This article needs a technical review. How you can help.

The NodeIterator.nextNode() method returns the next node in the set represented by the NodeIterator and advances the position of the iterator within the set.  The first call to nextNode() returns the first node in the set.

This method returns null when there are no nodes left in the set.

In old browsers, as specified in old versions of the specifications, the method may throws the INVALID_STATE_ERR DOMException if this method is called after the NodeIterator.detach()method. Recent browsers never throw.


node = nodeIterator.nextNode();


var nodeIterator = document.createNodeIterator(
    { acceptNode: function(node) { return NodeFilter.FILTER_ACCEPT; } },
    false // this optional argument is not used any more
currentNode = nodeIterator.nextNode(); // returns the next node
