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.
