Interface org.w3c.dom.html.HTMLCollection

public interface HTMLCollection
An HTMLCollection 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.


Method Index

 o getLength()
This attribute specifies the length or size of the list.
 o item(int)
This method retrieves a node specified by ordinal index.
 o namedItem(String)
This method retrieves a Node using a name.

Methods

 o getLength
 public abstract int getLength()
This attribute specifies the length or size of the list.

 o item
 public abstract 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.
 o namedItem
 public abstract Node namedItem(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.
