Here is a one-liner you can try. Interchange quotes(' vs ") if on Linux: 
perl -ne "next unless /ghjghjgkhgkghj/../fsgdfgsdfgdfsgdsfg/;chomp;pus
+h @l,$_;END{$r=join '', @l[1..$#l-1];print $r}" Your-file-name-here

Note the use of the flip-flop operator .. to select stuff between the tokens, and array slicing to avoid the delimiters.
