Multi node tree picker deserialize
Hello,

I use this with my uComponents url picker:
```
var destination = uComponents.DataTypes.UrlPicker.Dto.UrlPickerState.Deserialize(Model.Content.GetPropertyValue("destination").ToString());
if (!string.IsNullOrWhiteSpace(destination.Url))
{
    // Stuff
}
```
Works like a charm! I'm looking for the same thing with my multi node tree picker here. Is there a fun way to do this?

Here is the piece of code I'm trying to make cooler (maybe I'm just not taking the proper approach...):
```
foreach (var subExpertise in Model.Content.Children)
{
    projects.AddRange(lang.Descendants("Projet").Where(x => ((MNTP)x.AsDynamic().Expertise).nodeId == subExpertise.Id));
}
```
Any help will be appreciated!

Thanks!

This post is a bit old, but I think I can share my experience and workaroud for situations like this.

I tried to find a deserializer as well for MultiNodeTreePicker but couldnt find any, so I created my own which handles the variables in XML format as below:

public static List<Node> GetMultiNodePickerContentItems(string xmlFormatString)
        {
            List<Node> retVal = new List<Node>();

            XmlDocument xdoc = new XmlDocument();
            xdoc.LoadXml(xmlFormatString);

            if (xdoc.FirstChild.Name == "MultiNodePicker")
            {
                foreach (XmlNode xnod in xdoc.FirstChild.ChildNodes)
                {
                    if (xnod.Name == "nodeId")
                    {
                        int nodeId = -1;
                        if (Int32.TryParse(xnod.InnerText, out nodeId)) retVal.Add(new Node(nodeId));
                    }
                }
            }
            return retVal;
        }

And Calling it is like:

foreach (Node linkItemNode in Helper.GetMultiNodePickerContentItems(thisNode.GetProperty("links").Value))
                        {
                            ................
                        }
