Invoices showing up in Sitemap

Hello guys,

I have a bigger problem with the invoices links. They show up in my sitemap, where I use the following code to show the content in 3 rows, the Invoices show up in the first row with the directory entries in first place. The row starts with: <div class=”sitemap-spalte1″>

<div class="sitemap">   
    <a name="sitemap-spalte1"></a>
    <div class="sitemap-spalte1"> 
        <h2 id="custom_posts" class="hop-schrift">Dienstleister / Events / Trauorte</h2> 
        <?php 
            foreach( 
                get_post_types( array('public' => true) ) as $post_type ) { 
                    if ( in_array( $post_type, array('post','page','attachment') ) ) continue; 
                    $pt = get_post_type_object( $post_type ); 
                    echo '<h2>'.$pt->labels->name.'</h2>'; 
                    echo '<ul>'; 
                        query_posts('post_type='.$post_type.'&posts_per_page=-1'); 
                        while( have_posts() ) { 
                            the_post(); 
                            echo '<li><a href="'.get_permalink().'">'.get_the_title().'</a></li>';
                            } 
                    echo '</ul>'; }

        ?>
    </div>
    <a name="sitemap-spalte2"></a>
    <div class="sitemap-spalte2"> 
        <h2 id="posts" class="hop-schrift">Beiträge</h2> 
            <?php   
                    $cats = get_categories('exclude='); 
                     foreach ($cats as $cat) { echo "<h3>".$cat->cat_name."</h3>"; 
                     echo "<ul>"; 
                     query_posts('posts_per_page=-1&cat='.$cat->cat_ID);
                     while(have_posts()) { the_post();
                     $category = get_the_category(); 
                     if ($category[0]->cat_ID == $cat->cat_ID) { echo '<li><a href="'.get_permalink().'">'.get_the_title().'</a></li>'; } } echo "</ul>";} 
            ?> 
    </div>
    <a name="sitemap-spalte3"></a>
    <div class="sitemap-spalte3"> 
        <h2 id="pages" class="hop-schrift">Seiten</h2> 
            <?php // Add pages you'd like to exclude in the exclude here wp_list_pages( array( 'exclude' => '', 'title_li' => '', ) ); 
                  wp_list_pages( array( 'exclude' => false, ) );
            ?> 
    </div>
</div>

You have any idea how I should change my script, so the invoices don`t show up in the sitemap.

Thank you very much,
Atilla
