    See Array.prototype.splice() for example,

    function MyArray()
{
    var myArray = ["One", "Two", "Three", "", "Five"];
    for (var i = 0; i < myArray.length; i++) {
        if (myArray[i] === "") {
            myArray.splice(i, 1);
            break;
        }
    }  

    for (var i = 0; i < myArray.length; i++) {
        Log.Message(myArray[i]);
    }
}

    Hi, thank you very much! To make it works I had to do little modifications but it works correctly

    var Devices_List = pageParameters01.FindAll("columnIndex", "3", 15, true).toArray()
    for (var i = 0; i < Devices_List.length; i++) {
    if (Devices_List[i].contentText == "") {
    Devices_List.splice(i, 1);
    break;
    }
    }

    for (var i = 0; i < Devices_List.length; i++) {
    Log.Message(Devices_List[i].contentText);
    }
