Textarea and formatting

I have a textarea that generates dinamically a text.
In the textarea there's a formatted text, such as:

<h1>title</h1>
<p>bla bla bla</p>

Code (markup):

The problem is that the page is not validated, because the tag p and h1 are not allowed within a textarea.

Suggestions about solving this problem?

 

You should use wyswyg editors like FCK editor to over come the issue.
Such editors automatically convert formatting into html and user will love to use it.

 

Here is a list of WYSIWYG editors.

Hope that helps.

 

I think you gave me a solution
I changed the tag from

<p>

Code (markup):

to <p> and now I have alla pages validated
