This article describes how to create XML files. Share it for your reference, as follows:
Method 1: Construct XML documents step by step according to the XML structure.
Implemented through various classes encapsulated in namespace "" in the .Net FrameWork SDK
Method 1: Construct XML documents step by step according to the XML structure.
Implemented through various classes encapsulated in namespace "" in the .Net FrameWork SDK
Method 2: Fix the XML document directly and save it to the file.
Pass the "LoadXml" method in the "XmlDocument" class
.aspx foreground code:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="" Inherits="Default4" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http:///TR/xhtml1/DTD/"> <html xmlns="http:///1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form runat="server"> <div> <asp:Button ID="btn" runat="server" OnClick="btn1_OnClick" Text="The first way to create xml" /><br /> <asp:Button ID="btn2" runat="server" OnClick="btn2_OnClick" Text="The second way to create xml" /> </div> </form> </body> </html>
The .cs background code implementation is as follows:
using System;
using ;
using ;
using ;
using ;
using ;
using ;
public partial class Default4 :
{
protected void Page_Load(object sender, EventArgs e)
{
}
//Create an xml file method one protected void btn1_OnClick(object sender, EventArgs e)
{
XmlText xmltext;
XmlDocument xmldoc = new XmlDocument();
//Addition paragraph to add XML XmlNode xmlnode = ("1.0", "gb2312", null);
(xmlnode);
//Add a root element XmlElement xmlelem = ("", "bookstore", "");
xmltext = ("");
(xmltext);
(xmlelem);
//Add a child element XmlElement xmlelem1 = ("", "book", "");
xmltext = ("");
(xmltext);
//Add two attributes to the child element "book" ("genre", "", "fantasy");
("ISBN", "2-3631-4");
(1).AppendChild(xmlelem1);
//Create the child elements of three child elements XmlElement xmlelem2 = ("", "title", "");
xmltext = ("Oberon's Legacy");
(xmltext);
(1).AppendChild(xmlelem1).AppendChild(xmlelem2);
XmlElement xmlelem3 = ("", "author", "");
xmltext = ("Corets, Eva");
(xmltext);
(1).AppendChild(xmlelem1).AppendChild(xmlelem3);
XmlElement xmlelem4 = ("", "price", "");
xmltext = ("5.95");
(xmltext);
(1).AppendChild(xmlelem1).AppendChild(xmlelem4);
(("")); //save }
//Create xml file method two protected void btn2_OnClick(object sender, EventArgs e)
{
XmlDocument xmldoc = new XmlDocument(); //Create an empty XML document ("<?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>");
(("")); //save }
}
Comparison: The first one is more flexible to create, while the second one is more convenient to create. The final xml file is as follows: (The creation effect of both methods is the same)
<?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>
