11.7. Accessing Attributes

Attributes in the DOM are accessed from an element node by means of the attributes variable. Attributes are stored in a structure known as a NamedNodeMap. A NamedNodeMap is like a NodeList except that nodes in a NamedNodeMap can be retrieved, based on the value of their nodeName attribute.

In the following example, a DOM tree is traversed, and attribute names and values printed out by traversal of a NamedNodeMap.
