Problem with Google Maps Api JS

How do I create a link (a with href) in the markers that come from the database? Follow the code ...

    function initMap() { // Aqui começa a parte do mapa INICIA ELE
    //Cria uma variavel para receber o mapa
    var map = new google.maps.Map(document.getElementById('map'), {
        //Aqui é a definição de onde o mapa deve iniciar
      center: new google.maps.LatLng(-20.189540, -44.751045),
        //Aqui define o zoom inical do mapa
      zoom: 17
    });
    var infoWindow = new google.maps.InfoWindow({map :map});

    if(navigator.geolocation){
        navigator.geolocation.getCurrentPosition(function(position){
            var pos = {
                lat : position.coords.latitude,
                lng : position.coords.longitude

            };
            infoWindow.setPosition(pos);
            infoWindow.setContent("Estou aqui");
            map.setCenter(pos);

        }, function (){
            hendleLocationError(true, infoWindow, map.getCenter());
        });
    }
    // ---------- AQUI COMEÇA A PARTE QUE BUSCA OS PONTOS CADASTRADOS NO BANCO DE DADOS ----------   
      downloadUrl('resultado.php', function(data) {
        var xml = data.responseXML;
        var markers = xml.documentElement.getElementsByTagName('marker');
        Array.prototype.forEach.call(markers, function(markerElem) {
          var name = markerElem.getAttribute('name');
          var address = markerElem.getAttribute('address');
          var type = markerElem.getAttribute('type');
          var point = new google.maps.LatLng(
              parseFloat(markerElem.getAttribute('lat')),
              parseFloat(markerElem.getAttribute('lng')));

          var infowincontent = document.createElement('div');
          var strong = document.createElement('strong');
          strong.textContent = name
          infowincontent.appendChild(strong);
          infowincontent.appendChild(document.createElement('br'));

          var text = document.createElement('text');
          text.textContent = address
          infowincontent.appendChild(text);

          var icon = customLabel[type] || {};
          var marker = new google.maps.Marker({
            map: map,
            position: point,
            label: icon.label
          });
          marker.addListener('click', function() {
            infoWindow.setContent(infowincontent);
            infoWindow.open(map, marker);
          });
        });
      });

     // ---------- TERMINO DO NO BANCO DE DADOS ----------
    } // Fecha a funçao intMAp NAO APAGAR
