  This might help:

  Imports System.Xml

  Module Module1

  Sub Main()

  Dim xmlDoc As New XmlDocument

  Dim xmlNode As XmlNode

  Dim xpathExpr As String

  xmlDoc.LoadXml("<?xml version='1.0'?><root><person age='21'><name>Martin Fowler</name></person><person age='51'><name>Martin Fowler</name></person><person><name>Kent Beck</name></person><person><name>Dave Astels</name></person></root>")

  ' Find a node

  xpathExpr = "/root/person[@age='51' and name='Martin Fowler']"

  xmlNode = xmlDoc.SelectSingleNode(xpathExpr)

  ' Perform an update

  xmlNode.InnerText = "Fred Brooks"

  ' Check this node

  Console.WriteLine(xmlNode.OuterXml)

  Console.ReadLine()

  ' Check the rest of the document

  Console.WriteLine(xmlDoc.OuterXml)

  Console.ReadLine()

  ' Save updated document

  xmlDoc.Save("updated.xml")

  End Sub

  End Module
