Let me answer my own question before someone chips in :-) Just as Niels said, and as I finally got to understand, unique id is not a doctype as we know it. User-created doctypes too uniqueIDs too. But getAllUniqueNodeIdsFromObjectType only filters over a field descibing a much more general "doctype" id, one that was created "before all time" - eg. a "webpage", a "macro", a "stylesheet". So pluging a unique id of a user doctype will always result in an empty result set.

Perhaps something along the lines of how I initially understood the method will be possible one day :-) But until then it's good ol' recursion.

Are you looking to get the NodeIds of all published content nodes by their DocumentType Alias?

In that case you can do this:

var nodeIds = GetNodeIdsByAlias("ContentPage", 0)

        /// <summary>
        /// Get List of Node IDs by DocumentType Alias.
        /// </summary>
        /// <param name="nodeTypeAlias">DocumentType alias to match.</param>
        /// <param name="startNodeId">Select from this Nodes descendants.</param>
        public static List<int> GetNodeIdsByAlias(string nodeTypeAlias, int startNodeId)
        {
            List<int> nodeIds = new List<int>();
            string start = startNodeId > 0 ? string.Format("//node[@id = {0}]", startNodeId) : "";
            XPathNodeIterator it = umbraco.library.GetXmlNodeByXPath(string.Format(start + "//node[@nodeTypeAlias = '{0}']", nodeTypeAlias));
            while (it.MoveNext())
            {
                int nodeId = Convert.ToInt32(it.Current.GetAttribute("id", it.Current.NamespaceURI));
                nodeIds.Add(nodeId);
            }
            return nodeIds;
        }

Hi,

above, the example is for published nodes, however i need the oposite ( Not published )..

What i need change for get that?

thanks

is working on a reply...
