Pendant un certain temps, Magento 2 avait un moyen de valider (et de compléter automatiquement) n'importe quel xml en utilisant un fichier XSD.
Par exemple, cela module.xmlressemblait à ceci:

<?xml version="1.0">
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/Module/etc/module.xsd">
    ....
</config>

mais module.xmlressemble maintenant à ceci:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    ....
</config>

donc l' xsi:noNamespaceSchemaLocationattribut contient urn:magento:framework:.

Je sais que cela n'a rien à voir avec la validation côté serveur des xml. Celui-ci fonctionne toujours.
Mais que puis-je faire pour récupérer ma validation dans mon IDE (PHPStorm dans mon cas, mais ce n'est pas important, ça peut être autre chose) afin de reconnaître le chemin vers le xsd?
Dois-je toujours utiliser l'ancien chemin relatif lors de la construction de mes modules? Ou existe-t-il une meilleure façon de procéder?

Vérifiez les mises à jour du GitHub aujourd'hui, Magento 2 a introduit une nouvelle commande pour générer automatiquement toutes les résolutions URN pour PhpStorm.

Pour l'utiliser:

• avoir Magento installé sur la même machine que PhpStorm
• allez dans le répertoire racine
• exécuter la commande bin/magento dev:urn-catalog:generate .idea/misc.xmloù .idea/misc.xmlest le chemin vers votre fichier misc.xml PhpStorm

Tous les URN devraient être résolus comme par magie maintenant!

Vérifiez-les sous PhpStorm->Preferences -> Languages&Frameworks -> Schemas and DTDs

PhpStorm 9.0 (Windows): File -> Settings -> Languages&Frameworks -> Schemas and DTDs

Magento a donc changé l'URI XSD pour utiliser les urnes - celles-ci doivent être configurées dans PHP Storm pour que la validation du schéma fonctionne à nouveau.

Le code de résolution URN est directement intégré à Magento. Heureusement, il est assez facile d'associer des URN à de vrais fichiers dans votre site local en PHP Strom.

C'est ce que vous verrez après avoir chargé une nouvelle version de magento2 avec des urnes. Notez que l'URN est en rouge car PHP Storm ne sait pas comment le résoudre.

Placez le curseur dans l'URN puis cliquez sur l'ampoule rouge à gauche qui apparaîtra et sélectionnez «Configuration manuelle des ressources externes» dans la liste.

Faites défiler la liste des fichiers XSD que PHP Storm a automatiquement localisés et sélectionnez le fichier approprié. L'URN rouge sera maintenant affiché en vert et la validation XML est de retour.

La génération URN est prise en charge par le plugin Magento 2 pour PHP Storm, et n'est qu'une des nombreuses fonctionnalités utiles qu'elle fournit aux développeurs de Magento 2.

Lorsque le plugin est installé dans PHP Storm, accédez à Preferences / Other Settings / Magento2 plugin et cliquez sur Regenerate URN map.

Utilisateurs Eclipse IDE:

(Mis à jour le 11 juillet 2019 pour Magento 2.3.1)

Avantages:

• Eclipse reconnaîtra le chemin vers les XSD et tous les avantages que cela apporte.

Les inconvénients:

• La configuration est à la portée de l'espace de travail, pas à la portée du projet.
• Vous devez le configurer manuellement.
• Si Magento ajoute de nouveaux XSD dans les futures versions ou modifie le chemin d'accès, vous devrez gérer manuellement ces modifications.

Instructions:

• À l'aide de votre gestionnaire de fichiers préféré, accédez à la racine du répertoire de l'espace de travail de votre Eclipse. Si sous Linux, et que vous utilisez simplement l'emplacement par défaut de l'espace de travail, il est très probable ~/workspace.
• Dans votre répertoire d'espace de travail eclipse, recherchez .metadata/.plugins/org.eclipse.wst.xml.core/user_catalog.xml(s'il n'existe pas, créez-le)
• Collez le contenu ci-dessous et remplacez "ROOT" par votre chemin réel:
