Just so's you know, my mention of C++ and XSL actually means that's all I use
- I think.  (C# is on the horizon, and I once wrote something in Java, though
that was because I couldn't find a MIB reading library for C++, else I'd have
done that)
I don't use Python at all, so that really isn't an option.

So - if it's XML it'll be XSL to process it.

Maybe do it in Python with the "lxml" module?

The files are in similar folders, called

acq_(\d{4}) and out_(\d{4}). There is identical
