      Description copied from interface: SequenceIterator
      Get another SequenceIterator that iterates over the same items as the original, but which is repositioned at the start of the sequence.

      This method allows access to all the items in the sequence without disturbing the current position of the iterator. Internally, its main use is in evaluating the last() function.

      This method does not change the state of the iterator.

      Specified by:
      getAnother in interface SequenceIterator
      Returns:
      a SequenceIterator that iterates over the same items, positioned before the first item
      Throws:
      XPathException - if any error occurs
