Splitting a string by the delimiter [message #82666]

Hi,
Is there any function available in oracle to split a string by the delimiter.
i.e. If the string is
,,NETHERLANDSANTILLES ,0.366,0.0122,0.366,0.0122,0.366,0.0122
--I want to split the above string by commas.
(The number of commas might be varying in the real case)

Thanx in advance
~V~

I have a 10-15 lines script which does what is required.

Test Db>@t
Input truncated to 1 characters
Field Value =
Field Value =
Field Value = NETHERLANDSANTILLES
Field Value = 0.366
Field Value = 0.0122
Field Value = 0.366
Field Value = 0.0122
Field Value = 0.366
Field Value = 9.0999
#Number of columns := 9

PL/SQL procedure successfully completed.
