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.
This method retrieves a node specified by ordinal index. Nodes are numbered
in tree order (depth-first traversal order).
index - The index of the node to be fetched. The index origin is 0.
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(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.
name - The name of the Node to be fetched.
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.
