    Getting strongly typed content from IPublishedcontent

    I am trying to create a xml site map.

    And i was wondering, is there a better way or more "correct" way of getting the "HideFromSitemap" property on each page ? The hidefromsitemap is from a composition that is present on all pages.

    It just seems wrong that i first have to check for it, and then cast it to IConfiguration.

    Is there a better and or smarter way of doing this ?

    My Code: 

    var home = CurrentPage.AncestorOrSelf<Home>(); // find the home node.
            var children = home.Descendants(); // get needed content from each page.
            var sitemapList = new List<SitemapModel>(); //initiate new list.


            foreach (var item in children)
            {
                if (item is IConfiguration)
                {
                    var config = (IConfiguration)item;

                    if (config.HideFromSitemap)
                    {
                        var sitemapItem = new SitemapModel()
                        {
                            Loc = item.UrlAbsolute(),
                            LastUpdated = item.UpdateDate,
                            Priority = "0.5",
                            ChangeFreq = "weekly"
                        };
                        sitemapList.Add(sitemapItem);
                    }
                }
            }

    Hi André

    You should be able to do like this

    var children = home.Descendants<IConfiguration>(x => x.HideFromSitemap); // get needed content from each page, cast them to IConfiguration and filter on HideFromSitemap.
var sitemapList = children.Select(x => new SitemapModel(){
    Loc = x.UrlAbsolute(),
    LastUpdated = x.UpdateDate,
    Priority = "0.5",
    ChangeFreq = "weekly"
});

    If you have any nodes not implementing the Configuration composition, they will simply not show up in your children list

    I was able to do it like this, based on your response : 

    var home = this.nodeHelper.GetFrontpage(); // find the home node.
            var children = home.Descendants<IConfiguration>().Where(x => x.HideFromSitemap == false); // get needed content from each page.
            var sitemapList = new List<SitemapModel>(); //initiate new list.

            foreach (var item in children)
            {
                var sitemapItem = new SitemapModel()
                {
                    Loc = item.UrlAbsolute(),
                    LastUpdated = item.UpdateDate,
                    Priority = "0.5",
                    ChangeFreq = "weekly"
                };
                sitemapList.Add(sitemapItem);
            }

    But for some reason it would not let me do as you did directly. 

    home.Descendants<IConfiguration>(x => x.HideFromSitemap);

    Are you using umbraco 8 as well ?
