    public interface HTMLCollection

An `HTMLCollection` is a list of nodes. An individual nodemay be accessed by either ordinal index or the node's`name` or `id` attributes. Note:Collections in the HTML DOM are assumed to be live meaningthat they are automatically updated when the underlying document ischanged.

### Method Summary

All Methods Instance Methods Abstract Methods
`int` `getLength()` This attribute specifies the length or size of the list.
`Node` `item(int index)` This method retrieves a node specified by ordinal index.
`Node` `namedItem(java.lang.String name)` This method retrieves a `Node` using a name.

### Method Detail

#### getLength

    int getLength()

This attribute specifies the length or size of the list.

#### item

    Node item(int index)

This method retrieves a node specified by ordinal index. Nodes are numbered in tree order (depth-first traversal order).

Parameters:
  `index` - The index of the node to be fetched. The index origin is 0.
Returns:
  The `Node` at the corresponding position upon success. A value of `null` is returned if the index is out of range.

#### namedItem

    Node namedItem(java.lang.String name)

This method retrieves a `Node` using a name. It first searches for a `Node` with a matching `id` attribute. If it doesn't find one, it then searches for a `Node` with a matching `name` attribute, but only on those elements that are allowed a name attribute.

Parameters:
  `name` - The name of the `Node` to be fetched.
Returns:
  The `Node` with a `name` or `id` attribute whose value corresponds to the specified string. Upon failure (e.g., no node with this name exists), returns `null`.
