As its name suggests, Web Scraping is a tool that pulls data from websites. It is an automated procedure in which a program parses the HTML of a web page in order to extract data for further processing, for instance. It translates a web page to a different format and stores it in a local database or spreadsheet for subsequent retrieval and study.
There has been a 33.33% rise in the number of job positions for this post in 2022. Thus, learning web scraping with Selenium is a very good career choice for the future.
Selenium is well-known for its usage in automated testing. However, Selenium has further applications. Web scraping is a vital use of Selenium. This post will examine whether you should use Selenium or other technologies, such as Beautiful Soup, for web scraping.
What exactly is Web scraping?
Web Scraping, often known as "Crawling" or "Spidering," is the process of autonomously gathering data from an online source, typically a webpage. While Web Scraping is a simple approach to obtaining a large amount of data quickly.
This is also one of the primary reasons why many websites prohibit scraping entirely.
The usefulness of Selenium for Web Scraping
Since WebDriver utilizes a real web browser to view the page, it is identical to human or robot online browsing. When you visit a website using Webdriver, the browser loads all of the website's resources (JavaScript files, pictures, CSS files, etc.) and executes all of the JavaScript on the page. Additionally, it keeps all cookies generated by your websites.
makes it extremely difficult to tell whether the website was viewed by a human or a machine. This is doable in a few easy steps using Webdriver, but it is quite difficult to duplicate all these operations with software that sends hand-crafted HTTP requests to the server.
To extract data from these browsers, Selenium offers the WebDriver module, which is helpful for a variety of activities like automated testing, cookie retrieval, snapshot retrieval, and more. Form submission, auto-login, data insertion and deletion, and alert management are frequent Selenium use cases for web scraping.
