用xmldocument创建一个Xml文件

 

XML 文件:

<?xml version="1.0" encoding="utf-8"?>

<CategoryList>

<Category ID="01">

<MainCategory>XML</MainCategory>

<Description>This is a list my XML articles.</Description>

<Active>true</Active>

</Category>

</CategoryList>

代码如下:

<%@ Import Namespace="System.Data" %>

<%@ Import Namespace="System.Xml" %>

<%@ Page Language="C#" Debug="true" %>

<script  runat="server">

void Page_Load(object sender, System.EventArgs e){

if(!Page.IsPostBack){

XmlDocument xmlDoc = new XmlDocument();

// Write down the XML declaration

XmlDeclaration xmlDeclaration = xmlDoc.CreateXmlDeclaration("1.0","utf-8",null);

// Create the root element

XmlElement rootNode  = xmlDoc.CreateElement("CategoryList");

xmlDoc.InsertBefore(xmlDeclaration, xmlDoc.DocumentElement);

xmlDoc.AppendChild(rootNode);

// Create a new <Category> element and add it to the root node

XmlElement parentNode  = xmlDoc.CreateElement("Category");

// Set attribute name and value!

parentNode.SetAttribute("ID", "01");

xmlDoc.DocumentElement.PrependChild(parentNode);

// Create the required nodes

XmlElement mainNode  = xmlDoc.CreateElement("MainCategory");

XmlElement descNode  = xmlDoc.CreateElement("Description");

XmlElement activeNode  = xmlDoc.CreateElement("Active");

// retrieve the text

XmlText categoryText= xmlDoc.CreateTextNode("XML");

XmlText descText  = xmlDoc.CreateTextNode("This is a list my XML articles.");

XmlText activeText  = xmlDoc.CreateTextNode("true");

// append the nodes to the parentNode without the value

parentNode.AppendChild(mainNode);

parentNode.AppendChild(descNode);

parentNode.AppendChild(activeNode);

// save the value of the fields into the nodes

mainNode.AppendChild(categoryText);

descNode.AppendChild(descText);

activeNode.AppendChild(activeText);

// Save to the XML file

xmlDoc.Save( Server.MapPath("categories.xml"));

Response.Write("XML file created");

}

}

</script>
