ISTM you could simplify it enormously by just looking for the opening string: shared_network = "My-Network-FECO" network = filebody.split("\nshared-network "+shared_network+" {",1)[1].split("\n}\n")[0] Assuming your file is always correctly indented, and assuming you don't have any other instances of that header string, you should be fine.
