I solved it this way, but I don't know if it is the best:

            XmlDocument xmlDoc = new XmlDocument();
            xmlDoc.Load(variabili.direcotry_db + "document.xml");

            XmlNodeList CList = xmlDoc.GetElementsByTagName("Val1");
            for (int i = 0; i < CList.Count; i++)
            {
                TextBox1.Text = CList[i].InnerText.ToString();
            }
            XmlNodeList CList2 = xmlDoc.GetElementsByTagName("Val2");
            for (int i = 0; i < CList2.Count; i++)
            {
                TextBox2.Text = CList2[i].InnerText.ToString();
            }
            XmlNodeList CList3 = xmlDoc.GetElementsByTagName("Val3");
            for (int i = 0; i < CList3.Count; i++)
            {
                TextBox3.Text = CList3[i].InnerText.ToString();
            }
