Code:
# awk 'BEGIN{FS="yyy"}{for(i=2;i<NF;i++) print $i}' file
 zzz sss aaa bbb
 xxx rrr sss ttt

check if this is what you are looking for:
Code:
perl -nl -e 'while (m/yyy(.*?)yyy/g) { print $1; }' file

it depends on what you want to do. You can do it inside awk, or outside in the shell
Code:
awk 'BEGIN{FS="yyy"}
{    for(i=2;i<NF;i++) {
           print $i
          #do something here
      }
}' file

until that information of what you want to do is spelt out, otherwise not much i can do
