public interface NodeList
The
NodeList interface provides the abstraction of an ordered
collection of nodes, without defining or constraining how this collection
is implemented.
NodeList objects in the DOM are live.
The items in the
NodeList are accessible via an integral
index, starting from 0.
See also the
Document Object Model (DOM) Level 3 Core Specification.
int | getLength()- The number of nodes in the list.
|
Node | item(int index)- Returns the
indexth item in the collection.
|
getLength
public int getLength()
The number of nodes in the list. The range of valid child node indices
is 0 to length-1 inclusive.
item
public Node item(int index)
Returns the indexth item in the collection. If
index is greater than or equal to the number of nodes in
the list, this returns null.
index - Index into the collection.
- The node at the
indexth position in the
NodeList, or null if that is not a valid
index.
