class HappeningsRenum(renum):
    ADMITTED = r"@@(?P<nation>[^@]+)@@ was admitted to the World Assembly\."
    MOVED = r"@@(?P<nation>[^@]+)@@ relocated from %%(?P<from>[^%]+)%% to %%(?P<to>[^%]+)%%\."
    ENDORSED = r"@@(?P<endorser>[^@]+)@@ endorsed @@(?P<endorsee>[^@]+)@@\."
    WITHDREW_ENDORSEMENT = r"@@(?P<endorser>[^@]+)@@ withdrew its endorsement from @@(?P<endorsee>[^@]+)@@\."


def main():
    root = ET.parse("happenings.xml")
    for element in root.iterfind("HAPPENINGS/EVENT/TEXT"):
        event = HappeningsRenum.fullmatch(element.text)
        if event is HappeningsRenum.ADMITTED:
            print("Welcome to the WA, %s!" % event.last_match.group("nation"))
        elif (
            event is HappeningsRenum.MOVED
            and event.last_match.group("to") == "the_rejected_realms"
        ):
            print("Welcome to TRR, %s!" % event.last_match.group("nation"))
        elif (
            event is HappeningsRenum.ENDORSED
            and event.last_match.group("endorsee") == "zephyrkul"
        ):
            print(
                "Thanks for the endorsement, %s!" % event.last_match.group("endorser")
            )
        elif (
