<h2>Definition and Usage</h2>
<p>The replaceData() method replaces data in a comment node.</p>
<h2>Syntax</h2>
<table class="ex" cellspacing="0" border="1" width="100%" id="table36">
<tr>
<td>
<pre>commentNode.replaceData(start,length,string)</pre>
</td>
</tr>
</table>

<tr>
<th align="left" valign="top" width="20%">Parameter</th>
<th align="left" valign="top" width="80%">Description</th>
</tr>
<tr>
<td valign="top">start</td>
<td valign="top">Required. Specifies where to begin replacing characters.
Start value starts at zero</td>

<tr>
<td valign="top">length</td>
<td valign="top">Required. Specifies how many characters to replace</td>
</tr>
<tr>
<td valign="top">string</td>
<td valign="top">Required. Specifies the string to insert</td>
</tr>
</table>
<br />
<hr />
<h2>Example</h2>
<p>The following code fragment loads "<a target="_blank" href="books_comment.xml">books_comment.xml</a>"
into xmlDoc using <a href="dom_loadxmldoc.asp">
loadXMLDoc()</a> and replace "Simple" with "Easy" in the
comment node of the first <book> element:</p>
<table class="ex" id="table41" border="1" cellspacing="0" width="100%">
<tr>
<td>
<pre>xmlDoc=loadXMLDoc("books_comment.xml");</pre>
<pre>x=xmlDoc.getElementsByTagName("book")[0].childNodes;</pre>
<pre>for (i=0;i<x.length;i++)
{
if (x[i].nodeType==8)
{
//Process only comment nodes
x[i].replaceData(4,6,"Easy");
document.write(x[i].data);
document.write("<br />");
}
}</pre>
</td>
</tr>
</table>
<p>Output:</p>
<table class="ex" id="table42" border="1" cellspacing="0" width="100%">
<tr>
<td>
<pre>125 Easy and Delicious Recipes (Hardcover)</pre>
</td>
</tr>
</table>
<p>In the example above we use a loop and an if-test to make sure we only
process comment nodes. A comment node has a node type of 8.</p>
