<h2>Description</h2>
<div class="description">
<p>The <a href="Poco.XML.NodeList.html" title="class Poco::XML::NodeList">NodeList</a> interface provides the abstraction of an ordered collection of nodes, without defining or constraining how this collection is implemented. </p>
<p>The items in the <a href="Poco.XML.NodeList.html" title="class Poco::XML::NodeList">NodeList</a> are accessible via an integral index,  starting from 0. </p>
<p>A <a href="Poco.XML.NodeList.html" title="class Poco::XML::NodeList">NodeList</a> returned from a method must be released with a call to  release() when no longer needed. </p>
