Python - Easiest way to scrape text from list of URLs using BeautifulSoup

What's the easiest way to scrape just the text from a handful of webpages开发者_高级运维 (using a list of URLs) using BeautifulSoup? Is it even possible?

Best, Georgina

import urllib2
import BeautifulSoup
import re

Newlines = re.compile(r'[\r\n]\s+')

def getPageText(url):
    # given a url, get page content
    data = urllib2.urlopen(url).read()
    # parse as html structured document
    bs = BeautifulSoup.BeautifulSoup(data, convertEntities=BeautifulSoup.BeautifulSoup.HTML_ENTITIES)
    # kill javascript content
    for s in bs.findAll('script'):
        s.replaceWith('')
    # find body and extract text
    txt = bs.find('body').getText('\n')
    # remove multiple linebreaks and whitespace
    return Newlines.sub('\n', txt)

def main():
    urls = [
        'http://www.stackoverflow.com/questions/5331266/python-easiest-way-to-scrape-text-from-list-of-urls-using-beautifulsoup',
        'http://stackoverflow.com/questions/5330248/how-to-rewrite-a-recursive-function-to-use-a-loop-instead'
    ]
    txt = [getPageText(url) for url in urls]

if __name__=="__main__":
    main()

It now removes javascript and decodes html entities.

It is perfectly possible. Easiest way is to iterate through list of URLs, load the content, find the URLs, add them to main list. Stop iteration when enough pages are found.

Just some tips:

• urllib2.urlopen for fetching content
• BeautifulSoup: findAll('a') for finding URLs

I know that it is not an answer to your exact question (about BeautifulSoup) but a good idea is to have a look at Scrapy which seems to fit yous needs.
