How to read a hexadecimal numbers and flip

I have a txt which is like

00 00 00 02 78 0B 09 00 DA 7F

00 00 00 02 78 0B 08 00 DB 7F

...

I am trying to flip like this

7F DA 00 09 0B 78 02 00 00 00

7F DB 08 0B 78 02 00 00 00 00

If I use fliplr directly which like this

F7 AD 00 90 B0 87 20 00 00 00

that is not what I want

Can anyone give me some hint or help?

str = "00 00 00 02 78 0B 09 00 DA 7F" ; 

str = fliplr(strsplit(str)) ; 
iwant = strjoin(str) ;
