    Need some help traversing nodes in C#

    Here's the situation:

     

    I have  List of nodes retreived using uquery.

    For each of those nodes, I need to access the node ID's contained in a multi content picker.

    For each of those node ID's, I need to retrieve a property form that node and append it to a string.

     

    List<Node> nodes = uQuery.GetNodesByXPath("//*[@id = '1343' or @id = '1103']//*");
                    int sort = 0;
                    foreach (Node item in nodes)
                    {          
              string propertyList = "";
              //Here is where I need help the rest is pseudo code
                List<ContentID> ids = Node.getProperty("NodePicker")
             foreach (ContentID id in ids) {
                    Node newContent = new Node(id);
                    propertyList += newContent.getProperty("associatedProperty").Value + ",";
              }
                     }

    Any help would be appreciated.

    Thanks!

    Hi,

    Are you storing your MNTP values as XML or CSV?  If XML, something like this should work (not tested):

    (using uComponents.Core.uQueryExtensions)

                string nodesList = item.GetPropertyValue<string>("NodePicker");

                XmlDocument xd = new XmlDocument();
                xd.LoadXml(nodesList);
                foreach (XmlElement value in xd.SelectNodes("/MultiNodePicker/nodeId"))
                {
                    Node newContent = new Node(Convert.ToInt32(value.InnerText));
                    propertyList += newContent.GetPropertyValue<string>("associatedProperty");
                }

    -Tom

    If you're storing as CSV, you can use something like:

                string[] nodesList = item.GetPropertyValue("NodePicker")<string>.Split(',');

            foreach (string value in nodesList)
            {
                Node newContent = new Node(Convert.ToInt32(value));
                propertyList += newContent.GetPropertyValue("associatedProperty");
            }

    Hi,

    Sorry a bit late to aswer this, but thought I'd mention that uQuery also has methods to return node collections from the stored Xml / Csv values (in this case the "NodePicker"  property).

    List<Node> nodes = uQuery.GetNodesByXPath("//*[@id = '1343' or @id = '1103']//*");
    List<Node> pickedNodes;
    StringBuilder stringBuilder = new StringBuilder();

    foreach(Node node in nodes)
    {
      pickedNodes = uQuery.GetNodesByXml(node.GetProperty<string>("NodePicker");

      foreach (Node pickedNode in pickedNodes)
      {
        stringBuilder.Append(pickedNode.GetProperty<string>("associatedProperty") + ", ");
      }
    }

    If the MNTP is storing a csv, then:

    pickedNodes = uQuery.GetNodesByXml(node.GetProperty<string>("NodePicker");

    can be replaced with:

    pickedNodes = uQuery.GetNodesByCsv(node.GetProperty<string>("NodePicker)";
