Open link in new blank page?

What I must modify for open all link's from principal link, secondary link, rss link and ... other link's in a new blank window ?

ok
how can I change for primary and secondaru links

back again

I vahe this code:

 <td rowspan="2" id="logo"> <?php if ($logo) { ?>      <a href="./" title="Home" <b>target="_blank"</b>><img src="<?php print $lo
go ?>" alt="Home" /></a>      <?php } ?></td>

I put in this code target="_blank"

Where can I put the same code in this code:

<td colspan="2" id="prime-top"> <div id="primary-tabs">
  <?php if (count($primary_links)) : ?>
      <ul><?php foreach ($primary_links as $link): ?>
          <?php
          static $primary_link_id;
          $primary_link_id += 1;
        ?>
        <?php $class = ""; ?>
        <?php if ( stristr($link, 'active') ) : ?>
        <?php $class = 'class="current"'; ?>
        <?php endif; ?>
        <li <?php print $class?> id="primary-link-<?php print $primary_link_id; ?>" > <?php print $link?> </li>
          <?php endforeach; ?>
        </ul>
  <?php endif; ?>
    </div></td>
