<h1>XML DOM setAttributeNS() Method</h1><hr />
<a href="dom_element.asp"><img class="navup" src="../images/up.gif" alt="Element Object Reference" border="0" /> Complete Element Object Reference</a>

<h2>Definition and Usage</h2>
<p>The setAttributeNS() method adds a new attribute (with a namespace).</p>
<p>If an attribute with that name or namespace already exists in the element,
its value is changed to be that of the prefix and value parameter</p>
<h2>Syntax</h2>
<table class="ex" cellspacing="0" border="1" width="100%" id="table36">
<tr>
<td>
<pre>elementNode.setAttributeNS(name,value)</pre>
</td>
</tr>
</table>
<br />
<table class="ex" cellspacing="0" border="1" width="100%" cellpadding="3" id="table37">
<tr>
<th align="left" valign="top" width="20%">Parameter</th>
<th align="left" valign="top" width="80%">Description</th>
</tr>
<tr>
<td valign="top">ns</td>
<td valign="top">Required. Specifies the namespace URI of the attribute to set</td>
</tr>
<tr>
<td valign="top">name</td>
<td valign="top">Required. Specifies the name of the attribute to set</td>
</tr>
<tr>
<td valign="top">value</td>
<td valign="top">Required. Specifies the value of the attribute to set</td>
</tr>
</table>
<hr />
<h2>Example 1</h2>
<p>The following code fragment loads "<a target="_blank" href="books_ns.xml">books_ns.xml</a>"
into xmlDoc using <a href="dom_loadxmldoc.asp">
loadXMLDoc()</a> and adds an "edition" attribute to the first <book>
element:</p>
<table class="ex" id="table47" border="1" cellspacing="0" width="100%">
<tr>
<td>
<pre>xmlDoc=loadXMLDoc("books_ns.xml");</pre>
<pre>x=xmlDoc.getElementsByTagName("book")[0];
ns="http://www.w3schools.com/edition/";</pre>
<pre>x.setAttributeNS(ns,"edition","first");</pre>
<pre>document.write(x.getAttributeNS(ns,"edition"));</pre>
</td>
</tr>
</table>
<p>Output:</p>
<table class="ex" id="table48" border="1" cellspacing="0" width="100%">
<tr>
<td>
<pre>first</pre>
</td>
</tr>
</table>
<br />
<hr />
<h2>Example 2</h2>
<p>The following code fragment loads "<a target="_blank" href="books_ns.xml">books_ns.xml</a>"
into xmlDoc using <a href="dom_loadxmldoc.asp">
loadXMLDoc()</a> and changes the "lang" value of the first <title> element:</p>
