First, XML-RPC is not the only mechanism using XML over a network connection. Second, you don't want to do this if you're dealing with several 100 MB of data just because you want to figure out the encoding. That's my original claim/question: what SPECIFIC application do you have in mind that transfers XML over a network and where you would want to have such a stream codec? XML-based web services used for business integration, e.g. based on ebXML. A common use case from our everyday consulting business is e.g. passing market and trading data to portfolio pricing web services. I still don't see the need for this feature from this example. First, in ebXML messaging, the message are typically not large (i.e. much smaller than 100 MB). Furthermore, the typical processing of such a message would be to pass it directly to the XML parser, no need for the functionality under discussion.

I don't see the point in continuing this discussion. If you think you know better, that's fine. Just please don't generalize this to everyone else working with Python and XML.

Right. However, I' will remain opposed to adding this to the standard library until I see why one would absolutely need to have that. Not every piece of code that is useful in some application should be added to the standard library. Agreed, but the application space of web services is large enough to warrant this. If that was the case, wouldn't the existing Python web service libraries already include such a functionality?

No.

To finalize this:

We have a -1 from Martin and a +1 from Walter, Guido and myself. Pretty clear vote if you ask me. I'd say we end the discussion here and move on.
