To inspect the Workflow tree, we can use WorkflowInspectServices:

   /// <summary>
   /// Use this method to list all sub activities
   /// WorkflowInspectServices: Provides methods 
   /// for working with the runtime metadata for an activity tree.
   /// </summary>
   /// <param name="rootWF"></param>
   /// <param name="indent"></param>
   private static void InspectWorkflow(Activity rootWF, int indent) {
       IEnumerator<Activity> activities = 
            WorkflowInspectionServices.GetActivities(rootWF).GetEnumerator();
       Console.WriteLine(new string(' ', indent) + rootWF.DisplayName + " id:" 
                                     + rootWF.Id);
       while (activities.MoveNext()) {
            InspectWorkflow(activities.Current, indent + 2);
       }
   }

To Inspect workflow Variables and Arguments, we can use ActivityBuilder:

   /// <summary>
   /// Use this method to list all Variables, InArguments and OutArguments
   /// </summary>
   private static void LoadWFFromXaml(){
       string xamlWorkflow =File.ReadAllText(@"Path\Workflow1.xaml");
       StringReader sr = new StringReader(xamlWorkflow);
       XamlXmlReader xxr = new XamlXmlReader(sr);
       XamlReader xr = ActivityXamlServices.CreateBuilderReader(xxr);
       ActivityBuilder ab = XamlServices.Load(xr) as ActivityBuilder;

       foreach (var p in ab.Properties) {
          Console.WriteLine("Name:" + p.Name);
          Console.WriteLine("Type:" + p.Type);
          Console.WriteLine("Attribute:" + p.Attributes);
          Console.WriteLine("Value:" + p.Value);             
          Console.WriteLine("---------------------------------");
       }
   }
