Question

I’m trying to create a sitemap for my MOSS publishing site, i’ve got two approaches but seem to be stuck with both.

My first approach is to use the PortalSiteMapProvider, which is already created and nicely cached…

PublishingWeb rootWeb = PublishingWeb.GetPublishingWeb(SPContext.Current.Site.RootWeb);

//Get the URL of the default page in the web
string defaultPageUrl = rootWeb.DefaultPage.ServerRelativeUrl;

PortalListItemSiteMapNode webNode = (PortalListItemSiteMapNode)PortalSiteMapProvider.CurrentNavSiteMapProviderNoEncode.FindSiteMapNode(defaultPageUrl);

HttpContext.Current.Response.Output.WriteLine("Top Level: " + webNode.Title.ToString() + "<br />");

//iterate through each one of the pages and subsites
foreach (SiteMapNode smnTopLevelItem in webNode.ParentNode.ChildNodes)
{

    HttpContext.Current.Response.Output.WriteLine(smnTopLevelItem.Title.ToString() + "<br />");

    //if the current sitemap has children, create a submenu for it
    if (smnTopLevelItem.HasChildNodes)
    {
        foreach (SiteMapNode smnChildItem in smnTopLevelItem.ChildNodes)
        {
         HttpContext.Current.Response.Output.WriteLine(smnChildItem.Title.ToString() + "<br />");
        }
    }
}

HttpContext.Current.Response.End();

but this seems to return everything in the site collection (e.g. lists, surverys). I only want to show the Sharepoint webs.

My other approach was to use this piece of code..

SPSite siteCollection = new SPSite("http://example.org");
SPWebCollection sites = siteCollection.AllWebs;
foreach (SPWeb site in sites)
{
    Console.WriteLine(site.Title.ToString() + " " + site.ServerRelativeUrl.ToString());
}

Which is perfect, apart from the problem of returning all the webs in a flat list.

Ideally I want to be able to add indentation to show child webs.

thanks for the replys everyone, this is what I came up with

        public ListSiteMap()
    {
        PortalSiteMapProvider portalProvider1 = PortalSiteMapProvider.WebSiteMapProvider;
        portalProvider1.DynamicChildLimit = 0;
        portalProvider1.EncodeOutput = true;

        SPWeb web = SPContext.Current.Site.RootWeb;

        PortalSiteMapNode webNode = (PortalSiteMapNode)portalProvider1.FindSiteMapNode(web.ServerRelativeUrl);

        if (webNode == null || webNode.Type != NodeTypes.Area) return;

        Console.WriteLine(webNode.Title.ToString() + " - " + webNode.Description.ToString());

        // get the child nodes (sub sites)
        ProcessSubWeb(webNode);
    }

    private void ProcessSubWeb(PortalSiteMapNode webNode)
    {
        foreach (PortalSiteMapNode childNode in webNode.ChildNodes)
        {
            Console.WriteLine(childNode.Title.ToString() + " - " + childNode.Description.ToString());

            //if the current web has children, call method again
            if (childNode.HasChildNodes)
            {
                ProcessSubWeb(childNode);
            }
        }
    }
