$postedValue Problem

Hi,
i have look a replacebyclass sample and try to edit it. I need to save into a .txt file the $postedValue value, but i need the "real html code".

I have read this: http://docs.cksource.com/CKEditor_3.x/D ... Formatting but i don't understand where i need to put the code.

The problem is this, the $postedvalue contain this:

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
   <title>Sample - CKEditor</title>
   <meta http-equiv="content-type" content="text/html; charset=utf-8" />
   <link type="text/css" rel="stylesheet" href="../sample.css" />
</head>
<body>
      <tr>
         <th style="vertical-align: top">editor1</th>

         <td><pre>&lt;p&gt;
   fdfgdfgfgdf&lt;/p&gt;
&lt;p&gt;
   &amp;nbsp;&lt;/p&gt;
&lt;p style=&quot;text-align: center;&quot;&gt;
   sadsadsadassd&lt;/p&gt;

</pre></td>
      </tr>
