javascripts regular expression to keep span tag and remove other

Question

Can anyone provide me the regular expression in JavaScript for

Input:

<table><tr><td>hello<td/> <span class='xyz'>Hi all </span></tr></table>

Output:

hello<span class='xyz'>Hi all</span>

I can successfully use the following expression in Java but I don't know the equivalent regular expression in JavaScript.

String newValue = input.replaceAll("<(?!\\/?span)[^>]+>", "");

if i use following expression in js

input.replace(/<(?!/?span)[^>]+>/g, "");

i am getting output as

 hello Hi all</span>

but i want

hello<span class='xyz'>Hi all</span>

Don't parse HTML with regexes! http://stackoverflow.com/questions/1732348/regex-match-open-tags-except-xhtml-self-contained-tags/1732454#1732454 — Paul Draper, Oct 31 '13 at 05:54
*"I don't know the equivalent regular expression in JavaScript"* You could use the exact same expression. — Felix Kling, Oct 31 '13 at 06:10
