"a.ChildNodes" should be "a.childNodes"
(mind the case...)

onload=SetText; ......

This code working for me:
<html>
<body>
<div id ="demo">
<p>some text</p>
<p>some other text</p>
</div>
<script>
function setText(){
var a = document.getElementById("demo");
var b = a.querySelectorAll("*");
b[0].innerHTML = "new text";
}
//calling the function with setTimeout to make sure the HTML is loaded
setText ();
</script>
</body>
</html>

use "a.querySelectorAll("*")" instead of "a.childNodes"
+ 3
use the .children property like a.children

You have 5 childNode there.
b[1].innerHTML would update first paragraph.

use this one its working I tested it
b[1].innerHTML="new text";
windows.onload= function() {
setText();
};

Don't use timeout to check DOM loading,
use window.online
Just add
window.onload = setText;

I realized that, changed it still does not work.

change the 0 to 1 index

windows.onload= function() {
setText();
};
