yes, you can with recursive and tree output to true

and then you extract only "sub_categories"

a little example:

Code:

<?php
$objXml = new SimpleXmlElement(file_get_contents('http://demo.piwigo.com/ws.php?format=rest&method=pwg.categories.getList&recursive=true&tree_output=true'));
foreach($objXml->item as $value) { //loop the response
  if ($value->sub_categories) { //if item has subcategories
    foreach ($value->sub_categories->category as $value) { //loop the subcategories
      echo strval($value->name) . '<br>' . PHP_EOL; //show the subcategory names
    }
  }
}
?>

order by last updated

i didn't saw this first time when i read. yes you can also order by last updated but is a little more complicated.
PLG already made something similar
http://piwigo.org/forum/viewtopic.php?p … 34#p158834
as you can see he put the result in an array with also the date, then he sort the array.

@edit
you can put the date as key of the array value then you can can use ksort http://php.net/manual/ro/function.ksort.php , i find it more simple

Great, that's what I need too.
Thank you!
