The NamedNodeMap object represents a sequenceless table of nodes.
This section describes the properties and methods of the NamedNodeMap object.
Nodes in NamedNodeMap can be accessed by their names.
NamedNodeMap will update itself. If you delete or add an element to a node list or XML document, the list updates automatically.
Note: In a named node diagram, nodes are not returned in any particular order.
