Re: [lxml] suppress namespace prefix in printouts

AFACIT the thing xmlfile() provides is a way to serialise a tag "as a
child" of another one, which solves the namespace thing. But from my PoV
it's unfortunate that it's used via a context manager - asynchronous code
styles differ, but I prefer to avoid keeping stack frames around.
Presumably I could drive the context manager myself, but... yuck.
It's pretty easy to map using a generator:

    def writer(out_stream, terminator="DONE"):
        with xmlfile(out_stream) as xf:
             with xf.element('root'):
                  try:
                      while True:
                          el = (yield)
                          xf.write(el)
                  except GeneratorExit:
                      pass

    w = writer(stream)
    next(w)

And then, whenever you have something to write, you say

    w.send(el)

And when done:

    w.close()

Something along those lines. Completely untested, but if someone gets this
to work nicely, I'd take doc patches. :)
