sed: parsing tnsnames.ora

All:

Can sombodoy help me out with a sed command? Assume I have the following:
Code:
PRI =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 10.0.3.7)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = pri)
      (INSTANCE_NAME = pri)
    )
  )

STDBY =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 10.0.3.5)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = stdby)
      (INSTANCE_NAME = stdby)
    )
  )


AIXSNAP =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 10.9.0.5)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = aixsnap)
      (INSTANCE_NAME = aixsnap)
    )
  )


I would like to get the line right above (DESCRIPTION. Keep in mind that there may or may not be spaces between the '(' and the word DESCRIPTION. So valid examples can be something like this:

Code:
 
(DESCRIPTION= 
( DESCRIPTION= 
(DESCRIPTION  = 
(    DESCRIPTION = 

The output I am looking for should be like this
Code:
 
 PRI
 STDBY
 AIXSNAP

Thanks in advance to all who help!!!
