Introduction to Crawling
Crawling is designed as a specialized tool focused on web scraping, particularly adept at handling dynamic web elements using Python 3.9 and Selenium 4. This tool is crafted to assist in navigating through websites that dynamically generate content, often changing in response to user actions or live data updates. By leveraging the capabilities of Selenium 4, Crawling can interact with web elements that would be inaccessible to basic HTTP request-based scraping tools, simulate user actions such as clicks and keystrokes, and manage complex scenarios like infinite scrolling or AJAX-based pagination. An example scenario illustrating its use is extracting real-time stock market data from a financial website where stock prices are frequently updated. Crawling would be able to programmatically navigate the site, interact with date range filters, and scrape the updated data without manual intervention. Powered by ChatGPT-4o。
