It's possible to have more than one @doc/@c (or simply @/@c) directive
pairs.
It's a moot point in python programming because docstrings are considered
better style.
Keeping things simple, I need to figure out how to select everything in a

Exactly as stated, this might indeed be "full of hairballs". There are at
leas two preliminary questions that may help you make this simpler.
1. Whenever dealing with sections (<< whatever >> ) and their expansions,
you should think first of top-level code in leoAtFile.py that "pretends" to
write the file, but instead writes the file to a string:
def write(self, root,
kind='@unknown', # Should not happen.
nosentinels=False,
perfectImportFlag=False,
scriptWrite=False,
thinFile=False,
toString=False,
):
This method really should have a better docstring. In particular, the
docstring should mention that at.stringOutput contains the resulting string
when toString is True.
The following is tested code (in an @button node):
at = c.atFileCommands
at.write(
p,
kind='@file',
nosentinels=True,
toString=True,
)
print(at.stringOutput)
2. I wouldn't try to *replace *the parts of an outline unless there is
absolutely no other way. Instead, I would write the result of point 1
somewhere, say in an @toggle-name tree:
@toggle-name
@toggle-@file-a
@toggle-@clean-b
...
Something like this should save you from having to touch actual code.
HTH.
