jquery selection method
<pre><code>   &lt;script&gt;
            $("*", document.body).each(function () {//is document.body a context?
                var parentTag = $(this).parent().get(0).tagName;
                //Above statement is only selecting the body tag why?

                $(this).prepend(document.createTextNode(parentTag + " &gt; "));
            });
    &lt;/script&gt;
  &lt;/body&gt;
&lt;/html&gt;       
</code></pre>

<p>Is there any reason for selecting only body tag in the above script?Also is document.body a context?since document.body is not quoted will it be a context?</p>
