Class org.w3c.dom.traversal.NodeIterator

Examples of org.w3c.dom.traversal.NodeIterator.nextNode()

org.w3c.dom.traversal.NodeIterator.nextNode()
Returns the next node in the set and advances the position of the iterator in the set. After a NodeIterator is created, the first call to nextNode() returns the first node in the set. @return The next Node in the set being iterated over, ornull if there are no more members in that set. @exception DOMException INVALID_STATE_ERR: Raised if this method is called after the detach method was invoked.
