Instapaper-like algorithm

Question

Does anyone of an algorithm that extracts contents from a webpage? like instapaper?

Answer 1

If you just want all the content and none of the formatting in Python

>>> from BeautifulSoup import BeautifulSoup
>>> from urllib import urlopen
>>> soup = BeautifulSoup(urlopen("http://www.python.org/").read())
>>> contents = ''.join(soup.findAll(text=True))

does the trick
