Request help for Extracting CLOB String

Question

Hi Everyone,
I am getting the input string in the form of CLOB delimited by '~'. I have to tokenize the string and insert those values into the below table through procedure / function.
Create table TEST_TEMP ( NUM NUMBER(10),
NAME VARCHAR2(1000),
DESCRIPTION CLOB,
VALIDATION CLOB,
CREATED_DATE DATE,
COMPLETED VARCHAR2(1),
USER NUMBER(3));
For example the input string would be '11~test~sdfsdfsd~ewrerwerwerw~2007-10-10 13:00:00~Y~123'
Can you suggest any ideas / links how to do this?
Thanks

You can use this select to extract the values:
michaels>  with test1 as (
  select '11~test~sdfsdfsd~ewrerwerwerw~2007-10-10 13:00:00~Y~123'  str from dual union all
  select '12~test2~sdfsdfsd~ewrerwerwerw~2007-10-11 13:00:00~Y~123'     from dual)
select t.column_value.extract('s/s[1]/text()').getnumberval()  num,
       t.column_value.extract('s/s[2]/text()').getstringval()  name,
       t.column_value.extract('s/s[3]/text()').getclobval()  description,
       t.column_value.extract('s/s[4]/text()').getclobval()  validation,
       to_date(t.column_value.extract('s/s[5]/text()').getstringval(),'yyyy-mm-dd hh24:mi:ss')  created_date,
       t.column_value.extract('s/s[6]/text()').getstringval()  completed,
       t.column_value.extract('s/s[7]/text()').getnumberval()  "USER"
  from test1, table(xmlsequence(xmltype('<s><s>' || replace(str,'~','</s><s>') || '</s></s>').extract('s'))) t
       NUM NAME  DESCRIPTION      VALIDATION               CREATED_D COMPLETED        USER
        11 test  sdfsdfsd         ewrerwerwerw             10-OKT-07 Y                 123
        12 test2 sdfsdfsd         ewrerwerwerw             11-OKT-07 Y                 123
