How does the namednodemap object work in XML?

The NamedNodeMap object represents an unordered list of nodes. 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.

Can a namednodemap object be auto updated?

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.

Is the namednodemap interface inherited from node objects?

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. This interface doesn’t inherit any property.

What’s the difference between a named node and a node map?

This is called a named node map, and is similar to a node list, except for some differences in methods and properties. An attribute list keeps itself up-to-date.

What is the public interface for namednodemap?

public interface NamedNodeMap Objects implementing the NamedNodeMapinterface are used to represent collections of nodes that can be accessed by name. Note that NamedNodeMapdoes not inherit from NodeList;

How is the namednodemapinterface used in nodelist?

Objects implementing the NamedNodeMapinterface are used to represent collections of nodes that can be accessed by name. Note that NamedNodeMapdoes not inherit from NodeList; NamedNodeMapsare not maintained in any particular order.

Can a namednodemapmay be accessed by an ordinal index?

Objects contained in an object implementing NamedNodeMapmay also be accessed by an ordinal index, but this is simply to allow convenient enumeration of the contents of a NamedNodeMap, and does not imply that the DOM specifies an order to these Nodes. NamedNodeMapobjects in the DOM are live.
