<div class="descr">
<h2>Detailed Description</h2>
<p>The QDomNodeList class is a list of <a href="qdomnode.html">QDomNode</a> objects.</p>
<p>Lists can be obtained by <a href="qdomdocument.html#elementsByTagName">QDomDocument::elementsByTagName</a>() and <a href="qdomnode.html#childNodes">QDomNode::childNodes</a>(). The Document Object Model (DOM) requires these lists to be "live": whenever you change the underlying document, the contents of the list will get updated.</p>
<p>You can get a particular node from the list with <a href="qdomnodelist.html#item">item</a>(). The number of items in the list is returned by <a href="qdomnodelist.html#length">length</a>().</p>
<p>For further information about the Document Object Model see <a href="http://www.w3.org/TR/REC-DOM-Level-1/">Level 1</a> and <a href="http://www.w3.org/TR/DOM-Level-2-Core/">Level 2 Core</a>. For a more general introduction of the DOM implementation see the <a href="qdomdocument.html">QDomDocument</a> documentation.</p>
