<code><aclass="el"href="classxercesc_1_1DOMNamedNodeMap.html">DOMNamedNodeMap</a></code>s are used to represent collections of nodes that can be accessed by name.
<p>
Note that <code><aclass="el"href="classxercesc_1_1DOMNamedNodeMap.html">DOMNamedNodeMap</a></code> does not inherit from <code><aclass="el"href="classxercesc_1_1DOMNodeList.html">DOMNodeList</a></code>; <code><aclass="el"href="classxercesc_1_1DOMNamedNodeMap.html">DOMNamedNodeMap</a></code>s are not maintained in any particular order. Nodes contained in a <code><aclass="el"href="classxercesc_1_1DOMNamedNodeMap.html">DOMNamedNodeMap</a></code> may also be accessed by an ordinal index, but this is simply to allow convenient enumeration of the contents, and does not imply that the DOM specifies an order to these Nodes.<p>
<dlcompact><dt><b>Returns:</b></dt><dd>A <code><aclass="el"href="classxercesc_1_1DOMNode.html">DOMNode</a></code> (of any type) with the specified <code>nodeName</code>, or <code>null</code> if it does not identify any node in the map. </dd></dl>
<dlcompact><dt><b>Returns:</b></dt><dd>A <code><aclass="el"href="classxercesc_1_1DOMNode.html">DOMNode</a></code> (of any type) with the specified local name and namespace URI, or <code>null</code> if they do not identify any node in the map. </dd></dl>
If <code>index</code> is greater than or equal to the number of nodes in the map, this returns <code>null</code>. <dlcompact><dt><b>Parameters:</b></dt><dd>

As the <code>nodeName</code> attribute is used to derive the name which the node must be stored under, multiple nodes of certain types (those that have a "special" string value) cannot be stored as the names would clash.
