tinymce "codesample" plugin executes HTML tag

I am using codesample plugin of tinymce which is mentioned here in my custom portal.

Everything works fine, until, I have to "re-edit" the data stored in database.

When i go to edit, all data stored in database within

<pre><code>&lt;html&gt; &lt;p&gt;Text&lt;/p&gt; &lt;/html&gt; </code></pre>

is stripped and shown as only

<pre><code>Text </code></pre>

when viewed from "Tools > Source"

I am already using "htmlentities" in my textarea like :-

<textarea><?php echo htmlentities($content); ?></textarea>

It still strips all html tag used inside the tag created by

1. When adding data for the first time everything works fine.
2. Problem is only when i go to edit page. Tinymce strips only HTML code from
plugin. Rest all code that has been added using codesample like "css,python,php" etc., are displayed in editor.

Ok, after lots of research, I found that it is an encoding issue. One need to encode each entity like :- < , > to &lt; , &gt; Alongwith & character inside <code> tag to &amp;. Thus, Code like below :-

<pre><code>&lt;html&gt; &lt;p&gt;Text&lt;/p&gt; &lt;/html&gt; </code></pre>

should be like

&lt;pre&gt;&lt;code&gt;&amp;lt;html&amp;gt; &amp;lt;p&amp;gt;Text&amp;lt;/p&amp;gt; &amp;lt;/html&amp;gt; &lt;/code&gt;&lt;/pre&gt;

So, for all users who are finding solution. This is the solution.

Remember, & inside <code> &amp;lt; </code> tag should only be converted to &amp; . Notice &lt; inside <code> tag is &amp;lt;
