Purifier

A simple scraping library.

It allows you to easily create simple and concise scrapers, even when the input is quite messy.

Example usage

Extract titles and URLs of articles from Hacker News:

from purifier import request, html, xpath, maps, fields, one

scraper = (
    request()
    | html()
    | xpath('//a[@class="titlelink"]')
    | maps(
        fields(
            title=xpath("text()") | one(),
            url=xpath("@href") | one(),
        )
    )
)

result = scraper.scrape("https://news.ycombinator.com")

result == [
     {
         "title": "Why Is the Web So Monotonous? Google",
         "url": "https://reasonablypolymorphic.com/blog/monotonous-web/index.html",
     },
     {
         "title": "Old jokes",
         "url": "https://dynomight.net/old-jokes/",
     },
     ...
]
