Hai,
This problem is common in web application, that to when we are handling raw HTML. So to skip html tags inside the textarea, textbox fields usually we put like this

<textarea ESCAPE=HTML>some text</textarea>
<input type="text" ESCAPE=HTML>some text</input>

But i am not sure this will help u to solve ur problem. But usually we do this to escape html, in web application.
Kindly excuse if i am wrong any where...
I want to share the idea..
