Structure of language file

Hello,

i have to translate those objects in a database that have no
polish ML Caption. I did not found a tool wich shows the objects
that havent a special language such as polish and offers functionality to translate it.

So, i wanna write my own program that can handle the transaltionsfile that can be created by tools->tramslate->export. But first of all i must understand the structure in this file.

Do anyone know the structure from the translation file?

Thx a lot
