item Method (IXMLDOMNodeList)
Allows random access to individual nodes within the collection.
Script Syntax
var objXMLDOMNode = oXMLDOMNodeList.item(index);
Parameters
- index
- A long integer. An index of the item within the collection. The first item is zero.
Return Value
An object. Returns IXMLDOMNode
. Returns Null if the index is out of range.
Example
The following script example creates an IXMLDOMNodeList
object with the document's getElementsByTagName
method. It then iterates through the collection, displaying the text value of each item in the list.
var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.5.0"); var objNodeList; xmlDoc.async = false; xmlDoc.load("books.xml"); if (xmlDoc.parseError.errorCode <> 0) { var myErr = xmlDoc.parseError; alert("You have error " + myErr.reason); } else { objNodeList = xmlDoc.getElementsByTagName("author"); for (var i=0; i<objNodeList.length; i++) { alert(objNodeList.item(i).text); } }
Visual Basic Syntax
Set objXMLDOMNode = oXMLDOMNodeList.item(index)
Parameters
- index
- A long integer. An index of the item within the collection. The first item is zero.
Return Value
An object. Returns IXMLDOMNode
. Returns Null if the index is out of range.
Example

object with the document's getElementsByTagName
method. It then iterates through the collection, displaying the text value of each item in the list.
Dim xmlDoc As New Msxml2.DOMDocument50 Dim objNodeList As IXMLDOMNodeList xmlDoc.async = False xmlDoc.Load ("books.xml") If (xmlDoc.parseError.errorCode <> 0) Then Dim myErr Set myErr = xmlDoc.parseError MsgBox("You have error " & myErr.reason) Else Set objNodeList = xmlDoc.getElementsByTagName("author") For i = 0 To (objNodeList.length - 1) MsgBox objNodeList.Item(i).Text Next End If
C/C++ Syntax

. Returns Null if the index is out of range.
