[xml] push mode

[Luca Padovani <lpadovan CS UniBO IT>]

Hi,
I wonder if there is a clean way to use the "push method" with any kind of
document. The example in the home page shows how this can be done with a
regular file, but what if I have a URI?
I guess this has something to do with xmlParserInput and
xmlParserInputBuffer, but it is still not clear to me exactly how.
Any help?

        regards,
