feedparser and Google News
I'm trying to download a corpus of news (to try to do some natural language processing) from Google News using the universal feedparser with python. I really know nothing of XML, I'm just using an example of how to use the feedparser. The problem is that I can't find in the dict I get from the RSS feed the content of the news just the title.
The code I'm currently trying to use is this:
import feedparser
url = 'http://news.google.com.br/news?pz=1&cf=all&ned=us&hl=en&output=rss'
# just some GNews feed - I'll use a specific search later
feed = feedparser.parse(url)
for post in feed.entries:
print post.t开发者_如何学Pythonitle
print post.keys()
The keys I get in this post are just the title, summary, date, etc... there's no content.
Is this some issue with Google News or am I doing anything wrong? Is there a way to do it?
Have you examined the feed from Google News?
There is a root element in each feed which contains a bunch of information and the actual entries dict. Here's a dirty way to see what's available:
import feedparser
d = feedparser.parse('http://news.google.com/news?pz=1&cf=all&ned=ca&hl=en&topic=w&output=rss')
print [field for field in d]
From what we can see we have an entries
field which most likely contains .. news entries! If you:
import pprint
pprint.pprint(entry for entry in d['entries'])
We get some more information :) That will show you all the fields related to each entry in a pretty printed manner (that's what pprint is for)
So, to fetch all the titles of our news entries from this feed:
titles = [entry.title for entry in d['entries']
so, play around with that. Hopefully that's a helpful start
First you need to check out RSS Specification. And here is a feed parser. That should get you started.
