Try this code. For now I've just added the new 'MF' node after the existing one: Imports System Imports System.Xml Module Program Sub Main() Dim doc As New XmlDocument doc.Load(oca.xml) ' say Dim list As XmlNodeList = doc.GetElementsByTagName(CardCode) Dim csNode As XmlNode = Nothing For Each ccNode AS XmlNode in list Dim value As String = ccNode.InnerText If value = CC6 Then csNode = ccNode.ParentNode Dim vNode As XmlNode = csNode.SelectSingleNode(Version) If vNode IsNot Nothing Then value = vNode.InnerText If value = 1.0 Then Exit For End If End If End If Next If csNode IsNot Nothing Then Dim mfNode As XmlElement = doc.CreateElement(MF) 'add some attributes with arbitrary values mfNode.SetAttribute(BS 3821) mfNode.SetAttribute(FID 3F01) mfNode.SetAttribute(AC 0001) mfNode.SetAttribute(KN 0001) csNode.AppendChild(mfNode) Console.WriteLine(Saving amended file) doc.Save (oca2.xml) ' use same filename if want to overwrite End If End Sub End Module
