How to add a new XML node to file

Need to open an XML file and add a node? It is actually very simple

Here’s how:

Sample XML file:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <Page>
    <Id>1</Id>
    <Name>Default.aspx</Name>
    <Title>Client Management System </Title>
  </Page>
  <Page>
    <Id>2</Id>
    <Name>Login.aspx</Name>
    <Title>Login Page</Title>
   </Page>
  <Page>
 </configuration>

C#

     
            string SeoXmlFile = MapPath("SeoXml.xml");
            //create new instance of XmlDocument
            XmlDocument doc = new XmlDocument();
            //load from file
            doc.Load(SeoXmlFile);
            //create main node
            //create main node
            XmlNode node = doc.CreateNode(XmlNodeType.Element, "Page", null);


            //create the nodes first child
            XmlNode NodeId = doc.CreateElement("Id");
            NodeId.InnerText = "3";

            //create the nodes first child
            XmlNode NodeName = doc.CreateElement("Name");
            NodeName.InnerText = "Contact.aspx" ;
            //create the nodes second child
            XmlNode NodeTitle = doc.CreateElement("Title");
            //set the value
            NodeTitle.InnerText ="Contact Us Page Title";


            // add childes to father
            node.AppendChild(NodeId);
            node.AppendChild(NodeName);
            node.AppendChild(NodeTitle);


            // find the node we want to add the new node to
            doc.DocumentElement.AppendChild(node);
            // append the new node
          
            // save the file
            doc.Save(SeoXmlFile);
            LoadSeoGrid();

Now show what will be the new generated XML after Adding node

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <Page>
    <Id>1</Id>
    <Name>Default.aspx</Name>
    <Title>Client Management System </Title>
  </Page>
  <Page>
    <Id>2</Id>
    <Name>Login.aspx</Name>
    <Title>Login Page</Title>
   </Page>
  <Page>
  <Page>
    <Id>3</Id>
    <Name>Contact.aspxx</Name>
    <Title>Contact Us Page Title</Title>
   </Page>
  <Page>
 </configuration>
