Creating wordpress dump(.wxr) using unix and mysql
As blogged here, all you need is the export_wp function, so run something along the lines of.
include 'wp-config.php';include 'wp-admin/includes/export.php';ob_start();export_wp();$file = ob_get_contents();ob_end_clean();$fh = fopen("wordpress-" . date('Y-m-d') . ".xml", 'w');fwrite($fh, $file);fclose($fh);Then just grab the .xml file generated!
