An almost better attempt (now I catch unapproved urls), but still
relying on generated html:

function MyMarkupFunc($pagename, $target) {
  $link = MakeLink($pagename, $target);
  preg_match("/.*class='([^']+)'.*href='([^']+)'.*/", $link, $m);
  if($m[1] == 'apprlink') return Keep($m[0]);
  $link = $m[2];

 # ...
}
