Here's some code that should get you a path to your object, not sure how super safe it is:

function getPath(obj, val, path) {
   path = path || "";
   var fullpath = "";
   for (var b in obj) {
      if (obj[b] === val) {
         return (path + "/" + b);
      }
      else if (typeof obj[b] === "object") {
         fullpath = getPath(obj[b], val, path + "/" + b) || fullpath;
      }
   }
   return fullpath;
}

Where testObj is the object in your example:

console.log(getPath(testObj, '20'));      // Prints: /part3/2/qty
console.log(getPath(testObj, "[value]")); // Prints: /part3/1/name
