Displaying wordpress top level pages may be useful for displaying sitemap or browse interface on a wordpress site. Here is the code you can use for this:
// List of pages you want to exclude.
// Put null if nothing needs to be excluded.
$exclude = "1000,1001";
$args = array(
'depth' => 1,
'show_date' => '',
'date_format' => get_option('date_format'),
'child_of' => 0,
'exclude' => $exclude,
'include' => '',
'title_li' => __(''),
'echo' => 1,
'authors' => '',
'sort_column' => 'menu_order, post_title',
'link_before' => '',
'link_after' => '',
'walker' => '',
'post_type' => 'page',
'post_status' => 'publish'
);
wp_list_pages($args);
Note that we are using depth=1 and child_of value 0 to find top level pages.
