asp.net 生成网站地图 sitemap.xml
此处为Demo，借鉴别人的生成 xml
//创建xml文件方法一
protected void btn1_OnClick(object sender, EventArgs e)
{
XmlText xmltext;
XmlDocument xmldoc = new XmlDocument();
//加入XML的声明段落
XmlNode xmlnode = xmldoc.CreateXmlDeclaration("1.0", "gb2312", null);
xmldoc.AppendChild(xmlnode);
//加入一个根元素
XmlElement xmlelem = xmldoc.CreateElement("", "bookstore", "");
xmltext = xmldoc.CreateTextNode("");
xmlelem.AppendChild(xmltext);
xmldoc.AppendChild(xmlelem);
//加入一个子元素
XmlElement xmlelem1 = xmldoc.CreateElement("", "book", "");
xmltext = xmldoc.CreateTextNode("");
xmlelem1.AppendChild(xmltext);
//为子元素"book"增加两个属性
xmlelem1.SetAttribute("genre", "", "fantasy");
xmlelem1.SetAttribute("ISBN", "2-3631-4");
xmldoc.ChildNodes.Item(1).AppendChild(xmlelem1);
//创建三个子元素的子元素
XmlElement xmlelem2 = xmldoc.CreateElement("", "title", "");
xmltext = xmldoc.CreateTextNode("Oberon's Legacy");
xmlelem2.AppendChild(xmltext);
xmldoc.ChildNodes.Item(1).AppendChild(xmlelem1).AppendChild(xmlelem2);
XmlElement xmlelem3 = xmldoc.CreateElement("", "author", "");
xmltext = xmldoc.CreateTextNode("Corets, Eva");
xmlelem3.AppendChild(xmltext);
xmldoc.ChildNodes.Item(1).AppendChild(xmlelem1).AppendChild(xmlelem3);
XmlElement xmlelem4 = xmldoc.CreateElement("", "price", "");
xmltext = xmldoc.CreateTextNode("5.95");
xmlelem4.AppendChild(xmltext);
xmldoc.ChildNodes.Item(1).AppendChild(xmlelem1).AppendChild(xmlelem4);
xmldoc.Save(Server.MapPath("bookstore.xml")); //保存
}
//创建xml文件方法二
protected void btn2_OnClick(object sender, EventArgs e)
{
XmlDocument xmldoc = new XmlDocument(); //创建空的XML文档
xmldoc.LoadXml("" +
"" +
"" +
"Oberon's Legacy " +
"Corets, Eva " +
"5.95 " +
" " +
" ");
xmldoc.Save(Server.MapPath("bookstore2.xml")); //保存
}
效果如下：
Oberon's Legacy
Corets, Eva
5.95
不是我想要的网站地图xml文件。
2.以下是我自己根据实际情况写的
using System;
using System.Collections.Generic;
using System.IO;
using System.Threading;
using System.Xml;
namespace Helper
{
public class SitemapXml
{
private const string Xmlns = "http://www.sitemaps.org/schemas/sitemap/0.9";

//保存创建好的XML文档
string filename = saveFileName + ".xml";
string path = System.Web.HttpContext.Current.Server.MapPath(savePath) + filename;
//先创建XML,返回路径
var xmldoc = new XmlDocument();
//加入XML的声明段落,

continue;
}
XmlElement xe1 = xmldoc.CreateElement("url");//创建一个节点

}
try

xmldoc.AppendChild(xmlelem);
xmldoc.Save(path);
