 def GetRemainder(self):
 """Method to get the remainder of the buffered XML. this method stops the parser, set its state to End Of File and return the input stream with what is left that the parser did not use. The implementation is not good, the parser certainly procgressed past what's left in reader->input, and there is an allocation problem. Best would be to rewrite it differently. """
