There are two different steps involved in Web Scraping:-

1. Crawling web pages
2. Extracting data from these web pages

Typically, there is a starting URL from where other links are discovered. You can filter these links to restrict the pages that are crawled. XPath is a wise choice for this filtering.

Once you have the HTML content of a page, you can extract any piece of information from it. Once again, XPath comes to the rescue for extracting the data.

Pay attention to the terms of use of the website you are trying to crawl. Don’t extract data from websites that forbid it.

On a side note, you can test out our Web Scraper to see how it is done.
