​How to use SED command(s) that will replace the shell's pipe command in
order to perform more efficient, e.g:

echo abcde​ | sed -r 's/cd/XX/' | sed 's/[^x]/z/ig'

become far more efficient and compact, might be look like this,

echo abcde​ | sed -r 's/cd/XX/ {N: s/ ...........    }

( ...so on. That's what I am asking for )

both will give the same result   zzXXz
