Adding child nodes in XML

Question

I'm making a shortcut program for my daily games I do play. It's sorta like mobile phone folders work just so that you know what I mean.

So far I've come to:

    private void addGame(object sender, EventArgs e)
    {
        string name      = string.Empty;
        string game_path = string.Empty;
        string icon_path = string.Empty;


        OpenFileDialog ofdGamePath = new OpenFileDialog();
        ofdGamePath.Title = "Choose the game...";

        OpenFileDialog ofdIconPath = new OpenFileDialog();
        ofdIconPath.Title = "Choose the icon...";

        if (ofdGamePath.ShowDialog() == DialogResult.OK)
        {
            game_path = ofdGamePath.FileName;
        }

        if (ofdIconPath.ShowDialog() == DialogResult.OK)
        {
            icon_path = ofdIconPath.FileName;
        }
    }

Where I currently stuck is the saving to XML path. While on my research I found alot "overkill" solutions which absolutely not fit my scope.

My games.xml looks like the following:

    <Games>
      <game name="" path="" icon="" />
    </Games>

Also reading the file isn't a problem either. Here's the code I use for reading it:

        XmlDocument xdoc = new XmlDocument();
        xdoc.Load(Application.StartupPath + @"\" + args[1]);
        XmlNodeList elemList = xdoc.GetElementsByTagName("game");

        for (int i = 0; i < elemList.Count; i++)
        {
            string name = elemList[i].Attributes["name"].Value;
            string game_path = elemList[i].Attributes["path"].Value;
            string icon_path = elemList[i].Attributes["icon"].Value;
        }

Could anyone direct me into the right direction on how to simply save that one line of XML? Much thanks!

Answer 1

       using (var writer = XmlTextWriter.Create("MyFile.xml"))elemList[i].WriteTo(writer);

Answer 2

Okay so I found what I needed!

        XmlDocument doc = new XmlDocument();
        doc.Load(Application.StartupPath + @"\" + args[1]);
        XmlElement el = (XmlElement)doc.SelectSingleNode("Applications");

        if (el != null)
        {
            XmlElement elem = doc.CreateElement("app");
            elem.SetAttribute("name", "name online game here");
            elem.SetAttribute("path", "123123123");
            elem.SetAttribute("icon", "test");

            el.AppendChild(elem);
        }

        doc.Save(Application.StartupPath + @"\" + args[1]);

Resulting in:

  <app name="name online game here" path="123123123" icon="test" />
