What is Rawling?

Rawling, often referred to as web crawling or web scraping, is the process of systematically browsing the internet to extract data from websites. This technique involves using automated scripts or programs, commonly known as crawlers or spiders, to gather information from various online sources.

Data Types in Rawling

The types of data that can be collected through rawling include:

• Textual information
• Images and multimedia
• Meta tags and HTML structure
• Links and relationships between pages

The Mechanism of Rawling

At its core, rawling involves sending requests to web servers, retrieving the HTML content, and then parsing that content to extract the desired information. This process can be broken down into several key steps:

• Sending HTTP requests to target URLs
• Receiving and processing the HTML response
• Extracting specific data points using parsers
• Storing the extracted data in a structured format
