update multiple rows continue past exceptions

I need to update as many rows as possible. The issue is that one row that fails causes the entire transaction to fail.

How do I get around this? I'd like to complete all UPDATE rows that don't have the exception. The below doesn't seem to work.

I'm using Oracle 10g

Thanks a bunch!

BEGIN
UPDATE MYTAB SET request = REPLACE(request, '$tpsToModify', 'tpsToModify') WHERE request like '%$tpsToModify%';  EXCEPTION
    when dup_val_on_index then

        dbms_output.put_line('DUPLICATE RECORD');
