The <code><a class="el" href="classDOMNodeList.html" title="The DOMNodeList interface provides the abstraction of an ordered collection of nodes...">DOMNodeList</a></code> interface provides the abstraction of an ordered collection of nodes.
<p>
DOMNodeLists are created by <a class="el" href="classDOMDocument.html#4caab53f01e6489e2bc1cf9e96d748bd" title="Returns a DOMNodeList of all the DOMElement(s) with a given tag name in the order...">DOMDocument::getElementsByTagName()</a>, <a class="el" href="classDOMNode.html#28990e120a00edb3cd40cb92be962a5f" title="Gets a DOMNodeList that contains all children of this node.">DOMNode::getChildNodes()</a>,<p>
The items in the <code><a class="el" href="classDOMNodeList.html" title="The DOMNodeList interface provides the abstraction of an ordered collection of nodes...">DOMNodeList</a></code> are accessible via an integral index, starting from 0.<p>
DOMNodeLists are "live", in that any changes to the document tree are immediately reflected in any DOMNodeLists that may have been created for that tree. <hr><h2>Constructor &amp; Destructor Documentation</h2>
