My code:
<div id="navigation">
                [list]


                    <asp:Repeater runat="server" ID="menu" >
                        <ItemTemplate>
                            <li>
                                <asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl="....."><%# If(eval("parentID")==0) eval("Name") %></asp:HyperLink>

                                <asp:Repeater ID="Repeater1" runat="server" >
                                    <HeaderTemplate>
                                        [list]
                                    </HeaderTemplate>

                                    <ItemTemplate>
                                        <li>
                                            <asp:HyperLink ID="HyperLink2" runat="server" NavigateUrl="...."><%# Eval("Name") %></asp:HyperLink>
                                        </li>
                                    </ItemTemplate>

                                    <FooterTemplate>
                                        </ul>
                                    </FooterTemplate>
                                </asp:Repeater>
                            </li>
                        </ItemTemplate>
                    </asp:Repeater>
                </ul>


            </div>

behin code:

private string xmlSource = string.Empty;

        protected void Page_Load(object sender, System.EventArgs e)
        {
            rptMenu.DataSource = GetMenu();
            rptMenu.DataBind();
        }

        private ArrayList GetMenu()
        {
            try
            {
                xmlSource = lblXmlSource.Text;
                xmlSource = Server.MapPath(xmlSource);
                XmlDocument doc = new XmlDocument();
                doc.Load(xmlSource);

                ArrayList menu = new ArrayList();

                XmlNodeList list = doc.SelectNodes("Data/MenuItem");
                foreach (XmlNode node in list)
                {
                    try
                    {
                        int id = int.Parse(node.SelectSingleNode("ID").InnerText);
                        string name = node.SelectSingleNode("Text").InnerText;
                        int parentID = int.Parse(node.SelectSingleNode("ParentID").InnerT ext);
                        string cssClass = node.SelectSingleNode("CssClass").InnerText;
                        MenuItems item = new MenuItems(id, parentID, name, cssClass, string.Empty, true);
                        menu.Add(item);
                    }
                    catch
                    {
                        continue;
                    }
                }

                return menu;
            }
            catch (Exception ex)
            {
                return null;
            }
        }

What about using the asp:xml control with an XSL transformation?
