Thanks for comments. I managed to figure out something what will do the trick for me. If anyone else is looking something similar, then I used the following approach:

select abc=STUFF((
select ' ' + b.n 
from (
    select ROW_NUMBER() OVER(order by n asc) as rn, n 
    from (
        select RIGHT('test data', LEN('test data') - CHARINDEX(' ', 'test data')) as n
        union all
        select LEFT('test data',  CHARINDEX(' ', 'test data')) as f
        ) a
     ) b order by rn asc
for xml path('')),1,1,'')
