no need to go global, use a class instead, like:
[[not tested and I know nothing about xml]]


class Record:
    def __init__(self, **kws):
        self.__dict__.update(kws)

class Data:
    def __init__(self):
        self.data = []

    def s_el(self, name, attrs):
        self.data.append(Record(type="s_el", name=name, attrs=attrs))

    def e_el(self, name):
        self.data.append(Record(type="e_el", name=name))

    def c_data(self, data):
        self.data.append(Record(type="c_el", data=data))

    def printit(self):
        for r in self.data:
            if r.type == "s_el":
	        print r.name, "(attributes -->", r.attrs, ")"
            elif r.type == "e_el":
	        print "   (attribute", r.name, "ends)"
            elif r.type == "c_el":
	        print "    `--->", r.data


data = Data()

prs = xml.parsers.expat.ParserCreate()
prs.StartElementHandler = data.s_el
prs.EndElementHandler = data.e_el
prs.CharacterDataHandler = data.c_data
prs.returns_unicode = 0
prs.Parse(xmlpp)

data.printit()
