Interface 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.
See also the
Document Object Model (DOM) Level 1 Specification (Second Edition).
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(String name)- This method retrieves a
Node using a name.

getLength
public int getLength()
This attribute specifies the length or size of the list.
item
public Node item(int index)
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
Node at the corresponding position upon
success. A value of null is returned if the index is
out of range.
namedItem
public 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.
name - The name of the Node to be fetched.
- 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.
