Rules Admin UI Functions for rendering a rule. If a rule is viewed, it's passed to drupal_get_form so it is rendered with drupal_render().

Code

function theme_rules_operation($element) {
  if (count(element_children($element)) == 0 && !isset($element['#_root'])) {

    //no children, so drupal_render() won't render the element itself, so we do it ourself except for the condition root (AND)
    $element['#children'] = t('Empty');
    return theme('OR', $element);
  }

  //render the children and put the operation between them
  $content = array();
  foreach (element_children($element) as $key) {
    $content[] = drupal_render($element[$key]);
  }
  $print_op = theme('rules_logical_operation_label', drupal_strtolower($element['#label']), $element['#label']);
  return implode($print_op, $content);
}
