All you need to know about web scraping as a method of extracting data from websites.
Web scraping is the method of extracting structured information from a web page. It means that web scraping automates manually finding and saving the information on a website you find valuable. Although web scraping can be done manually, in most cases, automatic tools are favored when scraping web data as they can be less costly and work at a faster rate.
How does Web Scraping work?
3 simple steps can represent a general web scraping case:
- Request a web page content by URL (open the web page to get the HTML content) or via the direct API call.
- Convert the mess of the HTML tags into extracted and structured data by parsing (like we do it when a copy-pasting particular text part).
- Store the extracted data into preferred storage: database, text file, CSV, Excel, etc.
