PL SQL with multiple inserts, how to continue after exception is raised

Question

Hi,
I have a simple PL SQL function with various inserts. ex:
Insert Into "DI01"."DUA_DIM_UNITE_ADMIN" (Ide_Unite_Admin_Sk, Num_Unite_Admin, Des_Unite_Admin) Values ('-1', '00000000', 'Défaut');
INSERT INTO "DI01"."DUA_DIM_UNITE_ADMIN" (IDE_UNITE_ADMIN_SK, NUM_UNITE_ADMIN, DES_UNITE_ADMIN) VALUES ('-2', 'S. O.', 'Sans Objet');
Insert Into "DI01"."DCU_DIM_CATGR_UNSPS" (Ide_Catgr_Sk, Num_Code, Des_Code, Num_Catgr, Des_C.........
I want to be able to run the function multiple times, and have all the inserts executed everytime, even if I get a ORA-00001 unique constraint (string.string) violated error in on of the inserts. That means that if I get an error in the first insert, I want the function to continue running and executing the consecutive inserts.
I though of including each insert in a different block, like:
BEGIN
Insert......
When Exception then null;
END;
BEGIN
Insert......
When Exception then null;
END;
But I have at least 50 inserts, so the final code becomes huge.
Another solution is to use merge inseat of insert, but the code seems too complex for such a simple task.
Is there any other solution for this that I am not seeing?
Thank you for your time,

You can use DML error logging approach or FORALL SAVE EXCEPTIONS.
Since you didn't mention the version I assume you are using 11g.
Below is the sample code for DML error logging mechanism
SQL> select * from v$version;
BANNER                                                                         
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production   
PL/SQL Release 11.2.0.3.0 - Production                                         
CORE 11.2.0.3.0 Production                                                     
TNS for Linux: Version 11.2.0.3.0 - Production                                 
NLSRTL Version 11.2.0.3.0 - Production                                        
SQL> DROP TABLE tableA;
Table dropped.
SQL> DROP TABLE Err$_tableA;
Table dropped.
SQL>
SQL> CREATE TABLE tableA
  2  (
  3     col1   NUMBER PRIMARY KEY,
  4     col2   NUMBER,
  5     col3   VARCHAR2 (10)
  6  );
Table created.
SQL>
SQL> -- Create error log table
SQL>
SQL> BEGIN
  2     DBMS_ERRLOG.create_error_log (dml_table_name => 'TABLEA');
  3  END;
  4  /
PL/SQL procedure successfully completed.
SQL>
SQL> BEGIN
  2     FOR i IN (SELECT 1 AS col1 FROM DUAL
  3               UNION ALL
  4               SELECT 1 FROM DUAL)
  5     LOOP
  6        INSERT INTO tableA (col1)
  7             VALUES (i.col1)
  8                LOG ERRORS INTO Err$_tableA REJECT LIMIT UNLIMITED;
  9     END LOOP;
10 
11     COMMIT;
12  END;
13  /
PL/SQL procedure successfully completed.
SQL> column column_name format a30
SQL> set linesize 300
SQL> select * from tableA;
SQL> select * from err$_tablea;
Thanks,
