xml WITH listbox

HI Everybody,

I have this:

 private void btnConnectionStrings_Click(object sender, EventArgs e)
        {
            //if(File.Exists(@"C:\Users\IllesIuliu\Documents\Visual Studio 2010\Projects\WindowsFormsApplication18\GetSelectedID\XML\Configurations.xml"))
            XmlDocument docHallo = new XmlDocument();
            docHallo.Load(@"C:/Users/IllesIuliu/Documents/Visual Studio 2010/Projects/WindowsFormsApplication18/GetSelectedID/XML/Configurations.xml");
            XmlNodeList nodeList = docHallo.GetElementsByTagName("SupplyXMLConnectionString");


            //var items = (from i in .Descendants("item")
            //            select new { Item = i.Element("SEL").Value, Value = i.Element("VALUE").Value }).ToList();

            //listBox1.DataSource = items;
            //listBox1.DisplayMember = "Item";
            //listBox1.ValueMember = "Value";

            foreach (XmlNode node in nodeList)
            {
                listBox1.Items.Add(node);
                //listBox1.SelectedValue = node.ToString();
            }
                
        }

But as output I get this:system.xml.xmlElement

THX for helping
