As you can see from the image, we have a left bar that contains links for the site's product categories. Our first step is to investigate the site's HTML and plan how we wish to scrape it.

The fashion site categories have subcategories (Men, Women, Kids).

Let's set up a project.

  1. Create a new Console App or add a new folder for our new sample with the name “ShoppingSiteSample”.
  2. Add a new class with the name “ShoppingScraper”.
  3. The first step will be to scrape the site categories and their subcategories.

Let’s create a Categories Model:

public class Category
{
    /// <summary>
    /// Gets or sets the name.
    /// </summary>
    /// <value>
    /// The name.
    /// </value>
    public string Name { get; set; }

    /// <summary>
    /// Gets or sets the URL.
    /// </summary>
    /// <value>
    /// The URL.
    /// </value>
    public string URL { get; set; }

    /// <summary>
    /// Gets or sets the subcategories.
    /// </summary>
    /// <value>
    /// The subcategories.
    /// </value>
    public List<Category> SubCategories { get; set; }
}
public class Category
{
    /// <summary>
    /// Gets or sets the name.
    /// </summary>
    /// <value>
    /// The name.
    /// </value>
    public string Name { get; set; }

    /// <summary>
    /// Gets or sets the URL.
    /// </summary>
    /// <value>
    /// The URL.
    /// </value>
    public string URL { get; set; }

    /// <summary>
    /// Gets or sets the subcategories.
    /// </summary>
    /// <value>
    /// The subcategories.
    /// </value>
    public List<Category> SubCategories { get; set; }
}
Public Class Category
	''' <summary>
	''' Gets or sets the name.
	''' </summary>
	''' <value>
	''' The name.
	''' </value>
	Public Property Name() As String

	''' <summary>

	Public Property URL() As String

	''' <summary>
	''' Gets or sets the subcategories.
	''' </summary>
	''' <value>
	''' The subcategories.
	''' </value>
	Public Property SubCategories() As List(Of Category)

Scraping links from the menu:

Let’s update our code to scrape the Main Categories and all its sub-links:

public override void Parse(Response response)

To scrape category pages, we add a new scrape method:

public void ParseCategory(Response response)
{
    // List of Products
    var productList = new List<Product>();

    // Iterate through product links in the product section
    foreach (var Links in response.Css("section.products > div > a"))
    {
        var product = new Product
        {
            Name = Links.Css("h2.title > span.name").First().InnerText,
            Price = Links.Css("div.price-container > span.price-box > span.price > span[data-price]").First().InnerText,
            Image = Links.Css("div.image-wrapper.default-state > img").First().Attributes["src"]
        };

        productList.Add(product);
    }

    // Save the scraped product data into a JSONL file.
    Scrape(productList, "Products.jsonl");
}
public void ParseCategory(Response response)

Vous pouvez utiliser IronWebScraper pour extraire des catégories de produits en examinant la structure HTML du site, en particulier dans la barre latérale listant les catégories. Initialisez l'extracteur, définissez un modèle 'Category' avec des propriétés comme le nom et l'URL, et utilisez l'extracteur pour extraire ces données.

Quelles étapes sont impliquées pour configurer un extracteur Web pour un site de shopping ?

Commencez par créer une nouvelle application console C# et une classe, telle que 'ShoppingScraper'. Utilisez IronWebScraper pour initialiser l'extracteur, définir les URL cibles, et définir la logique d'extraction pour extraire les catégories et les détails des produits.

Comment puis-je extraire et sauvegarder les détails des produits à l'aide d'un extracteur web ?

Avec IronWebScraper, vous pouvez extraire les détails du produit comme les noms, les prix et les images en définissant un modèle 'Product'. Utilisez l'extracteur pour analyser les pages de catégories et enregistrez les données extraites dans des fichiers JSONL en utilisant la méthode Scrape.

Quel est le rôle du modèle 'Category' dans l'extraction web ?

Le modèle 'Category' sert de structure de données pour stocker des informations sur chaque catégorie de produit, y compris son nom, son URL et ses sous-catégories, facilitant une extraction de données organisée avec IronWebScraper.

Comment IronWebScraper gère-t-il l'extraction des sous-catégories ?

IronWebScraper gère les sous-catégories en itérant à travers les liens de sous-catégories au sein de chaque catégorie principale, les ajoutant à la liste 'SubCategories' du modèle 'Category' respectif pour une extraction complète.

Quels sont les défis courants lors de l'extraction de données sur les sites de shopping ?

Les défis courants incluent la gestion du contenu dynamique JavaScript, la gestion de la pagination, l'adaptation aux changements de structure du site et le respect des contraintes légales et techniques comme robots.txt.

IronWebScraper peut-il extraire les tailles des produits d'un site de shopping ?

Oui, IronWebScraper peut capturer les tailles de produits en identifiant les informations de taille dans les détails du produit et en les stockant dans les données produit extraites.

Comment vérifiez-vous l'exactitude des données extraites par le web ?

Assurez-vous de l'exactitude en inspectant le HTML du site, en utilisant des sélecteurs CSS précis, et en testant l'extracteur sur diverses pages pour confirmer une extraction de données cohérente et correcte.

Comment puis-je améliorer un extracteur pour récupérer tous les sous-liens d'une page ?

Améliorez votre extracteur en affinant la logique d'extraction pour suivre et extraire des données de tous les sous-liens d'une page, en assurant une collecte de données complète en utilisant les capacités d'IronWebScraper.
