    If you are using Angular2+ following code will help

    You can use following syntax to get attribute value from html element

    //to retrieve html element

    const element = fixture.debugElement.nativeElement.querySelector('name of element'); // example a, h1, p

    //get attribute value from that element

      const attributeValue = element.attributeName // like textContent/href

    function onContentLoad() {
  var item = document.getElementById("id1");
  var x = item.dataset.x;
  var data = item.dataset.myData;

  var resX = document.getElementById("resX");
  var resData = document.getElementById("resData");

  resX.innerText = x;
  resData.innerText = data;

  console.log(x);
  console.log(data);
}
    <body onload="onContentLoad()">
  <div id="id1" data-x="a" data-my-data="b"></div>

  Read 'x':
  <label id="resX"></label>
  <br/>Read 'my-data':
  <label id="resData"></label>
</body>
