Need some help traversing nodes in C#

API Questions

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");
            }

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)";
