Anyways, the regex is about a couple of pages long and it works just peachy.
There's just one thing I'd like to do to make it more elegant.
I need to compile the regex with MULTILINE and DOTALL. But there are a few
sections where I wish it was *not* compiled with DOTALL. For those cases, I
use (something like)
[^\n]*
instead of
.*
I see that I can use the (?MS) construct but I also see that it applies
globally and not to the subgroup that I'm using it in.
* Is there a way to make it apply locally to a subgroup?
It with the re module.
* If not, is there another way?
The DOTALL . could be replaced with, say, [\d\D].
* Also, is this an incredible stroke of genius that I came up with this idea
of applying flags to a subgroup, or have others thought of this too and found
out that it's not really a good idea?
Many other regex implementations do support scoped flags, including the
one here:
http://pypi.python.org/pypi/regex
which is designed to be backwards-compatible with the re module.
