Thanks.
I intend to get following output:
02/10/2010;Illness expenses:Pharmacy;Test Pharmacy, Oakland;-19.1;

There may be another parent category where "Illness expenses" belongs
to, lets say "George". Then the output should be as follows:
02/10/2010;George:Illness expenses:Pharmacy;Test Pharmacy, Oakland;-19.1;

Thanks in advance,
George
