Use XML Document to Query for specific nodes

<%@ Page Language="C#" %>
<%@ Import Namespace="System.Xml" %>
<script runat="server">
    void Page_Load(object sender, EventArgs e)
    {
        string xmlPath = MapPath("Books.xml");
        XmlDocument doc = new XmlDocument();
        //doc.Load(xmlPath);        
        doc.LoadXml("<employees>" +
                    "<employee id="1">" +    
                    "<firstName>First Name</firstName>" + 
                    "<lastName>Last Name</lastName>" +

        XmlNodeList titleList = doc.GetElementsByTagName("employee");
        Response.Write("Employee: " + "<br>");
        foreach (XmlNode node in titleList)
        {
            Response.Write("Title : " + node.FirstChild.Value + "<br>");

        //Get reference to the first author node in the XML file
