Semalt explique comment extraire des données à partir de pages HTML dans un fichier PDF

Dans cet article, nous allons vous présenter le processus de extraire des données de vos pages HTML et enseigner comment utiliser les informations pour créer un fichier PDF. La première étape consiste à déterminer les outils de programmation et le langage que vous allez utiliser pour la tâche. Dans ce cas, vous feriez mieux d'utiliser le framework Mojolicious de Perl.

Ce framework ressemble à Ruby on Rails même s'il possède des fonctionnalités supplémentaires qui pourraient dépasser vos attentes. Nous n'utiliserons pas ce cadre pour créer un nouveau site Web mais pour extraire des informations d'une page déjà existante. Mojolicious a d'excellentes fonctionnalités pour récupérer et traiter les pages HTML. Cela vous prendra près de 30 secondes pour installer cette application sur votre machine.

Méthodologie

Première étape: Il est important de comprendre la méthodologie que vous devez utiliser pour rédiger des demandes. Dans la première étape, vous devez écrire un petit script ad-hoc après avoir eu une idée générale de ce que vous voulez faire et avoir une compréhension claire de votre objectif final. Notez que ce code linéaire doit être simple sans aucune procédure ou sous-routine.

Deuxième étape: Vous comprenez maintenant clairement la direction que vous devez prendre et les bibliothèques à utiliser. C'est le moment de "diviser pour régner"! Si vous avez accumulé des codes qui font logiquement les mêmes choses, subdivisez-les en sous-programmes. L'avantage du codage de sous-programme est que vous pouvez effectuer plusieurs changements sans impact sur les autres codes. Cela fournira également une meilleure lisibilité.

Troisième étape: Cette étape vous permet de classer vos codes. Vous pouvez manipuler des pièces de code avec facilité après avoir acquis l'expérience pertinente. Maintenant, vous pouvez passer du codage procédural à l'objet, surtout si vous utilisez un langage orienté objet. Toute personne qui utilise un type de langage fonctionnel peut séparer les applications des paquets ou / et des 'interfaces'. Pourquoi devez-vous utiliser cette approche lors de la programmation? C'est parce que vous avez besoin d'un "espace de respiration" surtout si vous écrivez une application sophistiquée.

L'algorithme

Après la théorie, il est temps de passer au programme en cours. Voici les étapes à suivre lors de l'implémentation de l'épurateur Web:

  • Créez une liste d'URL des articles que vous souhaitez collecter;
  • Bouclez votre liste et récupérez ces URL les unes après les autres;
  • Extraire le contenu de l'élément HTML;
  • Sauvegardez vos résultats dans le fichier HTML;
  • Compilez un fichier pdf de vos fichiers une fois que vous les avez tous prêts.

Tout est aussi facile que ABC! Il suffit de télécharger le programme d'épurateur Web, et vous serez prêt pour la tâche.
