How to remove code from HTML string?

I have a variable that has this string:

<DIV><SPAN style="FONT-FAMILY: Tahoma; FONT-SIZE: 10pt">[If the confirmation is active the subscriber will receive this email after succesfully confirming. If not, this will be the first and only email he will receive.]</SPAN></DIV>
<p align=center>
    <input class=fieldbox10 type = 'button' name = 'button' value = 'Close' onclick = "window.close()">
</p>

How do开发者_开发技巧 I remove the below string without worrying about spaces via Javascript (or jQuery)?

<p align=center>
    <input class=fieldbox10 type = 'button' name = 'button' value = 'Close' onclick = "window.close()">
</p>

Maybe this?

$(html).remove('p');

If your var was myString you can do this:

var temp = $("<div />").append(myString);
temp.find('p:has(input[value=Close])').remove('p');
myString = temp.html();​
