我想把元素<author>里面的文本节点替换掉。但是写了个RepalceElement（）的 方法显示没有替换成功。请各位多多指教。
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
XmlDocument document = new XmlDocument();
AddElement(document);
InsertElement(document);
RepalceElement(document);
}
private void AddElement(XmlDocument document)
{
XmlElement bookselement = document.CreateElement("books");
XmlElement bkelement = document.CreateElement("book");
XmlElement nameelement = document.CreateElement("name");
nameelement.SetAttribute("id", "1");
nameelement.InnerText = "C#";
bkelement.AppendChild(nameelement);
XmlElement authorelement = document.CreateElement("author");
authorelement.InnerText = "Microsoft";
bkelement.AppendChild(authorelement);
XmlElement priceelement = document.CreateElement("price");
priceelement.InnerText = "100";
bkelement.AppendChild(priceelement);
bookselement.AppendChild(bkelement);
document.AppendChild(bookselement);
document.Save(Server.MapPath("books.xml"));
}
private void InsertElement(XmlDocument document)
{
document.Load(Server.MapPath("books.xml"));
XmlNode node = document.SelectSingleNode("books");
XmlElement bkelement = document.CreateElement("book");
XmlElement nameelement = document.CreateElement("name");
nameelement.SetAttribute("id", "2");
nameelement.InnerText = "Java";
bkelement.AppendChild(nameelement);
XmlElement authorelement = document.CreateElement("author");
authorelement.InnerText = "SUN";
bkelement.AppendChild(authorelement);
XmlElement priceelement = document.CreateElement("price");
priceelement.InnerText = "130";
bkelement.AppendChild(priceelement);
node.AppendChild(bkelement);
//Response.Write("node 的 name= " + node.Name);
//Response.Write("<br>");
//Response.Write("priceelement 的 name= " + priceelement.Name);
document.Save(Server.MapPath("books.xml"));
}
private void RepalceElement(XmlDocument document)
{
document.Load(Server.MapPath("books.xml"));
XmlNodeList nodelist = document.SelectSingleNode("books").ChildNodes;
XmlElement element;
foreach (XmlNode node in nodelist)
{
element = (XmlElement)node;
if (element.Name == "author")
{
element.InnerText = "波兰"; //这里就没有替换成功。
break;
}
break;
}
document.Save(Server.MapPath("books.xml"));
}
}
