Regular expression : parse html to certain html

Question

We having a HTML content like

<em></ em > 
<font style="text-align:justify;">aaaaaaaaaaa</font>
<img src="abc.jpg"/>
<iframe src="somelink.com"> 
</iframe>
<br>
<br/>

We want to change all HTML Tags to 

but do not change the <img/> and   tag, some   tags may display  

so, the following is our expected result:

<p></p> 
<p>aaaaaaaaaaa</p>
<img src="abc.jpg"/>
<p> 
</p>
<br>
<br/>

My regular expression like (in C#):

String result = Regex.Replace(content, @"<[^/b>]*>", "<p>");
result = Regex.Replace(result, @"</[^>]*>", "</p>");

but it can't skip the certain tags, please help me, thanks !

Don't use regex for HTML changes, use jQuery, or some similar HTML parsing library/functions. Using regular expressions to parse HTML: why not? — Tushar

@Tushar Okay - but what library supports a replace operation of any kind of tag to a specified tag? — Sebastian Schumann

You can use this:

and replace with:

<${close}p>

It has a more character '?' in the end of <${close}p>?
