I am trying to think of a validator that checks for Exception block available in PL/SQL block or any routine for the main body ( Highlighted in Bold).

Eg :

DECLARE
some data
      Procedure xyx IS
      BEGIN
      ....
      EXCEPTION
      ..
      END;  

BEGIN
some data
      BEGIN
      ....
      EXCEPTION
      ..
      END;  
**EXCEPTION**
some data
      BEGIN
      ....
      EXCEPTION
      ..
      END; 
END; 

This is a simple example there can be many other scenarios but my need id to find that Exception block is avaialble for the main block of PL/SQL code.

Please let me know if you have any suggestion. Thanks
