Get post sulg and use it for a variable in multiple loops… ?

Ok… I don’t know if I can do what I wanna do! ??

When I’m on my single.php, meaning I’m reading a particular post, I would like to get the post-slug of the post i’m reading and use it as a variable in query_posts later in the page.

I wanna use the post-slug of a particular posts as a tag in other posts, wich are relative to this post…

Example :

I’m reading the post XYZ, with the post-slug XYZ. So I have a first loop to display it:

<?php while (have_posts()) : the_post(); ?>
Display the post's stuff
<?php endwhile; ?>

Then,on this same page, after this first loop, I want to put other loops to display all posts using the post-slug of the first post as a tag…

<?php
query_posts(array(
'tag_slug__and'=>array('the-slug-of-the-post-looped-above '),
) );
?>

Or

<?php query_posts('tag=the-slug-of-the-post-looped-above'); ?>

Don’t know if I’m clear enough… ?? It is possible ?

Thanks.
