to move the solution from skype to the forum:
either IHDEHost.NodeSelectionChanged event for the INode2
or IHDEHost.GetXMLSnippetFromSelection method to receive the xml

thx woei, so far.

as a beginner im struggling with the concept of events in csharp, respectively the syntax to catch them.

found this: The Simplest C# Events Example Imaginable- CodeProject

and this: Delegates for Dummies- CodeProject

dont really get it :(

something like this:

public class MyPlugin: : IPluginEvaluate, IPartImportsSatisfiedNotification
{
  [Import()](Import())
  public IHDEHost FHDEHost;

  private INode2[]() FSelection; //for storing the selection


  public void OnImportsSatisfied() //called on creation
  {
    FHDEHost.NodeSelectionChanged += delegate(object sender, NodeSelectionEventArgs e)
    { 
	FSelection = e.Nodes; 
    };
  }
}

so each time the event is raised, that delegate is executed, which is simply saving the node selection.
