Thanks for the reply Lasse.
I should have explained it bit clearly in my initial post. Actually I was looking for various possible ways to acheive this. Using
Java is one way, but is there some other way?
I need this tool to be as generic as possible. It should be possible for me to modify the variable file and / or the template file with out changing the code.
I could very well use your logic and create this utility, but I would like to check if there are any tools available to acheive the same.
