Hi there JJJCR_FOX,

document.all is IE propriety code and this is it's definition...

A collection of elements nested within the current element.
A reference to document.all, for example, returns a collection (array)
of all element objects contained by the document, including elements
that may be deeply nested inside the document's first level of elements.
Here is an example...
Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"
   "http://www.w3.org/TR/html4/strict.dtd">
<html lang="en">
<head>

<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<meta name="language" content="english"> 
<meta http-equiv="Content-Style-Type" content="text/css">
<meta http-equiv="Content-Script-Type" content="text/javascript">

<title></title>

<style type="text/css"></style>

<script type="text/javascript">
if(window.addEventListener){
   window.addEventListener('load',init,false);
 }
else {
if(window.attachEvent) {
   window.attachEvent('onload',init);
  }
 }

function init() {
if(document.all){
for(c=0;c<document.all.length;c++){
   alert(document.all[c].tagName);
  }
 }
else {
  alert('document.all is not supported');
  }
 }
</script>

</head>
<body>

<ul>
 <li>list one</li>
 <li>list two</li>
 <li>list three</li>
 <li>list four</li>
</ul>
