how do I keep track? The first result value is outside a filters
section and the rest are. Do you mean something like:

    def startElement(self, name, attrs):
        if name == 'event':
            self.eventTime = attrs.get('eventTimestamp',"")
            self.eventUniqueId = attrs.get('uniqueId', "")
        if name == 'result':
                self.resultValue = attrs.get('value',"")
        if name == filters:
            if name == 'result':
                self.resultValueF = attrs.get('value',"")
        return
