I am not familiar enough with PB, but I assume that PB cannot serialize objects of unknown classes without any help. In general, serialization of XML is way more expensive than parsing, but I'd be very curious about when this would actually become a problem. > I'm considering reducing the Element instances to dicts but I may leave > out details I may need in the future. Except for parent, the instance variables mentioned in the docstring of Element is all you need to remember. Note that this also requires walking the DOM tree for the element you want to send over, and then build up the tree on the other side. It might be just as expensive as using an XML stream. I've been thinking about building a (streaming) parser that would mostly lex the incoming XML stream and only extract as much as needed for routing, leaving the XML Stanza's payload as an unparsed string that can be sent along further. ralphm _______________________________________________ Twisted-Python mailing list Twisted-Python@twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python
