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.

[!NOTE] Although called NamedNodeMap, this interface doesn’t deal with Node objects but with Attr objects, which are a specialized class of Node objects.
