NamedNodeMap

The NamedNodeMap interface represents a collection of Attr objects. Objects inside a NamedNodeMap are not in any particular order, unlike NodeList, although they may be accessed by an index as in an array.

A NamedNodeMap object is live and will thus be auto-updated if changes are made to its contents internally or elsewhere.

Although called NamedNodeMap, this interface doesn't deal with Node objects but with Attr objects, which were originally a specialized class of Node, and still are in some implementations.

Properties

This interface doesn't inherit any property.

NamedNodeMap.length Read only: Returns the amount of objects in the map.

NamedNodeMap.getNamedItem(): Returns a Attr, corresponding to the given name.
NamedNodeMap.setNamedItem(): Replaces, or adds, the Attr identified in the map by the given name.
NamedNodeMap.removeNamedItem(): Removes the Attr identified by the given map.
NamedNodeMap.item(): Returns the Attr at the given index, or null if the index is higher or equal to the number of nodes.
NamedNodeMap.getNamedItemNS(): Returns a Attr identified by a namespace and related local name.
NamedNodeMap.setNamedItemNS(): Replaces, or adds, the Attr identified in the map by the given namespace and related local name.
NamedNodeMap.removeNamedItemNS(): Removes the Attr identified by the given namespace and related local name.
