How can I modify the Playwright Text Scraper to scrape multiple pages?

To scrape multiple pages, you can modify the main() function in the playwright_cli_demo.py file. Here's an example:

```python async def main(): async with async_playwright() as p: browser = await p.chromium.launch() page = await browser.new_page()

       urls = ["http://example.com", "http://example.org", "http://example.net"]

       for url in urls:
           await page.goto(url)
           title = await page.title()
           print(f"Title of the page {url}: {title}")

           text_elements = await page.query_selector_all("body >> visible=true")
           print(f"Content of text elements on {url}:")
           for element in text_elements:
               text_content = await element.text_content()
               if text_content:
                   print(text_content.strip())

           print("\n---\n")

       await browser.close()

```

This modification allows the Playwright Text Scraper to iterate through multiple URLs and scrape content from each.

How can I add error handling to the Playwright Text Scraper?

To add error handling, you can use try-except blocks in the main() function. Here's an example:

```python async def main(): async with async_playwright() as p: try: browser = await p.chromium.launch() page = await browser.new_page() await page.goto("http://example.com")

           title = await page.title()
           print(f"Title of the page: {title}")

           text_elements = await page.query_selector_all("body >> visible=true")
           print("Content of text elements on the page:")
           for element in text_elements:
               text_content = await element.text_content()
               if text_content:
                   print(text_content.strip())

       except Exception as e:
           print(f"An error occurred: {str(e)}")

       finally:
           if 'browser' in locals():
               await browser.close()

```

This modification adds error handling to catch and print any exceptions that occur during the scraping process, ensuring that the browser is closed properly even if an error occurs.
