Python web-scraping library that wraps urllib2 and BeautifulSoup

BeautifulScraper

Simple wraper around BeautifulSoup for HTML parsing and urllib2 for HTTP(S) request/response handling. BeautifulScraper also overrides some of the default handlers in urllib2 in order to:

• Handle cookies properly
• Offer full control of included cookies
• Return the actual response from the server, un-mangled and not reprocessed

Installation

# pip install beautifulscraper

or

# git clone git://github.com/adregner/beautifulscraper.git
# cd beautifulscraper/
# python setup.py install

Examples

Getting started is brain-dead simple.

>>> from beautifulscraper import BeautifulScraper
>>> scraper = BeautifulScraper()

Start by requesting something.

>>> body = scraper.go("https://github.com/adregner/beautifulscraper")

The response will be a plain BeautifulSoup object. See their documentation for how to use it.

>>> body.select(".repository-description")[0].text
u'\nPython web-scraping library that wraps urllib2 and BeautifulSoup\n'

The headers from the server's response are accessiable.

>>> for header, value in scraper.response_headers.items():
...     print "%s: %s" % (header, value)
... 
status: 200 OK
content-length: 36179

So is the response code as an integer.

>>> type(scraper.response_code), scraper.response_code
(<type 'int'>, 200)

The scraper will keep track of all cookies it sees via the cookielib.CookieJar class. You can read the cookies if you'd like. The Cookie object's are just a collection of properties.

>>> scraper.cookies[0].name
'_gh_sess'
