You are browsing a tutorial guide for the latest Octoparse version. If you are running an older version of Octoparse, we strongly recommend you upgrade because it is faster, easier and more robust! Download and upgrade here if you haven't already done so!

Walmart is a large retail corporation in the United States. In this tutorial, we are going to show you how to scrape product data from Walmart.com.

You can also go to "Task Templates" on the main screen of the Octoparse scraping tool, and start with the ready-to-use Walmart Template directly to save your time. With this feature, there is no need to configure scraping tasks. For further details, you may check it out here: Task Templates

If you would like to know how to build the task from scratch, you may continue reading the following tutorial.

Suppose we want to scrape some specific information about headphones, and we can start with the home page (https://www.walmart.com/) to create our crawler. We will scrape data such as product title, price, product ID, and reviews from the product details page with Octoparse.

Here are the main steps in this tutorial: [Download demo task file here]

Open the target web page
Create a Pagination - to scrape from multiple pages
Scrape data from the product list
Click into each product link to scrape data - to get data from product pages
Extract data from the detail page
Run extraction - run your task and get data

1. Open the target web page

Enter the URL on the home page and click Start

Click the search box and then click Enter text on the Tips panel

Type "Headphone" and confirm

Click on Enter Text and set as to hit the Enter/Return key, then click "Apply" to confirm

2. Create a Pagination - to scrape from multiple pages

Click on , select Loop click single element, and set up the AJAX timeout as 10s

The auto-generated XPath for Pagination does not always work in this case, so we need to modify the XPath to make it scrape all the pages.

Click on Pagination
Input the XPath //a[@aria-label="Next Page"] in the Matching XPath box
Click Apply to confirm

3. Scrape data from the product list

Select the first product (note to include the whole product section)
Choose Select all sub-elements

Choose Select all

Choose Extract Data

Now, a Loop Item with Extract Data will be created in the workflow

Double click the field name to rename it or click ... to delete unwanted fields

If all the data you want can be scraped from the listing page, you can jump to step 6. Run extraction - run your task and get data

4. Click into each product link to scrape data - to get data from product pages

Some information like product description can only be grabbed from the product detail page. We need to click on each product link to get the data.

Click on the first product link
Choose Click URL

A click item will be created in the workflow:

5. Extract data from the detail page

Select the data you want
Click Extract the text of the element or Extract the URL of the select image

Double click the field name to rename it or click ... to delete fields

Set up wait time for Extract Data action

The auto-generated XPath of the data fields may fail to work after the web page updates. We will need to modify the XPath of the fields. Don' worry, we have prepared some useful XPath for this website.
