Contains the next sibling of the node in the parent's child list.
var objXMLDOMNode = oXMLDOMNode.nextSibling;
The following script example creates an IXMLDOMNode object and sets it to the next sibling of the current node.
var xmlDoc = new ActiveXObject5.0("Msxml2.DOMDocument.5.0");
var currNode;
var nextNode;
xmlDoc.async = false;
xmlDoc.load("books.xml");
if (xmlDoc.parseError.errorCode <> 0) {
   var myErr = xmlDoc.parseError;
   alert("You have error " + myErr.reason);
} else {
   currNode = xmlDoc.documentElement.childNodes.item(0);
   nextNode = currNode.nextSibling;
   alert(nextNode.xml);
}
Set objXMLDOMNode = oXMLDOMNode.nextSibling
The following Microsoft® Visual Basic® example creates an IXMLDOMNode object and sets it to the next sibling of the current node.
Dim xmlDoc As New Msxml2.DOMDocument50
Dim currNode As IXMLDOMNode
Dim nextNode As IXMLDOMNode
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 currNode = xmlDoc.documentElement.childNodes.Item(0)
   Set nextNode = currNode.nextSibling
   MsgBox nextNode.xml
End If
HRESULT get_nextSibling(
    IXMLDOMNode **nextSibling);
nextSibling parameter is Null.The property is read-only. It returns the right sibling of this node.
This value depends on the value of the nodeType property.
| NODE_ATTRIBUTE
 NODE_DOCUMENT NODE_DOCUMENT_FRAGMENT  | 
Always returns Null; these node types do not appear as children of any other nodes. | 
| NODE_CDATA_SECTION
 NODE_COMMENT NODE_DOCUMENT_TYPE NODE_ELEMENT NODE_ENTITY NODE_ENTITY_REFERENCE NODE_NOTATION NODE_PROCESSING_INSTRUCTION NODE_TEXT  | 
Returns the node immediately following this node in the list of children of this node's parent. If no such node exists, returns Null. |
