Le script d’Xpath Trainer se contentant de récupérer le contenu du fichier sélectionné pour l’afficher dans une iframe d’une part et d’autre part le fournir à [xpath](https://www.npmjs.com/package/xpath) pour y tester les chemins saisis par l’utilisateur.

La simplicité du script fait qu’il n’y a pas de tests unitaires.
La simplicité du script fait qu’il n’y a pas de tests unitaires.
## Limites
L'affichage de manière lisible d'un fichier XML sans feuille de style dans l'iframe ne fonctionne que dans Firefox.
La gestion des attributs et des espaces de nom reste à améliorer.
