用ASP生成的网站地图聚到问题，请教高人解决。

我用ASP代码来生成网站代码，asp代码如下：
<%@ CODEPAGE=65001 %>
<% Response.CharSet="UTF-8" %>
<% Response.Buffer=True %>
<%
' For www. sitemaps xml

Server.ScriptTimeout = 50000
session(“server”) = “www.” ’域名
vDir = “/”‘制作SiteMap的目录,相对根目录 全站为”/”

Set objfso = CreateObject(“Scripting.FileSystemObject”)
root = Server.MapPath(vDir)’”D:\askmyself“‘Server.MapPath(vDir)
str = ”<?xml version=”"1.0″” encoding=”"UTF-8″”?>” & vbcrlf
str = str & ”<urlset xmlns=”"http://www.″”>” & vbcrlf
str = str & ”<!–Google Site Map File Generated by http://www. ”& now() &”–>” & vbcrlf

Set objFolder = objFSO.GetFolder(root)
Set colFiles = objFolder.Files
For Each objFile In colFiles
  str = str & getfilelink(objFile.Path,objfile.dateLastmodified) & vbcrlf
Next
ShowSubFolders(objFolder)

str = str & ”</urlset>” & vbcrlf
Set fso = Nothing

Set objStream = Server.CreateObject(“ADODB.Stream”)
With objStream
  .Open
  .CharSet = ”utf-8″
  .Position = objStream.Size
  .WriteText = str
  .SaveToFile Server.Mappath(“/sitemap.xml”),2 ’生成的XML文件名
  .Close

Set objStream = Nothing
If Not Err Then
  Response.Write(“<script>alert(‘成功生成站点地图!’);history.back();</script>”)

vDir = “/”‘制作SiteMap的目录,相对根目录 全站为”/”
我直接用了这个斜杠后，制作的地图是非法的：
http://www.
这样的结果，请高人指教，应该如何设置。
谢谢了。
