  XMLR = XMLRR New list of dim writer ("string") urlList.Add ("link1") urlList.Add ("link2") urlList.Add ("link3") Author as the seat (file location + "Statistics 3 XML"). Light-Start Document () Writer Merge start element ("urlset") author. To type "string" ("xmlns", "http://www.sitemaps.org/schemas/sitemap/0.9") as a string author of URL for each URL. Merge start element ("Url") author. Write element string ("People", a URL) author. After writing. () Next author. Writer Writer (Author). WriteEndDocument () Writer Close ()
