Site Scraping Framework

Grab is a python site scraping framework. Grab provides powerful interface to two libraries: lxml and pycurl. There are two ways how to use Grab: 1) Use Grab to configure network requests and to process fetched documents. In this way you should manually control flow of you program. 2) Use Grab::Spider to buld asynchronous site scrapers. This is how scrapy works.

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()
