<p>[0-9]*</p>

and a replace string of:

<h3>\1</h3>

where the "\1" will contain whatever was matched by the "[0-9]*".

Harry, I don't know what regex flavor you are using, but all the engines that I know of require parentheses for capture groups.

So like this:

<p>([0-9]*)</p>

And then:

<h3>\1</h3>

For what Zelda wants, I'd use this:

<p>(\d+)</p>

With this:

<h3>\1</h3>
