<p>You can use <code>.childNodes</code> to retrieve all children instead of <code>.getElementsByTagName('*')</code> which will only return child elements.</p>
<p>Here is a function to retrieve all descendants of a DOM node:</p>
<pre><code>function getDescendantNodes(node)
{
var ret = [];
if( node )
{
var childNodes = node.childNodes;
for( var i = 0, l = childNodes.length; i < l; ++i )
{
var childNode = childNodes[i];
ret.push(childNode);
ret = ret.concat(getDescendantNodes(childNode));
}
}
return ret;
}
</code></pre>
<p>Usage:</p>
<pre><code>getDescendantNodes(document.getElementById("foo"));
</code></pre>
