get value of object key and parent javascript and create a new object

I have an object that looks like the following:

const testObject = {
  "NameA": {
    "Name": {
      "_text": "Peter"
    }
  },
  "AgeA": {
    "_comment": "line=2",
    "age": {
      "_text": "21"
    }
  },
  "Birth": {
    "_comment": "line=3",
    "Birthday": {
      "DateTimeSignUTCOffset": {
        "Date": {
          "_text": "191201"
        },
        "Time": {
          "_text": "1123"
        },
      },
      "Test": {
        "Code": {
          "_text": "1234"
        }
      },
    }
  }
}

I am trying to find any key with the key _text and get the corresponding value and the parent key.

i.e.

const result = { 
    "Name": "Peter",
    "age": "21",
    "Date": "191201",
    "Time": "1123",
    "Code": "1234"
};

I have tried the following by looping through the object but am unable to figure it out.

const result = {};

const find_items = (object) => {
  console.log(Object.keys(object));
  Object.keys(object).map((item) => {
    console.log(object[item]);
    if(object[item] !== '_text') {
      find_items(object[item])
    } else {
      console.log(item)
    }
  });
};

find_items(testObject);

console.log(result);

Can someone could point me in the right direction?

Answer

You could take a recursive approach and check for object and if _text property exist take the value with the outer key or get the entries from the recursive call with the object.

At the end build an object from all entries.

const
    flatEntries = object => Object
        .entries(object)
        .flatMap(([k, v]) => {
            if (v && typeof v === 'object') return '_text' in v
                ? [[k, v._text]]
                : flatEntries(v);
            return [];        
        });
    testObject = { NameA: { Name: { _text: "Peter" } }, AgeA: { _comment: "line=2", age: { _text: "21" } }, Birth: { _comment: "line=3", Birthday: { DateTimeSignUTCOffset: { Date: { _text: "191201" }, Time: { _text: "1123" } }, Test: { Code: { _text: "1234" } } } } },
    result = Object.fromEntries(flatEntries(testObject));

console.log(result);
