The NodeIterator.nextNode() method sets the NodeIterator to next node in the document and returns the nextNode. The first call of the nextNode() returns the first node in the set.
This method returns null when there are no nodes left in the set.
Syntax:
node = nodeIterator.nextNode();
Parameters: This method takes no parameter.
Return Value: This method returns the next node in the set.
Example: In this example, we will create a node iterator and hence will iterate using the nextNode() method.
