hello I need modify aion game client server's name because it is korean

I am google for this problem
I am found some tool

use ("AIONencdec") to unpack aion (*.pak) file to a zip file and reverse pack it to *.pak
I found many xml and html file in unpacked zip file

I use "AIONdisasm" to decrypt xml to pure xml (readable)

I found server's name that I want to modify...in serverlist.xml file

then I modifed it
But now ... I stuck ...
I dont know how to encrypt pure xml (I modified) to previous format
because I want to repack it for aion client
the "AIONdisasm" does not say it can do that
if anyone know how to do that
please tell me
if have any tool can do that
