how to call a remote wordpress to use his content in a loop

Hi
I know that to call the content of a wordpress site (locally) I need to put the following code in the first line of my php page

<?php 
define(‘WP_USE_THEMES’, false);
require('/blog/wp-blog-header.php');
?>

Select allOpen in new window

But i would like to know if its possible to call the content from a remote wordpress site, for example something like:

<?php 
define(‘WP_USE_THEMES’, false);
require('http://www.grupossc.com/blog/wp-blog-header.php');
?>

Select allOpen in new window
