Examples of org.apache.xml.dtm.DTMIterator.nextNode()

org.apache.xml.dtm.DTMIterator.nextNode()
Returns the next node in the set and advances the position of the iterator in the set. After a DTMIterator has setRoot called, the first call to nextNode() returns that root or (if it is rejected by the filters) the first node within its subtree which is not filtered out. @return The next node handle in the set being iterated over, orDTM.NULL if there are no more members in that set.

      // the number function is true. 
      DTMIterator list1 = iterRaw();
      double num2 = obj2.num();
      int node;


      while (DTM.NULL != (node = list1.nextNode()))
      {
        double num1 = getNumberFromNode(node);
