Advanced json just need the record object block

Lets say I have the following JSON OBJECT

{
    "teamname": "Anaheim Ducks",
    "nickname": "Ducks",
    "SportTypes": {
      "-JZLOh7KtM78I5wAL6Ua": true
    },
    "locations": {
      "-JZLCFtpcuvsYxb5N1Cc": true
    },
    "countries": {
      "-JZG9IwEwKGqsExky7UT": true
    },
    "leagues": {
      "-JZLd1hXyyr9ehLwmmbc": true
    },
    "Divisions": {
      "-JZLh2UYKi5IvphLtX4I": true,
      "-JZLh2UaZbpcO7XixD1x": true
    }
  }

Select allOpen in new window

I want to loop thru it and pull the record chunks so if the loop pointer position is at 0 all the following JSON chunk will be stored in a variable.

{
    "teamname": "Anaheim Ducks",
    "nickname": "Ducks",
    "SportTypes": {
      "-JZLOh7KtM78I5wAL6Ua": true
    },
    "locations": {
      "-JZLCFtpcuvsYxb5N1Cc": true
    },
    "countries": {
      "-JZG9IwEwKGqsExky7UT": true
    },
    "leagues": {
      "-JZLd1hXyyr9ehLwmmbc": true
    },
    "Divisions": {
      "-JZLh2UYKi5IvphLtX4I": true,
      "-JZLh2UaZbpcO7XixD1x": true
    }
  }
