查询的：
XmlNode d = xmlDoc.FirstChild.SelectSingleNode("Customer[@Name='yangdong']"); 查询XmlDoc文档的第一个节点下所有Name为yangdong的Customer节点。

读:
Dim xmlfile As String = filepath
Dim xmlD As New Xml.XmlDocument
xmlD.Load(xmlfile )
Dim xmldatabase As Xml.XmlNode
Dim xmlDBList As Xml.XmlNodeList = xmlD.SelectNodes("//AesTools//DataBase")

For Each xmldatabase In xmlDBList
databasename = xmldatabase.InnerText
Next

写:

Dim xmlD As New Xml.XmlDocument
Dim xmlE As Xml.XmlNode = xmlD.CreateNode(Xml.XmlNodeType.Element, "DataBase", "")
Dim xmlTmpNode As Xml.XmlNode = xmlD.SelectSingleNode("//AesTools")

xmlD.LoadXml("<AesTools></AesTools>")
xmlE = xmlD.CreateNode(Xml.XmlNodeType.Element, "DataBase", "")
xmlE.InnerText = "DOMDomain"
xmlTmpNode = xmlD.SelectSingleNode("//AesTools")
xmlTmpNode.AppendChild(xmlE)
xmlD.Save("c:\DataBase.XML")
