Code

<?php
function node_view($node, $teaser = FALSE, $page = FALSE, $links = TRUE) {
  $node = (object)$node;

  // Remove the delimiter (if any) that separates the teaser from the body.
  // TODO: this strips legitimate uses of '<!--break-->' also.
  $node->body = str_replace('<!--break-->', '', $node->body);

  if ($node->log != '' && !$teaser && $node->moderate) {
    $node->body .= '<div class="log"><div class="title">'. t('Log') .':</div>'. filter_xss($node->log) .'</div>';
  }

  // The 'view' hook can be implemented to overwrite the default function
  // to display nodes.
  if (node_hook($node, 'view')) {
    node_invoke($node, 'view', $teaser, $page);
  }
  else {
    $node = node_prepare($node, $teaser);

  if ($links) {
    $node->links = module_invoke_all('link', 'node', $node, !$page);
