Tested this but wont work:

@using umbraco.MacroEngines
@using System.Linq
@using System.Xml.Linq

@{
    var nodes = Model.AncestorOrSelf(1).Descendants("FolderArticle");
}

@foreach(dynamic news in ((DynamicNodeList)nodes).myArticle)
{
    foreach(dynamic n in news)
    {
        <p>@n.Url</p>
    }
}

The reason your code doesnt work is because you call Descendants() in the first line which gives you a DynamicNodeList, then you call Decendants on that. I assume that you only have a single FolderArticles node right?

If so, you need to do something like this...

@{

// get current node
var current = new DynamicNode(Model.Id)

// get a single FolderArticles node
var start = current.AncestorOrSelf(1).Descendants("FolderArticles").Items.Single();

// get descendants of type articlePost
var articles = start.Items.Descendants("articlePost");
}

@foreach(var c in articles)
{
<h2>@n.contentTitle</h2>...
}

If you have multiple FolderArticle nodes then you need to iterate over all of them.

Hope that helps.

ps. you should rename articlePost to ArticlePost.

Hmm won't work, throws an error:

Error loading Razor Script TabTest.cshtml
c:\inetpub\wwwroot\kultmark\macroScripts\TabTest.cshtml(19): error CS1061: 'object' does not contain a definition for 'nodeName' and no extension method 'nodeName' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?)

Where do you have the input from with the .Items.Single() never read about this before.

Greetings

You're now using a DynamicNode object

Sorry n.contentTitle should be n.GetProperty("contentTitle")

You also need using System.Linq

Can you paste your script?

@using umbraco.MacroEngines
@using System.Linq
@using System.Xml.Linq
    
    @{

// get current node
var current = new DynamicNode(Model.Id)

// get a single FolderArticles node
var start = current.AncestorOrSelf(1).Descendants("FolderArticlesl").Items.Single();

// get descendants of type articlePost
var articles = start.Items.Descendants("ArticlePost");
}

@foreach(var c in articles)
{
<h2>@c.GetProperty("contentTitle")/h2>
}

nothing is returned now. The Errors are gone but the content although :). E.G. I have more than one "FolderArticles"

The Structure is the Following:

Content->Locations->Articles

and each Location has its own ArticleArea from Type FolderArticles where the ArticlePost is stored.

is working on a reply...
