<SCRIPT runat="server">

    Response.Write(SiteMap.RootNode.Url + "<BR>");
    Response.Write(SiteMap.RootNode.Title + "<BR>");

    foreach (SiteMapNode sitemapnode in SiteMap.RootNode.ChildNodes)

        // Iterate through the ChildNodes SiteMapNodesCollection
        // maintained by the RootNode.
        Response.Write(sitemapnode.Url + "<BR>" );
    }

    IEnumerator providers = SiteMap.Providers.GetEnumerator();
    while (providers.MoveNext())
    {
        Response.Write(providers.Current);
        Response.Write("   ");
        Response.Write("<BR>");

    Response.Write(SiteMap.RootNode.Url & "<BR>")

    Dim sitemapnode As SiteMapNode
    For Each sitemapnode In SiteMap.RootNode.ChildNodes
        ' Iterate through the ChildNodes SiteMapNodesCollection
        ' maintained by the RootNode.
        Response.Write(sitemapnode.Url & "<BR>" )
    Next

    Dim providers As IDictionaryEnumerator = SiteMap.Providers.GetEnumerator()
    While (providers.MoveNext())
        Response.Write(providers.Current)
        Response.Write("   ")
        Response.Write("<BR>")

Remarks

By default, the XmlSiteMapProvider object is used and site navigation data is loaded from the Web.sitemap file that is located in the root directory of the site. This is identified in the management classes that manage the site navigation configuration and the site map configuration section of the Web.config files. By default, it is an instance of the XmlSiteMapProvider class, which uses the Web.sitemap file as its persistent store. However, you can implement your own site map storage and configuration scheme by writing a class that implements the abstract SiteMapProvider class. For more information on writing your own provider, see SiteMapProvider.
