Strip the_meta() html

I am using the_meta() for custom fields. How can I alter the output html to my preferred result?

Code
<?php echo the_meta(); ?>

Result

<ul class='post-meta'>
<li><span class='post-meta-key'>Client:</span> Personal</li>
</ul>

Preferred Result

<ul class="info">
<li class="info-type"><span>Client:</span> Personal</li>
</ul>
