [getfield $eidval "-" 3]

OR

        set spr "XXXA-GHDF-12XD45"
        set sub_spr [string range $spr [string last "-" $spr]+1 end

I also watched 

getfield
command but didn't find how to say the last field.
