public interface NodeList
The
NodeList
interface provides the abstraction of an ordered
collection of nodes, without defining or constraining how this collection
is implemented.
NodeList
objects in the DOM are live.
The items in the
NodeList
are accessible via an integral
index, starting from 0.
See also the
Document Object Model (DOM) Level 3 Core Specification.
int | getLength() - The number of nodes in the list.

Node | item(int index) - Returns the
index th item in the collection.

index
is greater than or equal to the number of nodes in
