Need To get path tags from nested relationship and add it to variable

everybody, I need to get pathtags and add it to a variable so I can replace it with

['XML','PHP','CSS3']

$Paths= Path::with(['ProgrammingField','pathtags' => function ($q) 
   {$q->with(['Tasks' => function ($q) 
       {$q->has('tasktags', '=', 2)->orderBy('id', 'ASC')
       ->whereDoesntHave('tasktags',
       function ($query)  {
           $query->whereNotIn('name', ['XML','PHP','CSS3']);
       }
   )
           ->with('tasktags')->orderBy('id', 'DESC');
       }]);
   }])
   ->whereIn('id', $pathId)->get();
