Method Details

getLength

public int getLength()
This attribute specifies the length or size of the list.
Specified by:
getLength in interface HTMLCollection

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).
Specified by:
item in interface HTMLCollection
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.

namedItem

public Node namedItem(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.
Specified by:
namedItem in interface HTMLCollection
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.
