20分求助PHP循环问题！

这段代码运行正常，但是 <div class="body_fenlei_beijing"></div> 这个标签一直无限循环！各位大神帮忙看看是不是代码写错了！
<?php get_header(); ?>
<div id="container">
	<div id="main">
        <?php if ( function_exists('show_nivo_slider') ) { show_nivo_slider(); } ?>
    	<?php if (have_posts()) : while (have_posts()) : the_post(); ?>	
 <?php
  // 得到所有分类列表
  $categories = get_categories();
 
  // 循环所有分类
  foreach ($categories as $cat) {
 
    // 得到分类ID
    $catid = $cat->cat_ID;
 
    // 得到分类下10篇最新文章
	query_posts("showposts=10&cat=$catid"); ?>
<div class="body_fenlei_beijing">
  <div class="body_fenlei_kongbai"></div>
      
      <!– 输出分类标题及链接 –>
      <div class="body_fenlei_title">
          <h4><a href=”<?php echo get_category_link($catid);?>”
          title=”<?php echo strip_tags(category_description($catid)); ?>”>
          <?php single_cat_title(); ?>
          </a></h4>
      </div>
    
    <!– 输出10篇最新文章的标题及链接 –>
  <div class="body_fenlei_link">
        <?php while (have_posts()) : the_post(); ?>
        <li>
   <a href=”<?php the_permalink() ?>” title=”<?php the_title(); ?>”>
          <?php the_title(); ?></a>
   <?php the_time(‘m-d’); ?>
 </li>
      <?php endwhile; ?>
    </ul>
  </div>

</div>
<?php } ?><!-- end .post -->
		<?php endwhile; ?>

	    <?php else : ?>
	    	<div class="post not-found">
				<div class="title">
					<h2><?php _e("Not Found", "ultimo"); ?></h2>
				</div>
				<div class="clear"></div>
				
				<div class="entry no-result">
					<p class="no_result"><?php _e("Apologies, but no results were found for the requested archive. Perhaps searching will help find a related post.", "ultimo"); ?></p>
				</div>
			</div><!-- end .post -->
		<?php endif; ?>
		
		<?php if(function_exists('wp_pagenavi')) : ?>
			<div class="pagenavi">
				<?php wp_pagenavi(); ?>
			</div>
		<?php else : ?>
			<div class="pagination" style="display: none;">
				<span class="left"><?php next_posts_link(__("« Prev Page", "ultimo")); //next_posts_link points to older posts ?></span>
				<span class="right"><?php previous_posts_link(__("Next Page »", "ultimo"));//previous_posts_link points to newer posts ?></span>
				<div class="clear"></div>
			</div><!-- end .pagination -->
    	<?php endif; ?>
	
	</div><!-- end #main -->
<?php get_sidebar(); ?>
<div class="clear"></div>
</div><!-- end #container -->
<div class="clear"></div><!--ie6-->
<?php get_footer(); ?>

追问：哪个部分放到循环外？有没有办法让他 循环读取完所有分类之后 再结束
