<h2>Description</h2>
<div class="description">
<p>Objects implementing the <a href="Poco.XML.NamedNodeMap.html" title="class Poco::XML::NamedNodeMap">NamedNodeMap</a> interface are used to represent collections of nodes that can be accessed by name. Note that <a href="Poco.XML.NamedNodeMap.html" title="class Poco::XML::NamedNodeMap">NamedNodeMap</a> does not inherit from <a href="Poco.XML.NodeList.html" title="class Poco::XML::NodeList">NodeList</a>; NamedNodeMaps are not maintained in any particular order. Objects contained in an object implementing <a href="Poco.XML.NamedNodeMap.html" title="class Poco::XML::NamedNodeMap">NamedNodeMap</a> may also be accessed by an ordinal index, but this is simply to allow convenient enumeration of the contents of a <a href="Poco.XML.NamedNodeMap.html" title="class Poco::XML::NamedNodeMap">NamedNodeMap</a>, and does not imply that the DOM specifies an order to these Nodes. </p>
<p><a href="Poco.XML.NamedNodeMap.html" title="class Poco::XML::NamedNodeMap">NamedNodeMap</a> objects in the DOM are live. </p>
<p>A <a href="Poco.XML.NamedNodeMap.html" title="class Poco::XML::NamedNodeMap">NamedNodeMap</a> returned from a method must be released with a call to release() when no longer needed. </p>

This is seen as preferable to allowing nodes to be aliased. </p>
