. NET build Site Map Sitemap.xml

1. Here is demo, draw on others to generate XML

Create an XML file method protected void Btn1_onclick (object sender, EventArgs e) {XmlText XmlText;         XmlDocument xmldoc = new XmlDocument (); Add the Declaration of the XML paragraph XmlNode XmlNode = xmldoc.          Createxmldeclaration ("1.0", "gb2312", null); XmlDoc.         AppendChild (XmlNode); Add a root element XmlElement Xmlelem = xmldoc.          CreateElement ("", "bookstore", ""); XmlText = xmldoc.          createTextNode (""); Xmlelem.          AppendChild (xmltext); XmlDoc.         AppendChild (Xmlelem); Add a child element XmlElement xmlelem1 = xmldoc.          CreateElement ("", "book", ""); XmlText = xmldoc.          createTextNode (""); Xmlelem1.         AppendChild (xmltext); Adds two attribute xmlelem1 to the child element "book".          SetAttribute ("Genre", "" "," Fantasy "); Xmlelem1.          SetAttribute ("ISBN", "2-3631-4"); XmlDoc. Childnodes.item (1).         AppendChild (XMLELEM1); Creates a child element of three child elements 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"));  Save}//Create XML file method two protected void Btn2_onclick (object sender, EventArgs e) {XmlDocument xmldoc = new XmlDocument (); Creates an empty XML document XMLDOC. LOADXML ("<?xml version= ' 1.0 ' encoding= ' gb2312 '?>" + "<bookstore>" + "<book genre= ' fantasy ' isbn= ' 2-3631-4 ' &Gt; "+" <title>oberon ' s legacy</title> "+" <author>corets, eva</author> "+          "<price>5.95</price>" + "</book>" + "</bookstore>"); XmlDoc. Save (Server.MapPath ("Bookstore2.xml"));  Save

If this is the case:

<?xml version= "1.0" encoding= "gb2312"?>  <bookstore>   <book genre= "Fantasy" isbn= "2-3631-4" >   <title>oberon ' s legacy</title>    <author>corets, eva</author>    <price >5.95</price>    </book> </bookstore>

Not the site map XML file I want.

2. The following is my own according to the actual situation written

The resulting result is:
