Générer un XML d’exemple à partir du XSD

Magento 2 possède des XSD qui permettent de définir les structures que devront respecter vos fichiers XML.
Il existe un outil simple mais efficace qui, en fournissant le XSD, vous donnera un XML d’exemple.
Pratique pour avoir la visualisation d’un fichier de config par exemple.

Rendez-vous sur : http://xsd2xml.com/

Prenons pas exemple le XSD suivant :
/lib/internal/Magento/Framework/App/etc/routes.xsd

Voici son contenu :

<?xml version="1.0" encoding="UTF-8"?>

Et après l’avoir inséré dans l’outil de conversion, voici le XML généré :

<?xml version="1.0" encoding="utf-8"?>
<config>
  <router id="str1234">
    <route id="str1234" frontName="str1234">
      <module name="str1234" before="str1234" after="str1234" />
    </route>
  </router>
</config>
