C'est gros c'est pas beau. Bon pour le $vars['convertguid']->info sa contient par exemple le input/text d'information complémentaire

en fait les $vars['converguid']-> contient la valeur que je lui ai associé avec le nom situé après le ->.

Donc voilà il s'agit du fichier xml de CVEuropass si quelqu'un pourrais maider à comprendre un peu vu que c'est la première fois que j'en fait un.

Merci
