Get the tnsnames.ora alias for a given service name

Hello,

puzzling me now way to long....so hopefully someone has the answer at hand:
The following shows a sample tnsnames.ora from another topic.
What I want to get as result the tnsnames alias "PRI" when searching for the service name pri.
That is, the left hand side of the tnsnames entry where the service name 'pri' is used.
Preferably shell script or sed.


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)
    )
  )



any help appreciated

Name
       ali - list mail aliases

Syntax
       ali [ -alias aliasfile ] [ -help ] [ -[no]list ] [ -[no]normalize ] [ -user useraddr ] [ -nouser ] [ aliases ...  ]

Description
       The  command  searches the specified mail alias files for each of the given aliases.  It creates a list of addresses for those aliases, and
       displays that list on the screen.

Options
       -alias aliasfile
		 Specifies the alias file to be consulted by You can specify more than one alias file, but each  aliasfile  must  be  preceded	by
		 -alias.  In addition to any alias files that you specify, consults the system alias file

		 You  can  set up an entry in your so that automatically consults an alias file.  To do this, add the Aliasfile entry to your pro-
		 file.	See for more information.

       -help	 Prints a list of the valid options to this command.

       -list
       -nolist	 Prints the addresses on separate lines.  If you do not specify the -list option,  the	addresses  are	separated  by  commas  and
		 printed on as few lines as possible.

       -normalize
       -nonormalize
		 Instructs  to try to track down the official hostname of the address.	This can be suppressed by using -nonormalize.  The default
		 is -nonormalize.

       -user useraddr
       -nouser	 Displays all the aliases that contain a specific name.  Instead of listing the addresses that each given alias expands to,  lists
		 the  aliases that expand to include each given address.  You must specify the complete user name that you have used in your alias
		 file.

       The defaults for this command are:

	      -alias /usr/lib/mh/MailAliases
	      -nolist
	      -nonormalize
	      -nouser

Examples
       The following example shows how the -user option can be used to list all the aliases containing the address Parker@Venus:
       % ali -user Parker@Venus
       Parker@Venus: Group, Reviewers, Badminton

Profile Components
       Path:	    Location of your Mail directory.
       Aliasfile:   Location of your personal alias file.

Files
       The user profile.

       The system alias file.

       The system password file.

       The system group file.
