Within the demo beneath we are going to scrape the info from Macy’s web site and export the info to a CSV file. We are going to focus on methods to get product element data from their House class.
Let’s get began!
The way it works
Step 1: You’ll must obtain the Chrome browser should you don’t have already got it together with WebScraper.io, which is a Chrome extension.

Give your sitemap a reputation together with the URL the place you need the scraper to start out.
For our Macy’s instance, we will probably be beginning on the Homepage. Additionally, be certain that to go to the web page within the browser. Since this software works within the browser, we navigate by way of the location whereas establishing our sitemap.
Step 4: After establishing the preliminary start line, you’ll be capable of add the primary selector. A selector is actually what you need the net scraper to do subsequent.

Just remember to’re inside the foundation selector and choose the add new selector button.
Step 5: This step is about establishing the House hyperlink selector. We wish the scraper to pick the House class from Macy’s Homepage so we are able to then enter the house items part of the web site. The kind of selector will probably be a hyperlink since choosing this button will hyperlink us to that part of the location. We give the selector an ID and select the kind of the Sort area.In our case, this will probably be a Hyperlink kind.

In our sitemap you’ll want to choose the earlier selector, “home_link”.
We do that as a result of it’s a hierarchical setup by which we navigate the location so this new selector will probably be a toddler of the earlier one. As soon as we’re within “home_link” we add a brand new selector. Within the browser navigate to the House class, and it’s best to see on the left facet of the web page subcategories below “House Classes”.
Fill out the ID area (I name it home_categories_links) and the Sort area as Hyperlink. Choose “A number of” beneath the Selector area after which allow key occasions within the Component preview. Then maintain S in your keyboard and begin choosing the hyperlinks below House Classes.
After you choose two of the hyperlinks, the scraper is wise sufficient to detect the sample and choose the remainder of the hyperlinks which have frequent factor data for each hyperlink. This manner when the scraper is navigating the location, it’ll understand it has to undergo all of these subcategories and get product data. Make sure that the factor’s data is within the Selector area after which save the selector.
Step 7: Choose the product hyperlinks below the subcategories. To get a product’s particulars, we want the scraper to pick the product from every subcategory.

Within the browser, choose one of many subcategories, so we’re on that web page.

Step 8: Choose the product element data you need. Ensure you’re contained in the “home_categories_links” selector and create a brand new selector. Within the browser choose one of many merchandise from the subcategory so that you simply‘re on that product’s element web page.

As soon as you choose “Begin Scraping”, a secondary browser will launch that permits you to observe the scraping in progress.
