sed - How to insert line before the first blank line following a token
Hello.

I have a config file (/etc/my_config_file) which may content :

Code:
#
# port for HTTP (descriptions, SOAP, media transfer) traffic
port=8200

# network interfaces to serve, comma delimited
network_interface=eth0

# set this to the directory you want scanned.
# * if have multiple directories, you can have multiple media_dir= lines
# * if you want to restrict a media_dir to a specific content type, you
#   can prepend the type, followed by a comma, to the directory:
#   + "A" for audio  (eg. media_dir=A,/home/jmaggard/Music)
#   + "V" for video  (eg. media_dir=V,/home/jmaggard/Videos)
#   + "P" for images (eg. media_dir=P,/home/jmaggard/Pictures)
#media_dir=V,/srv/media/film
#media_dir=A,/srv/media/musique
#media_dir=P,/srv/media/photo
#media_dir = /home/some_user/my_personal_old_data

# set this if you want to customize the name that shows up on your clients
friendly_name=SJL DLNA Server MY_SERVER OPENSUSE 13.1

I have a variable which contains the token to search :
Code:
MY_TOKEN="media_dir"

I have a variable which contains the file to search in
Code:
MY_FILE="/etc/my_config_file"

I have a variable which contains the value for the searched token
Code:
MY_PARAMETER_VALUE="media_dir = /srv/media/my_personal_new_data"

I want to insert $MY_PARAMETER_VALUE, before the blank line and after the line : #media_dir = /home/some_user/my_personal_old_data
and the search token is $MY_TOKEN using some function like :

Code:
my_insert  $MY_TOKEN  $MY_PARAMETER_VALUE $MY_FILE

Any help is welcome
