这样的xml如何构造出来

Question

<tree id="0">
<item text="Books" id="books" open="1" im0="tombs.gif" im1="tombs.gif" im2="iconSafe.gif" call="1" select="1">
<item text="Mystery &amp; Thrillers" id="mystery" im0="folderClosed.gif" im1="folderOpen.gif" im2="folderClosed.gif">
<item text="Lawrence Block" id="lb" im0="book_titel.gif" im1="book.gif" im2="book_titel.gif">
<item text="All the Flowers Are Dying" id="lb_1" im0="book_titel.gif" im1="book.gif" im2="book_titel.gif"/>
<item text="The Burglar on the Prowl" id="lb_2" im0="book_titel.gif" im1="book.gif" im2="book_titel.gif"/>
<item text="The Plot Thickens" id="lb_3" im0="book_titel.gif" im1="book.gif" im2="book_titel.gif"/>
<item text="Grifter's Game" id="lb_4" im0="book_titel.gif" im1="book.gif" im2="book_titel.gif"/>
<item text="The Burglar Who Thought He Was Bogart" id="lb_5" im0="book_titel.gif" im1="book.gif" im2="book_titel.gif"/>
</item>
</item>
</item>如果使用XmlDocument，那么text="Lawrence Block" id="lb" im0="book_titel.gif" im1="book.gif" im2="book_titel.gif"这些应该怎么添加进去。

xmldocument 设置xmlnode的arrtibutes
public static void Insert(string path, string node, string element, string attribute, string value)
        {
            try
            {
                XmlDocument doc = new XmlDocument();
                doc.Load(path);
                XmlNode xn = doc.SelectSingleNode(node);
                if (element.Equals(""))
                {
                    if (!attribute.Equals(""))
                    {
                        XmlElement xe = (XmlElement)xn;
                        xe.SetAttribute(attribute, value);
                    }
                }
                else
                {
                    XmlElement xe = doc.CreateElement(element);
                    if (attribute.Equals(""))
                    {
                        xe.InnerText = value;
                    }
                    else
                    {
                        xe.SetAttribute(attribute, value);
                    }
                    xn.AppendChild(xe);
                }
                doc.Save(path);
            }
            catch { }
        }
