Google Map, JavaScript

Protected Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

       Dim xmldoc As New XmlDataDocument()

       Dim fs As New FileStream("D:/output.xml", FileMode.Open, FileAccess.Read)
       xmldoc.Load(fs)
       XmlNode = xmldoc.GetElementsByTagName("Table")
       For i = 0 To XmlNode.Count - 1

           d = XmlNode(i).ChildNodes.Item(0).InnerText.Trim()
           coord = XmlNode(i).ChildNodes.Item(1).InnerText.Trim() & "," & XmlNode(i).ChildNodes.Item(2).InnerText.Trim()

           l1 = XmlNode(i).ChildNodes.Item(1).InnerText.Trim()
           l2 = xmlnode(i).ChildNodes.Item(2).InnerText.Trim().

I pass this l1 and l2 value in javascript which plot them on map.
Below is js function:

   function initialize() {
                  
                       var lat = '<%=l1%>';
                       var lon = '<%=l2%>';
                       var myLatlng = new google.maps.LatLng(lat, lon) // This is used to center the map to show our markers
                       var mapOptions = {
                           center: myLatlng,
                           zoom: 3,
                           mapTypeId: google.maps.MapTypeId.ROADMAP,
                           marker: true
                       };
                       var map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);

                       var marker = new google.maps.Marker({
                           position: myLatlng
                       });

                       marker.setMap(map);
                   }
