public Interface NodeList

Known Direct Implementers: com.sun.org.apache.xml.internal.utils.UnImplNode, com.sun.org.apache.xpath.internal.NodeSet, com.sun.org.apache.xerces.internal.dom.DeepNodeListImpl, com.sun.org.apache.xerces.internal.dom.NodeImpl, com.sun.org.apache.xml.internal.dtm.ref.DTMNodeListBase

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.

Since: 1.4, DOM Level 2

Method Summary

Modifier and Type	Method and Description
public int	getLength() The number of nodes in the list.
public Node	Returns: The node at the `index`th position in the `NodeList`, or `null` if that is not a valid index. item(int Index into the collection. index) Returns the `index`th item in the collection.

Method Detail

getLength	back to summary
public int getLength() The number of nodes in the list. The range of valid child node indices is 0 to `length-1` inclusive.

item back to summary

item	back to summary
public Node item(int index) Returns the `index`th item in the collection. If `index` is greater than or equal to the number of nodes in the list, this returns `null`. Parameters index:int Index into the collection. Returns:Node The node at the `index`th position in the `NodeList`, or `null` if that is not a valid index.

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.

Parameters

index:int: Index into the collection.

Returns:Node

The node at the indexth position in the NodeList, or null if that is not a valid index.
