<h2>Definition and Usage</h2>
<p>The setAttribute() method adds a new attribute.</p>
<p>If an attribute with that name already exists in the element, its value is
changed to be that of the value parameter</p>
<h2>Syntax</h2>
<table class="ex" cellspacing="0" border="1" width="100%" id="table36">
<tr>
<td>
<pre>elementNode.setAttribute(name,value)</pre>
</td>
</tr>
</table>
<br />

<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</h2>
<p>The following code fragment loads "<a target="_blank" href="books.xml">books.xml</a>"
into xmlDoc using <a href="dom_loadxmldoc.asp">
loadXMLDoc()</a> and adds an "edition" attribute to all <book>
elements:</p>
<table class="ex" id="table43" border="1" cellspacing="0" width="100%">
<tr>
<td>
<pre>xmlDoc=loadXMLDoc("books.xml");</pre>
<pre>x=xmlDoc.getElementsByTagName("book");</pre>
<pre>for(i=0;i<x.length;i++)
{
x.item(i).setAttribute("edition","first");
}</pre>
<pre>//Output book title and edition value
x=xmlDoc.getElementsByTagName("title");
for (i=0;i<x.length;i++)
{
document.write(x[i].childNodes[0].nodeValue);
document.write(" - Edition: ");
document.write(x[i].parentNode.getAttribute('edition'));
document.write("<br />");
}</pre>
</td>
</tr>
</table>
<p>Output:</p>
<table class="ex" id="table44" border="1" cellspacing="0" width="100%">
<tr>
<td>
<pre>Everyday Italian - Edition: FIRST
Harry Potter - Edition: FIRST
XQuery Kick Start - Edition: FIRST
