How you would like to do that?
Shell scripts? Probably if you can use Perl will have better result and the program will be easier for programming.

crude example, will modify and create .bak file

Code:

 perl -pi.bak -e 's|(<server ip=).*|$1"255.255.255.255" port="5555"/>|'

hello wmh830621
you can try this concept of mine. just try to improve the code. i also haven't tested it yet cause i don't have any access to a terminal or console right now.

Code:

#!/bin/bash

# you can use read or VAR="$1" to setup these variables
SERVER_IP=
SERVER_PORT=
LANGUAGE_URL=
PROJECT_NAME=
OUTPUTFIL=

{
    echo "<?xml version=\"1.0\" encoding=\"Shift-JIS\"?>"
    echo "<flash_cfg>"
    echo "<server ip=\"${SERVER_IP}\" port=\"${SERVER_PORT}\"/>"
    echo "<language_url>${LANGUAGE_URL}</language_url>"
    echo "<project_name>${PROJECT_NAME}</project_name>"
    echo "</flash_cfg>"
} > ${OUTPUTFIL}

hello again wmh830621. i got your message from mail and i thought that i should frankly tell you that it will just take too long to discuss the code.

rather i'm suggesting that you read:
bash beginner's guide: http://www.tldp.org/LDP/Bash-Beginne...tml/index.html
and then
advanced bash scripting howto http://www.tldp.org/LDP/abs/html/

please try them. they're just easy to understand. also take note more on variables, quoting and output redirection.

--------------------
ok i'll explain some

these are the variables

Code:

SERVER_IP=
SERVER_PORT=
LANGUAGE_URL=
PROJECT_NAME=
OUTPUTFIL=

the next commands are enclosed in braces to redirect their output to the file

Code:

{ 
   commands
} > FILE

so

Code:

{
    echo "<?xml version=\"1.0\" encoding=\"Shift-JIS\"?>"
    echo "<flash_cfg>"
    echo "<server ip=\"${SERVER_IP}\" port=\"${SERVER_PORT}\"/>"
    echo "<language_url>${LANGUAGE_URL}</language_url>"
    echo "<project_name>${PROJECT_NAME}</project_name>"
    echo "</flash_cfg>"
} > ${OUTPUTFIL}
