maybe you'd rather replace:
splitter = re.compile(r'(?m)^(?P<data>.*?(".*?".*?)*)(?:#.*?)?$')
by
from reO import *
quote = characters('"') # defining the characters used as string sep
sharp= string('#') # defining the sharp symbol
data = ALL + repeat( group( quote + ALL + quote + ALL ) ) # ALL
( "ALL" ALL)*
comment = group(sharp+ALL+END_LINE) # the comment itself
xp = flag(MULTILINE=True) + START_LINE + group( data, name="data") +
if_exists(comment)
splitter = xp.compile()
