I'd probably reach for ANTLR to write a quick parser since working with such a stickler is likely to require more code formatting changes in the future. As an aside, the stuff I used sed/awk for in the past have pretty much been replaced by Python for me. These days it's pretty rare to not have a default Python install on any Unixy box one spins up and in the rare cases I use Windows I tend to install Anaconda so it's also slightly more cross-platform for my use cases.
