in reply to Second Time Replace Regex

xdg had some valid questions, but barring additional info, here's a one-liner (see perlrun) solution: 
perl -i -0777 -pe 's/(\bAAAA )(QQQQ)(PPPP)( BBBB\b.*?\bCCCC XXXX )\2\3
+\b/$1$2$3$4$2/sg' /tmp/f

[download]
Tested against this data: 
blah
stuff AAAA QQQQPPPP BBBB stuff
more stuff blah
and CCCC XXXX QQQQPPPP and more
stuff.
