3. How to Use

Not sure how to handle the Page object returned by get_page? -> Playwright Method Reference

1. async with PlaywrightScraper() as scraper
   Create an instance of the scraper.
2. async with scraper.get_page("http://www.example.com/") as page:
   Get a page context using the get_page method.
3. Now you can directly use all the Playwright features on page.

🖥️ Code Example

import asyncio
from pw_simple_scraper import PlaywrightScraper

async def main():
    # Create scraper instance
    async with PlaywrightScraper() as scraper:
        # Get page context
        async with scraper.get_page("http://www.example.com/") as page:
            # >>>> Use `page` in this block! <<<<

Not sure how to handle the Page object returned by get_page? -> Playwright Method Reference

4-1. Extract title / text / attributes

🖥️ Code Example

import asyncio
from pw_simple_scraper import PlaywrightScraper

async def main():
    async with PlaywrightScraper() as scraper:
        async with scraper.get_page("https://quotes.toscrape.com/") as page:
            title = await page.title()
            first_quote = await page.locator("span.text").first.text_content()
            quotes = await page.locator("span.text").all_text_contents()
            first_author_link = await page.locator(".quote a").first.get_attribute("href")

            print("Page Title:", title)
            print("First Quote:", first_quote)
            print("Quote List (first 3):", quotes[:3])
            print("First Author Link:", first_author_link)

if __name__ == "__main__":
    asyncio.run(main())

⬇️ Example Output

First Author Link: /author/Albert-Einstein

4-2. Images & links — collect absolute paths

🖥️ Code Example

import asyncio
from urllib.parse import urljoin
from pw_simple_scraper import PlaywrightScraper

async def main():
    async with PlaywrightScraper() as scraper:
        async with scraper.get_page("https://books.toscrape.com/") as page:
            img_urls = await page.locator("article.product_pod img").evaluate_all(
                "els => els.map(el => el.getAttribute('src'))"
            )
            abs_imgs = [urljoin(page.url, u) for u in img_urls if u]

            book_urls = await page.locator("article.product_pod h3 a").evaluate_all(
                "els => els.map(el => el.getAttribute('href'))"
            )
            abs_books = [urljoin(page.url, u) for u in book_urls if u]

            print("Image URLs (5):", abs_imgs[:5])
            print("Book Links (5):", abs_books[:5])

if __name__ == "__main__":
    asyncio.run(main())

  • JS Property: input.value → changes to "user input" when typed

Category	Method	Description	Notes / Comparison

	text_content()	Returns visible text of the first element	Similar to innerText (not textContent)
	inner_text()	Same as text_content()	Actual visible text
	all_inner_texts()	List of visible text from all elements	Similar to all_text_contents()
Attribute	get_attribute('attr')	Returns HTML attribute (href, src, class)	Static, as written in HTML
Property	get_property('prop')	Returns live DOM property (value, checked)	Useful for dynamic state
HTML / Value	inner_html()	Returns inner HTML of element	Only inside structure
	outer_html()	Returns element’s full HTML	Includes element itself
	input_value()	Returns current value of form elements	More accurate than get_attribute('value')
	select_option()	Returns <option> info from <select>	Shows selected state
State (Boolean)	is_visible()	Is element visible	True/False
	is_hidden()	Is element hidden	True/False

	is_disabled()	Is element disabled	True/False
	is_editable()	Is element editable	True/False
	is_checked()	Is checkbox/radio checked	True/False
Advanced	evaluate("JS func", arg)	Runs JS on first element	Flexible extraction
	evaluate_all("JS func", arg)	Runs JS on all elements, returns list	Useful for batch data

6. FAQ
