Hey, i have created a sitemap with help from: https://our.umbraco.com/documentation/Tutorials/Creating-an-XML-Site-Map/

I ended up with this:

How can i only show the urls that returns response code 200 ?

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage

@{Layout = null;

string blacklistedDocumentTypeList = Model.Content.GetPropertyValue<string>("blacklistedDocumentTypes");
string[] blackListedDocumentTypes = (!String.IsNullOrEmpty(blacklistedDocumentTypeList)) ? blacklistedDocumentTypeList.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries) : new string[] { };
int maxSiteMapDepth = Model.Content.HasValue("maxSiteMapDepth") ? Model.Content.GetPropertyValue<int>("maxSiteMapDepth") : int.MaxValue;
IPublishedContent siteHomePage = Model.Content.Parent;

}

@{ @helper RenderSiteMapUrlEntry(IPublishedContent node) { // with the relative priority, this is a per page setting, so we're not passing true var priority = node.GetPropertyValue

    if (String.IsNullOrEmpty(priority))
    {
        priority = "0.4";
    }
    <url>
        <loc>@EnsureUrlStartsWithDomain(node.UrlWithDomain())</loc>
        <lastmod>@(string.Format("{0:s}+00:00", node.UpdateDate))</lastmod>
        <priority>@priority.Replace(",", ".")</priority>
    </url>
}

@helper RenderSiteMapUrlEntriesForChildren(IPublishedContent parentPage, int maxSiteMapDepth, string[] documentTypeBlacklist)
{
    foreach (var page in parentPage.Children.Where(f => !documentTypeBlacklist.Contains(f.DocumentTypeAlias) && !f.GetPropertyValue<bool>("hideFromSiteMap")))
    {
        @RenderSiteMapUrlEntry(page)
        if (page.Level < maxSiteMapDepth && page.Children.Any(f => !documentTypeBlacklist.Contains(f.DocumentTypeAlias) && !f.GetPropertyValue<bool>("hideFromSiteMap")))
        {
            @RenderSiteMapUrlEntriesForChildren(page, maxSiteMapDepth, documentTypeBlacklist)
        }
    }
}

}

@functions { private static string EnsureUrlStartsWithDomain(string url) { if (url.StartsWith("http")) { return url; } else { // whatever makes sense for your site here... var domainPrefix = string.Format("https://{0}/", HttpContext.Current.Request.ServerVariables["HTTP_HOST"]); return domainPrefix + url; } } }
