Currently I have:

this.html(this.html().replace(/<\/?([i-z]+)[^>]*>/gi, function(match, tag) { 
            return (tag === 'p') ? match : '<p>';
            return (tag === '/p') ? match : '</p>';
            return (tag === 'script') ? match : 'script';
            return (tag === '/script') ? match : '/script';
        }));

However, the <p> and <script> tags are still being removed, what am I doing wrong?

    Am pretty sure of this now, the regex doesnt work for closing tags, and only looking for i-z isnt catching the full tag.

    Try the regex of:

    /<\(/?[a-z]+)[^>]*>/gi

    something odd happens with the code though when trying to return ‘<script>’ when matching script so in these cases maybe return match

    Andy E’s head’s suggestion of changing the if statement structure I think helps too, the main thing is the

        else 
        return match;

    or even do this as a default instead of specifically looking for p and script tags, it will return the match value of the matched tag if no if statement is met.

    Code I wrote for testing:

    <!DOCTYPE HTML>
<html>
<body>
<div id="manipulate">
<p>Hello</p>
<script type="text/ecmascript">
// test
</script>
</div>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/ecmascript"></script>
<script type="text/ecmascript">
$(document).ready(function(){
alert("start");
$("#manipulate").html($("#manipulate").html().replace(/<\/?([a-z]+)[^>]*>/gi, function(match, tag) { 
            alert(tag);
            alert(match);
        if (tag === 'p') 
            return '<p>';
        else if (tag === '/p')
            return '</p>';
        else if (tag === 'script') 
            return match;
        else if (tag === '/script') 
            return match;
        else 
            return match;
        }));
});
</script>
</body>
</html>
