Querying by document type (and child types) recursively

Hi,

I have a sort of a article setup, where I have a Article document type, and I create those articls in Date folders (auto-generated folders based on a date value).

But I also have child types derived from this article type, for example review is a child type of article. Thought I'd be smart and have this set up like so, so I could both list based on the parten type, and differentiate on the types.

So I could have a tree like this:

Home´
- 2010
- 11
- Some Article
- Another Article
- A Review of something (kinda like a article)
- 12
- Yet anohter Article
- Anohter silly Review

Let's that I want to list newsest 5 Articles (including child types). Also I'd like to just list by exact type (just the Articles and just the Reviews etc.)

Any nifty ideas ? :)

Something like this:

@Model.AncestorOrSelf(1).DescendantsOrSelf("ArticleTypeAlias").OrderBy("CreateDate desc").Take(5)

This will give you all of the articles.

But you can't get descendants of different node types. For that I would just put them in a generic list and do a for-each on the list:

   @{
        var myList = new List<umbraco.MacroEngines.DynamicNode>();
        foreach (dynamic page in @Model.AncestorOrSelf(1).DescendantsOrSelf().OrderBy("CreateDate desc")) {
            if(page.NodeTypeAlias == "OneType" || page.NodeTypeAlias == "OtherType")
            {
                myList.Add(page);
            }
        }
    }

    @foreach(dynamic page in myList.Take(5)) {
        <span>@page.Name</span>
    }
