setInterval(function() { 
    downloadUrl("conection/cargar_tecnicos.php", function(data) {

        var xml = data.responseXML;
         markers = xml.documentElement.getElementsByTagName("marker");
         removeAllMarkers();
        for (var i = 0; i < markers.length; i++) {
              var name = markers[i].getAttribute("name");

},10000);
}
function removeAllMarkers(){// removes all markers from map
    for( var i = 0; i < marker.length; i++ ){
            marker[i].setMap(null);
}
}
