Grab is a python site scraping framework. Grab provides tons of helpful methods to scrape web sites and to work with scraped content:

  • Automatic cookies (session) support
  • HTTP and SOCKS proxy with and without authorization
  • Keep-Alive support
  • IDN support
  • Tools to work with web forms
  • Easy multipart file uploading
  • Flexible customization of HTTP requests
  • Automatic charset detection
  • Powerful API of extracting info from HTML documents with XPATH queries
  • Asynchronous API to make thousands of simultaneous queries. This part of library called Spider and it is too big to even list its features in this README.
  • Python 3 ready
  • And much, much more
  • Grab has written by the guy who is doing site scraping since 2005

Check out docs: https://github.com/lorien/grab/tree/master/docs2/source

I am working hard now (Sep 2013) to complete the documentation in English.

Example of Grab usage:

from grab import Grab

g = Grab()
g.go('https://github.com/login')
g.set_input('login', 'lorien')
g.set_input('password', '***')
g.submit()
for elem in g.doc.select('//ul[@id="repo_listing"]/li/a'):
    print '%s: %s' % (elem.text(), elem.attr('href'))

Example of Grab::Spider usage:

from grab.spider import Spider, Task
import logging

class ExampleSpider(Spider):
    def task_generator(self):
        for lang in ('python', 'ruby', 'perl'):
            url = 'https://www.google.com/search?q=%s' % lang
            yield Task('search', url=url)

    def task_search(self, grab, task):
        print grab.doc.select('//div[@class="s"]//cite').text()


logging.basicConfig(level=logging.DEBUG)
bot = ExampleSpider()
bot.run()
