<XML ID=MyXMLDocument>
<class>

-------------------------------------------------------------
The candidate has to write the code for the above giveb question in the textarea box, and since the code contains html tags , i have been facing problems in retrieveing the data from the textareabox in the exact manner has entered by the candidate.

Is there any solution to retrieve the exact code with the html tags.
