Scraping is a powerful tool used to gather information to be used in directory websites. It involves the extraction of data from websites, which is then often used for information aggregation, data analysis, or to populate a database for a new website.
Scraping is typically done using automated scripts or bots. These bots visit a web page, interpret its HTML code, and extract the desired information. This information can then be saved to a local file or a database in table (spreadsheet) format.
- Step 1: The bot makes a request to the website and receives the HTML of the page in response.
- Step 2: The bot parses the HTML, identifying the parts of the page that contain the desired information.
