How can i get to my Children Terms? (building a sub nav bar)

Hi All,

Currently i am able to print out a list of my primary_links (taxonomy terms) by doing this

<div id="nav-primary" class="clearfix">

<?php if (is_array($primary_links)) : ?>
<ul id="maintab">

<?php foreach ($primary_links as $link): ?>
<li><?php       
        $href = $link['href'] == "<front>" ? base_path() : base_path() . drupal_get_path_alias($link['href']);
        print "<a href='" . $href . "' onmouseover='showTab( " . $link['title'] .")'>" . $link['title'] . "</a>";           
        ?></li>
<?php endforeach; ?>
</ul>
<?php endif; ?>

That works beautifully....

My trouble is that i would also like to do print out some of the children of these terms but i cant seem to figure out how to do this.

My initial thought was do something like foreach of the primary links do a for each on it's children but it looks like ive only got access to:

[attributes] => Array
(
[title] =>
)

[href] => taxonomy/term/8
[title] => Title

Do i have any options? thanks so much for your time.
