<hr><a name="_details"></a><h2>Detailed Description</h2>
By far the vast majority of objects (apart from text) that authors encounter when traversing a document are <code>DOM_Element</code> nodes.
<p>
Assume the following XML document:&lt;elementExample id="demo"&gt; &lt;subelement1/&gt; &lt;subelement2&gt;&lt;subsubelement/&gt;&lt;/subelement2&gt; &lt;/elementExample&gt;
<p>
When represented using DOM, the top node is an <code>DOM_Element</code> node for "elementExample", which contains two child <code>DOM_Element</code> nodes, one for "subelement1" and one for "subelement2". "subelement1" contains no child nodes.
<p>
Elements may have attributes associated with them; since the <code>DOM_Element</code> interface inherits from <code><a class="el" href="class_DOM_Node.html">DOM_Node</a></code>, the generic <code><a class="el" href="class_DOM_Node.html">DOM_Node</a></code> interface method <code>getAttributes</code> may be used to retrieve the set of all attributes for an element. There are methods on the <code>DOM_Element</code> interface to retrieve either an <code><a class="el" href="class_DOM_Attr.html">DOM_Attr</a></code> object by name or an attribute value by name. In XML, where an attribute value may contain entity references, an <code><a class="el" href="class_DOM_Attr.html">DOM_Attr</a></code> object should be retrieved to examine the possibly fairly complex sub-tree representing the attribute value. On the other hand, in HTML, where all attributes have simple string values, methods to directly access an attribute value can safely be used as a convenience.

This overloaded variant is provided for the sole purpose of setting a <a class="el" href="class_DOM_Node.html">DOM_Node</a> reference variable to zero.
