			// bytes from StreamInput after this event, as the '>' character will end up
			// in the unprocessed chunk.  To work around this, we need to advance StreamInput's
			// internal byte processing, but not the xml character data.  This way, the '>'
			// will get processed and will no longer be in the unprocessed return, but
			// QXmlSimpleReader can still read it.  To do this, we call StreamInput::readNext
