Delete all Subscriber from a Supression List

Question

I'm trying to remove all subscribers from a suppression list, I have been able to get one in particular to be deleted, but I have not been able to do it for all of them. How could it be done? Thanks in advance

    var req = api.retrieve("List", 
    ["ListName", "ID"],
    {
        Property: "ListName",
        SimpleOperator: "equals",
        Value: "MySuppressionList"
    }
);

var listId = req.Results[0].ID;

var res = api.updateItem("Subscriber", {
    SubscriberKey: "XXXXXXXXXX",
    EmailAddress: "XXXXXXXXXXX",
    Lists: [
        {
            ID: listId,
            Action: "delete"
        }
    ]
});

You need to use deleteItem function to remove a subscriber from the specified list, thus here is the script that will do the job -

<script runat = "server">
    Platform.Load("Core", "1");
    var api = new Script.Util.WSProxy();

    var req = api.retrieve("List", 
        ["ListName", "ID"],
        {
            Property: "ListName",
            SimpleOperator: "equals",
            Value: "xxx"
        }
    );
    var listId = req.Results[0].ID;

    var res = api.deleteItem("Subscriber", {
        SubscriberKey: "xxx",
        EmailAddress: "xxx",
        Lists: [
            {
                ID: listId
            }
        ]
    });
</script>
