“Filed Under”…

I’d like to change the html output on each entry.
I have the following under each entry:
[code]
<div class="posted">
<?php the_category() ?> | <?php the_author() ?> | <?php the_time() ?> <?php edit_post_link(); ?>
<?php link_pages('
Pages: ', '
', 'number'); ?>
<?php comments_popup_link('Comments (0)', 'Comments (1)', 'Comments (%)'); ?>
</div>
[/code]
What’s coming up, is a list format around the category, which I don’t want. Which file do I have to edit, in order to change that? I went to the header file, but couldn’t find what I thought I’d be looking for. Admittedly it’s late, so I’ll stop for now. But I’d love any answers.
Thanks so much in advance.
