Read/Find the ID = "IiY+D4SIrRpXtEUUu0uy0j1G0LdUJ9bWPj6+ZvO24yE2szPHUFXMfYXirGmWC7aO"
and update <HighestBid>1000</HighestBid>

How can I do that by using XMLDocument Object in c#?

Hi,

try this code

 

 public void UpdateXmlFile()
        {
            XmlDocument myXmlDocument = new XmlDocument();
            string fileName = @"D:\Auctions.xml";
            myXmlDocument.Load(fileName);

            XmlNode node = myXmlDocument.DocumentElement;

            foreach (XmlNode node1 in node.ChildNodes)
            {
                foreach (XmlNode node2 in node1.ChildNodes)
                {
                    if (node2.Name == "ID")
                    {
                        string nodeValue = node2.InnerText; // Get the ID Value
                    }

                    //Update the Node
                    if (node2.Name == "HighestBid")
                    {
                        // Update the value
                        int newValue = 1000;
                        node2.InnerText = newValue.ToString();
                    }
                }
            }

            //Save the changes to New File
            myXmlDocument.Save(@"D:\a1.xml");

            //Save the Existing File
            myXmlDocument.Save(fileName);
        }
