I have read that someone couldn't get Robert Fosters Sitemap to update with Articulates Blog posts Soooo I did a bit of code because I needed it too.

I added a property called ArticulateID in the sitemap document type which allows me to set an id for the sitemap to pickup that id and include the blog posts as well. I run multiple sites so I just simple add sitemap and articulate to the root and get articulates id and put it in the sitemap property. Pretty easy I think. Anyway Umbraco formatted this code a bit weird so hopefully you'll be able to replicate.

@using Articulate

@using Articulate.Models @using System.Linq @inherits Umbraco.Web.Mvc.UmbracoTemplatePage

@{Layout = null;} @helper ListChildNodes(IPublishedContent startNode) { Response.ContentType = "text/xml"; const int maxLevelForSiteMap = 1000; foreach(var node in startNode.Children .Where(n => n.IsVisible() && n.TemplateId > 0 && !Umbraco.IsProtected(n.Id, n.Path) && (!n.HasProperty("searchEngineSiteMapHide") || !n.GetPropertyValue

@helper ListArticulateNodes() {

if(@Model.Content.GetPropertyValue("ArticleNodeID") != "")
{

var newsroot = Umbraco.TypedContent(@Model.Content.GetPropertyValue("ArticleNodeID"));
var blogArchive = newsroot.Children.First();

Response.ContentType = "text/xml";
const int maxLevelForSiteMap = 1000;

foreach(var node in blogArchive.Children)

{
<url>
    <loc>@(((IPublishedContent)node).UrlWithDomain())</loc>
    <lastmod>@node.UpdateDate.ToString("s")+00:00</lastmod>
</url>
    if (node.Level <= maxLevelForSiteMap)
    {
        @ListChildNodes(node)

    }

}

} }
