var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.5.0"); var currNode; var prevNode; 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(1); prevNode = currNode.previousSibling; alert(prevNode.xml); }
Visual Basic Syntax
Set objXMLDOMNode = oXMLDOMNode.previousSibling
Example
The following Microsoft® Visual Basic® example creates an IXMLDOMNode
object and sets it to the previous sibling of the current node.
Dim xmlDoc As New Msxml2.DOMDocument50 Dim currNode As IXMLDOMNode Dim prevNode 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(1) Set prevNode = currNode.previousSibling MsgBox prevNode.xml End If
