Interface NodeList

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 2 Core Specification.

Method Summary
`int` | `getLength()` The number of nodes in the list.
`Node` | `item(int index)` Returns the `index`th item in the collection.

Method Detail

### item

    public Node item(int index)

  Returns the `index`th item in the collection. If `index` is greater than or equal to the number of nodes in the list, this returns `null`.
  Parameters:
    `index` - Index into the collection.
  Returns:
    The node at the `index`th position in the `NodeList`, or `null` if that is not a valid index.

### getLength

    public int getLength()

  The number of nodes in the list. The range of valid child node indices is 0 to `length-1` inclusive.
