通过XPathDocument、XmlDocument读取Xml文件中的节点值

XPathDocument doc = new XPathDocument(Server.MapPath(@"~/XML/Guitars.xml"));//包装XML文档
XPathNavigator nav = doc.CreateNavigator();//创建XPathNavigator
XPathNodeIterator iterator = nav.Select("/Guitars/Guitar");//查询，返回值为节点集
while (iterator.MoveNext())//下个节点
{
XPathNodeIterator it = iterator.Current.Select("Make");
it.MoveNext();
string make = it.Current.Value;//当前节点
it = iterator.Current.Select("Model");
it.MoveNext();
string model = it.Current.Value;
Response.Write(make + "    " + model + "<br>");
}

XmlDocument xmldoc = new XmlDocument();
xmldoc.Load(Server.MapPath(@"~/XML/Guitars.xml"));
XmlNodeList nodes = xmldoc.GetElementsByTagName("Guitar");
foreach (XmlNode node in nodes)
{
Response.Write(string.Format("{0}    {1}", node["Make"].InnerText, node["Model"].InnerText) + "<br>");
}
