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.

int	getLength() This attribute specifies the length or size of the list.
T	getNamedItem(java.lang.String name) This method retrieves a Node using a name.

Method Detail

getItem

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.

getLength

public final int getLength()

This attribute specifies the length or size of the list.

getNamedItem

public final T getNamedItem(java.lang.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.
