<h1>XML DOM Clone Nodes</h1>

<h2>Examples
</h2>
<p>The examples below use the XML file
<a target="_blank" href="books.xml">books.xml</a>. <br />
A function, <a href="dom_loadxmldoc.asp">loadXMLDoc()</a>, in an external JavaScript is used to load the XML file.</p>
<p><a target="_blank" href="tryit.asp@filename=try_dom_clonenode">Copy a node
and append it to an existing node</a><br />
This example uses cloneNode() to copy a node and append it to
the root node of the XML document</p>
<hr />
<h2>Copy a Node</h2>
<p>The cloneNode() method creates a copy of a specified node.</p>
<p>The cloneNode() method has a parameter (true or false). This
parameter indicates if the cloned node should include all attributes and child
nodes of the original node.</p>
<p>The following code fragment copies the first <book> node and appends it
to the root node of the document:</p>
<table width="100%" border="1" class="ex" cellspacing="0" id="table21">
<tr><td>
<pre>xmlDoc=loadXMLDoc("books.xml");</pre>
<pre>oldNode=xmlDoc.getElementsByTagName('book')[0];
newNode=oldNode.cloneNode(true);
xmlDoc.documentElement.appendChild(newNode);
//Output all titles
y=xmlDoc.getElementsByTagName("title");
for (i=0;i<y.length;i++)
{
document.write(y[i].childNodes[0].nodeValue);
document.write("<br />");
}</pre>
</td></tr>
</table>
<p>Output:</p>
<table width="100%" border="1" class="ex" cellspacing="0" id="table22">
<tr><td>
<pre>Everyday Italian
Harry Potter
XQuery Kick Start
Learning XML
Everyday Italian</pre>
</td></tr>
</table>
<p>Example explained:</p>
<ol>
<li>Load "<a target="_blank" href="books.xml">books.xml</a>"
into xmlDoc using <a href="dom_loadxmldoc.asp">loadXMLDoc()</a> </li>
<li>Get the node to copy</li>
<li>Copy the node into "newNode" using the cloneNode method</li>
<li>Append the new node to the the root node of the XML document</li>
<li>Output all titles for all books in the document</li>
</ol>
<p><a target="_blank" href="tryit.asp@filename=try_dom_clonenode">Try
it yourself</a><br />
