I'm not sure how to word what I want.
This is what I have:
		<ul id="dock">
				<?php
					$dock = new WP_Query();
					$dock->query( 'showposts=5' );
					while( $dock->have_posts() ) : $dock->the_post();
				?>
				<li>
					<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>">
					<img src="<?php bloginfo( 'template_directory' ); ?>/imgsize.php?w=69&h=54&img=<?php echo get_post_meta( $post->ID, "image_value", true ); ?>" alt="<?php the_title(); ?>" />
					</a>
					<span><?php the_title(); ?></span>
				</li>
				<?php
					endwhile;
				?>
			</ul>
Which gives me this for output:
			<ul id="dock">
				<li>
					<a href="#"....>
					<img src="#".... />
					</a>
					<span>Post Title</span>
				</li>
				<li>
					<a href="#"....>
					<img src="#".... />
					</a>
					<span>Post Title</span>
				</li>
<li>
					<a href="#"....>
					<img src="#".... />
					</a>
					<span>Post Title</span>
				</li>
<li>
					<a href="#"....>
					<img src="#".... />
					</a>
					<span>Post Title</span>
				</li>
<li>
					<a href="#"....>
					<img src="#".... />
					</a>
					<span>Post Title</span>
				</li>
							</ul>
as expected.
ALL I WANT is for the output to add a "pre-defined" id to each <li> tag.
IE: 
<li id="positionA"><a href="#"><img src="#"><span>SPAN</span></li>
<li id="positionB"><a href="#"><img src="#"><span>SPAN</span></li>
<li id="positionC"><a href="#"><img src="#"><span>SPAN</span></li>
<li id="positionD"><a href="#"><img src="#"><span>SPAN</span></li>
<li id="positionE"><a href="#"><img src="#"><span>SPAN</span></li>
The most recent 5 posts will always be called, and the most recent post must always be "positionA," while the 5th most recent post must always be "positionE."
Thanks in advance.

Lew Ayotte answers:
								In your wordpress loop do something like this:
<?php if (have_posts()) : ?>
<?php while(have_posts()) : the_post(); ?>
<?php 
$i = 1;
if ($i <= 5) { 
?>
<li id="position<?php echo $i; ?>"><a href="#"><img src="#"><span>SPAN</span></li>
<?php
$i++;
}
//other stuff 
<?php endwhile; ?>
<?php endif; ?>
