ParagraphFormat() ? where art thou..

Interesting night for me, as I’ve spent the last 4 hours fumbling around in the Google dark trying to find a way to take “comments” for the team.silverlight blog, sanitize them but preserve their natural format in which the user typed them.

In that for example, I like to sign my signature in most comments on blogs like this:

-
Scott Barnes
Rich Platforms Product Manager
Microsoft.

3 Lines basically, but to do this in most of the libraries I've seen, they always end up like this:

- Scott Barnes Rich Platforms Product Manager Microsoft.

The only way i can preserve the said format, is to use <pre> tags and via CSS make them look more natural.

The downside, is I then sacrifice basic html which is one feature I want to implement.

Any magical RegEx formulas out there than can handle both shift+linefeed as well as preserve double space line feeds with <p></p> tags I’m all ears.

As the intended format of a comment should end up like this:

 start

 <p> 
  Your comment goes here 
</p> 
<p> 
    -<br /> 
  Scott Barnes</br> 
    Rich Platforms Product Manager </br> 
 Microsoft</br> 
</p>
