For example, I have <span id="convert">1</span> somewhere on my page.
Notice the "1", I want to covert "1" into let's say "John" every time the "1" is within a span tag with "convert" as the id.

I also want "2" to be converted to "Pete". And "3" to be converted to "Bob".

So if my html is:

<span id="convert">1</span>
<span id="convert">2</span>
<span id="convert">3</span>

my page reads:

John
Pete
Bob


Anyone know how to do this?
