getItem
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
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.
