i modified the code for use on my site so that the tags are clickable links. i did this by adding the following directly after the } else { statement within the startElement function:
$deltags = explode(" ", $attrs['TAG']);
foreach($deltags as &$delicioustag)
$delicioustag = '
'">' . $delicioustag . '';
$deltags = implode(" ", $deltags);
Obviously replace “jark” with your own username if you to make the links clickable for your profile.
Thought someone might find that useful as I find this script, in and of itself, invaluable.
