this is what you are seeking for
s/\(.\{5\}\)\(..\)\(.*\)/\1XX\3/g
s = substitute
\( = start saving data in buffer1
. = any char
\{5\} = repeated 5 times
\) = end saved buffer1
\(..\) = save next 2 chars in buffer2
\(.*\) = save rest of line in buffer3
\1 = print buffer1
XX = insert XX after buffer1 = replace buffer2
\3 = print buffer3
