This does work (fixed version of function):

function use2polygon($use,$polygon) {
    // get the xy coords
    $x = 0; $y = 0;
    if ($use->hasAttribute('x')) {
       $x = 0 + $use->getAttribute('x');
       }
    if ($use->hasAttribute('y')) {
       $y = 0 + $use->getAttribute('y');
       }
    // clone the polygon
    if ($polygon->hasAttribute('points')) {
$points = preg_replace('/\s+/',' ',$polygon->getAttribute('points'));
       $pointArray = explode(' ',$points);
       $sizeof = sizeof($pointArray);
       for ($i=0;$i<$sizeof;$i++) {
          $foo = explode(',',$pointArray[$i]);
          $foo[0] = $x + $foo[0];
          $foo[1] = $y + $foo[1];
          $pointArray[$i] = $foo[0] . ',' . $foo[1];
          }
       $points = implode(' ',$pointArray);
       $newPolygon = $polygon->cloneNode(true);
       $newPolygon->setAttribute('points',$points);
       $use->parentNode->replaceChild($newPolygon,$use);
       }
    }
