   Hi, I am trying without success to list in a page the children titles and their children.
   Something like:
   Programs:
   program 1
   Sub program1 1

   program 2
   Sub program2 1
   Sub program2 2
   Sub program2 3

   program 3
   Sub program3 1

   but instead I am getting:

   Programs:
   program 1
   Sub program1 1

   program 2
   Sub program2 1
   Sub program2 2
   Sub program2 3

   program 3
   Sub program3 1

   Sub program1 1
   Sub program2 1
   Sub program2 2
   Sub program2 3
   Sub program3 1

   meaning that i get the corretly listing at first but then i get the childs all totheger

   this my code:

   `<?php
   // Set up the objects needed
   $my_wp_query = new WP_Query();
   $all_wp_pages = $my_wp_query->query(array('post_type' => 'page'));

   // Get the page as an Object
   $programs = get_page_by_title('programs');

   $program_children = get_page_children($programs->ID, $all_wp_pages);

   foreach($program_children as $post) :
   echo '<h2 class="title">'.get_the_title().'</h2>';
   $program_childrenL2 = get_page_children(get_the_ID(), $all_wp_pages);
   foreach($program_childrenL2 as $postL2) :
   setup_postdata($postL2);
   echo '<h3 class="title">'.$postL2->ID.'</h3>';
   endforeach;
   endforeach;

   ?>`

   Is there a reason you aren't using the wp_list_pages function? http://codex.wordpress.org/Function_Reference/wp_list_pages
   Perhaps I'm not understanding exactly what you're using this code for.

   Ya wp_list_pages is ok, and do a very close job to what i need but i want to have the content or excerpt as well, not just the titles of the pages.

   I believe get_page_children will get all children, which includes grandchildren, and so they show again at the bottom because they are a part of your $program_children array.

   Seems to me that you should be able to use get_pages for $all_wp_pages (though then should rename your variable) so you're not retrieving all the pages with your query, as it's unnecessarily expensive. I could be wrong about the type it returns vs. the type get_page_children expects, though. I actually strongly suspect that there might be a better way entirely to do this, and may think on it some more.
