How to just get the parent "name" with LINQ style?

Hi, my json like:

{ "name": "joe",
           "children": [
             {
               "name": "Mary",
               "age": 5
             },
             {
               "name": "Mazy",
               "age": 3
             }
           ]
         }

I want to get just parent name, how should I do?

if I do

val json = parse("""
         { "name": "joe",
           "children": [
             {
               "name": "Mary",
               "age": 5
             },
             {
               "name": "Mazy",
               "age": 3
             }
           ]
         }
       """)

  val t =  json \\ "name " 

This would give me all the list of name instead of just give me parents name.

res1: org.json4s.JValue = JObject(List((name,JString(joe)), (name,JString(Mary)), (name,JString(Mazy))))

The issue names no source file, test, or entry point; it only provides a JSON example and a json4s query. Start by reproducing the query and checking the project’s query/operator documentation, with completion defined as a tested way to select only the root name.
