PHP - Colour XML Code

Hi,

Is there any scripts / functions out there that will colour code XML when its inserted or comes from a database / strings?

Eg:


//Page Title
$sPageTitle = "LaszloCode";
//Include Header
include("include/header.php");

//Similar to what is happening here, it has coloured the 'PHP'

Similar to what is happening here, it has coloured the ‘PHP’

Cheers,
Ryan
