This is just a very basic example of web scraping on your own.
For more advanced parsing, you can improve the regular expression, or look into a module like Beautiful Soup.
I pasted the code from this specific video below, though some superior regex would be something like:
import time
import urllib2
from urllib2 import urlopen
import re
import cookielib, urllib2
from cookielib import CookieJar
import datetime
cj = CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
opener.addheaders = [('User-agent', 'Mozilla/5.0')]
def main():
try:
page = 'http://feeds.huffingtonpost.com/huffingtonpost/raw_feed'
sourceCode = opener.open(page).read()
#print sourceCode
try:
titles = re.findall(r'<title>(.*?)</title>',sourceCode)
links = re.findall(r'<link.*?href=\"(.*?)\"',sourceCode)
#for title in titles:
#print title
for link in links:
if '.rdf' in link:
pass
else:
print 'let\'s visit:', link
linkSource = opener.open(link).read()
content = re.findall(r'<p>(.*?)</p>',linkSource)
for theContent in content:
print theContent
except Exception, e:
print str(e)
except Exception,e:
print str(e)
pass
main()
