You can probably do this using regular expression's and a replace()
call, using the buffer and non-greedy operators (as one option), but
rather than write such a regex for you it would be best if you could
allow an actual HTML parser (such as a browser) to do the work for you.

If you don't care about browser compatibility (you are using this just
for yourself), you could use innerHTML and innerText in IE. For
example, add the HTML to an object in the document using innerHTML or
insertAdjacentH TML, and then read it back using innerText.

Here's an example:

<body>

<div id="divContaine r"></div>

<script>
var sHTML = "<div>a<div >b</div></div>";
divContainer.in nerHTML = sHTML;
alert(divContai ner.innerText);
</script>

</body>

I assume you're trying to remove all tags except <p></p>
Unless someone knows another way, you can do it in two separate operations.
The first removes all tags except <p></p> but does not remove parameters within the opening <p> tag.

str=str.replace (/<(?!\s*p\s*|\w> |\s*\/\s*p\s*>)[^>]+>/gi, "")

str=str.replace (/<\s*p[^>]+>/gi, "<p>");

This isn't a universal solution, but on recent browsers it works on your example text.

The first operation removes all tags except <p></p>; the second removes parameters within the opening <p> tag.
It won't handle nested <> characters.
I have avoided the use of lookahead assertions.

str=str.replace (/<\s*([a-oq-z]|p\w|\!)[^>]*>|<\s*\/\s*([a-oq-z]|p\w)[^>]*>/gi, "");

str=str.replace (/<\s*p[^>]+>/gi, "<p>");
