Class Overview

An ElementCollection is a list of nodes. An individual node may 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 meaning that they are automatically updated when the underlying document is changed.

Public Methods

public final T getItem (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 element at the corresponding position upon success. A value of null is returned if the index is out of range.

public final int getLength ()

This attribute specifies the length or size of the list.

public final T getNamedItem (String name)

This method retrieves a Node using a name. With [HTML 4.01] documents, 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. With [XHTML 1.0] documents, this method only searches for Nodes with a matching id attribute. This method is case insensitive in HTML documents and case sensitive in XHTML documents.

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