XML DOM - The NamedNodeMap Object

prev next

The NamedNodeMap object represents an unordered list of nodes.


The NamedNodeMap object

The nodes in the NamedNodeMap can be accessed through their name.

The NamedNodeMap keeps itself up-to-date. If an element is deleted or added, in the node list or the XML document, the list is automatically updated.

Note: In a named node map, the nodes are not returned in any particular order.

IE: Internet Explorer, F: Firefox, O: Opera, W3C: World Wide Web Consortium (Internet Standard)
