Remove Textnode After It Is Created From The Array

I have created an array that holds three textmessages, how can I
remove the created textNode and feed the next message in line? Is
there also an issue with cleaning any whitespace too?

A code snippet:
----------------------

var altTextBanners = new Array(
"myText1",
"myText2",
"myText3");

altTextBanners.currentIndex = -1;

function initRotate() {

if (!document.getElementById) return;

altTextBanners.currentIndex++;

var text = document.createTextNode(altTextBanners[altTextBanners.currentIndex]);
var message = document.getElementById("message");
message.appendChild(text);
// how to remove the created TextNode and get the next one in the array
// ... ??
}

HTML

<span id="message"></span>
