Automated Web Scraping and AI Analysis with Selenium
detail.loadingPreview
This n8n workflow automates advanced web scraping using Selenium, extracts specific data, cleans browser traces, and leverages OpenAI for intelligent analysis. It's designed for efficient and sophisticated data acquisition from websites.
About This Workflow
The Selenium Ultimate Scraper Workflow is a powerful n8n solution for extracting precise information from websites. It begins by initiating a Selenium session to navigate and interact with web pages. The workflow then intelligently extracts specific data points, such as URLs, based on defined CSS selectors. To ensure stealthy operations, it meticulously cleans browser traces, making scraped data harder to detect. Following data extraction, an OpenAI Chat Model (GPT-4o) is utilized for advanced analysis or transformation of the scraped content. The workflow also includes robust session management, ensuring that Selenium sessions are properly created and terminated, even in the event of errors, preventing resource leaks and maintaining workflow stability. This comprehensive approach makes it ideal for complex web scraping tasks requiring both precision and intelligent processing.
Key Features
- Advanced Web Scraping: Utilizes Selenium for dynamic website interaction.
- Intelligent Data Extraction: Pinpoints and extracts specific HTML content and attributes using CSS selectors.
- Stealthy Scraping: Employs a script to remove Selenium's detection markers from the browser environment.
- AI-Powered Analysis: Integrates OpenAI's GPT-4o for sophisticated content analysis and processing.
- Robust Session Management: Ensures clean creation and deletion of Selenium sessions to prevent errors and resource waste.
How To Use
- Set up Selenium Grid: Ensure your Selenium Grid (e.g.,
selenium_chrome) is accessible athttp://selenium_chrome:4444/wd/hub. - Configure Website Domain: In the 'Extract First Url Match' node, update the
Website Domaineparameter to target the specific domain you wish to scrape. - Set up OpenAI Credentials: Connect your OpenAI account via the 'OpenAI Chat Model' node using your API key.
- Define Extraction Logic: Adjust the
cssSelectorin the 'Extract First Url Match' node to precisely target the URLs or elements you need to extract. - Customize AI Prompt: Within the 'OpenAI Chat Model' node, configure the prompt to guide GPT-4o's analysis based on the extracted data.
- Review Session Management: The workflow includes nodes for creating and deleting Selenium sessions. Ensure these are correctly linked and configured, especially the
sessionIdpassed between nodes. - Error Handling: The 'Delete Session4' node is configured with
onError: continueRegularOutputto gracefully handle session deletion failures. Review and adjust error handling as needed for your specific use case.
