How to add ids to page list items

Hi there,

I need to modify the result of wp_list_pages() function so I can have ids inside the returned

• .

I know I can go to the file classes.php and add the id manually inside the function start_el() but this is not a good technique because I have to modify the core code.

I’m using gengo plugin and here is my code:
PHP

<ul id="menu-pages">
    <?php wp_list_pages('sort_column=menu_order&title_li=' ); ?>
  </ul>

HTML

<ul id="menu-pages" class="ui-sortable" style="position: relative;">
  <li class="page_item page-item-4 current_page_item"><a title="Home" href="https://.../home/en/">Home</a></li>
...
</ul>

And this is what I need:
HTML

<ul id="menu-pages" class="ui-sortable" style="position: relative;">
  <li id="page-home" class="page_item page-item-4 current_page_item"><a title="Home" href="https://.../home/en/">Home</a></li>
...
</ul>
