How can I modify the AI Scraper Selenium App to handle dynamic content loading on websites?
To handle dynamic content loading, you can add a wait function in the SeleniumUtility
class. Here's an example of how to implement this:
```python from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.support import expected_conditions as EC from selenium.webdriver.common.by import By
class SeleniumUtility: # ... existing code ...
def wait_for_element(self, by, value, timeout=10):
return WebDriverWait(self.driver, timeout).until(
EC.presence_of_element_located((by, value))
)
def get_page_text(self, url: str):
try:
self.open_url(url)
# Wait for the body to load
body = self.wait_for_element(By.TAG_NAME, "body")
return body.text
except Exception as e:
logger.error(f"Failed to retrieve page text for {url}: {e}")
finally:
self.close()
```
This modification allows the AI Scraper Selenium App to wait for specific elements to load before extracting the page content.
Can the AI Scraper Selenium App handle websites with CAPTCHAs, and if so, how?
Yes, the AI Scraper Selenium App has a basic mechanism to handle CAPTCHAs. In the process_page_info
function, there's a retry loop that checks for the presence of a CAPTCHA:
python
retries = 0
while "Captcha" in page_text and retries < 5:
page_text = selenium_util.get_page_text(url)
retries += 1
This code attempts to reload the page up to 5 times if a CAPTCHA is detected. However, for more sophisticated CAPTCHA handling, you might need to integrate a CAPTCHA-solving service or implement image recognition techniques. It's important to note that bypassing CAPTCHAs may violate some websites' terms of service, so always ensure you have permission to scrape the target website.

Here's a step-by-step guide on how to use the AI Scraper Selenium App template:
Introduction
The AI Scraper Selenium App is a powerful tool that allows you to scrape web pages and extract information using Selenium and AI. This template provides a foundation for building web scraping applications with a user-friendly interface.
Getting Started
- Click "Start with this Template" to begin using the AI Scraper Selenium App template in the Lazy Builder interface.
Test the App
- Press the "Test" button to deploy the app and launch the Lazy CLI.
Using the App
-
Once the app is deployed, you'll receive a server link to access the web interface.
-
Open the provided link in your web browser to access the AI Scraper Selenium App interface.
-
You'll see a form with two input fields:
- URL: Enter the web page URL you want to scrape.
-
Question: Enter a question about the information you want to extract from the page.
-
Click the "Submit" button to process your request.
-
The app will use Selenium to scrape the specified web page and extract relevant information based on your question.
-
After processing, you'll see a table displaying the extracted information on the results page.
How It Works
- The app uses Selenium to navigate to the specified URL and extract the page content.
- It then uses an AI model (GPT-4) to analyze the page content and answer your question.
- The results are presented in a structured JSON format, which is then displayed in a table on the results page.
Customization
You can customize this template by modifying the following files:
main.py
: Adjust the FastAPI routes and logic for processing requests.selenium_utils.py
: Modify the Selenium utility class to add more scraping functionality.form.html
andpage_information.html
: Customize the HTML templates for the user interface.
Remember that all customizations should be done within the Lazy Builder interface.
By following these steps, you'll be able to use the AI Scraper Selenium App template to create powerful web scraping applications with AI-powered information extraction.
