Hi all,
I'm working on a Python _3_ project that will be used to parse ISC
DHCPD configuration files for statistics and alarming purposes (IP
address pools, etc). Anyway, I'm hung up on this one section and was
hoping someone could provide me with some insight.
My script first reads the DHCPD configuration file into memory -
variable "filebody". It then utilizes the re module to find the
configuration details for the wanted "shared network".
Hi Jason,
If you actually look at the syntax of what you are parsing, it is very
simple.
My recommendation would be to write a recursive decent parser for your
files.
That way will be easier to write, much easier to modify and almost
certainly faster that a RE solution - and it can easily give you all the
information in the file thus future proofing it.
