Reading and writing after a specific point in multilined text file

[reinhold]

Hey dday9 thanks for reply and looks like it should be working in theory but in my case all i get is an empty list.

Here's the actual text file i'm trying to get values from: http://pastebin.com/hpcz3USm

BTW, this list is static and lines will always stay the same.

In fact it looks like source code

I think it's a game ini file rather than code. Presumably modding is the ultimate aim.
