Hi - please could you let me know of a good resource for understanding how to parse company information using the python xbrl library?
I can parse data using:
from xbrl import XBRLParser
xbrl_parser = XBRLParser()
xbrl = xbrl_parser.parse(open("%s/%s" % (fold,f)))
gaap_obj = xbrl_parser.parseGAAP(xbrl,
but the returned GAAP object contains zeros for all the accounting entries.
Is there a better library or different parser I should be using?
