Question

How do i write something in the innertext of my xml file

i am able to read the particualar tag from the file like this:

 protected void Page_Load(object sender, EventArgs e)
    {// this is to read from xml.
        if (!Page.IsPostBack)
        {
            XmlDocument xmlDoc = new XmlDocument();

            xmlDoc.Load(@"C:\configfolder\config.xml");

            XmlNodeList portNo = xmlDoc.GetElementsByTagName("AgentConfigRepository");
            foreach (XmlNode node in portNo)
            {
                XmlElement bookElement = (XmlElement)node;
                string no = bookElement.GetElementsByTagName("OVERRIDE_CONFIG_FILE_NAME")[0].InnerText;
                TextBox1.Text = no;
            }
        }
    }

Now i want to change the value in the innertext of OVERRIDE_CONFIG_FILE_NAME

this is how my xml file looks like:

<?xml version="1.0" encoding="utf-8" standalone="no"?>
<AgentConfigRepository>
  <SERVER_SHARE_SW_DIR_NAME val="singleVal">AgentSW</SERVER_SHARE_SW_DIR_NAME>
  <OVERRIDE_CONFIG_FILE_NAME val="singleVal">override_config.xml</OVERRIDE_CONFIG_FILE_NAME>
  <MAINTAIN_AGENT_SW_LEVEL val="singleVal">1.0</MAINTAIN_AGENT_SW_LEVEL>
  <MAINTAIN_AGENT_SW_PATCH_LEVEL val="singleVal">0</MAINTAIN_AGENT_SW_PATCH_LEVEL>
</AgentConfigRepository>

so i want to change override_config.xml to some other value in the textbox.

any suggestions.. thanks

If you can use XDocument, it becomes pretty trivial:

XDocument xdoc = XDocument.Load(@"C:\configfolder\config.xml");
xdoc.Root.Element("OVERRIDE_CONFIG_FILE_NAME").SetValue("HelloThere");
xdoc.Save(@"C:\so2.xml");
