Unclear what you want
Your example appears to be inconsistent to me. In the case of 1, you remove the www and in the case of 2, you don't. Please explain or do you mean that
--------------------------
1 aaa xxx 55
--------------------------
1 aaa www 32
--------------------------
2 bbb yyy 11
--------------------------
2 bbb zzz 34
-------------------------
2 bbb ttt 45
---------------------------
...
should go to
-------------------------
1 aaa xxx 55
www 32
-------------------------
2 bbb yyy 11
zzz 34
ttt 45
-------------------------
...
or to:
-------------------------
1 aaa xxx 55
aaa www 32
-------------------------
2 bbb yyy 11
bbb zzz 34
bbb ttt 45
