[Twisted-Python] connecting with a FlashXML socket

[Patrick Lauber]

i use a \x00 as a terminator....
this script below has an other class changhandler that looks if there is 
a new file in directory and sends that file (xml) to all connected 
clients... it's used for a web radio to push the meta infos to the clients.
have fun

from twisted.internet.protocol import Factory, Protocol

class Radio(Protocol):
   
    def connectionMade(self):
        self.factory.clients.append(self)
        self.transport.write(self.factory.msg)
        self.ip=self.transport.getHost().host
        print self.ip+' connected'
    def dataReceived(self, data):
        print data
        try:
            doc=parseString(data[0:-1])
            if doc.nodeName == 'connect':
                if doc.attributes.has_key('service'):
                    self.service=doc.attributes['service']._value
                    print "new service"+self.sevice
                else:
                    print "connect was malformatted"
            else:
                pass
        except:
           print "parsing error"
