Feedparser supports reading from local files, simply give a (relative) path to the parse command. This is very useful when testing as:
1. It's faster than loading the live feed every time.

3. When you encounter a problem, you can keep testing the same feed data over and over (keeping copies of "interesting" feeds as needed).
For example, when processing a feed from the New York Times Online, I might use the following to load a live feed:
<source lang="python">
feed = feedreader.parse("http://www.nytimes.com/services/xml/rss/nyt/GlobalHome.xml")
</source>
To do this locally, I can first use wget to download the feed (note the -O option to pick the filename to save to):
<source lang="bash">
wget http://www.nytimes.com/services/xml/rss/nyt/GlobalHome.xml -O nytimes.xml
</source>

Feedparser

Feedparser is a Python library that allows you to read RSS feeds. It helps to isolate your code from some of the differences (in format, version) of RSS feeds.

d = feedparser.parse("http://feedparser.org/docs/examples/atom10.xml")
print d.entries


Reading feeds from local files

Feedparser supports reading from local files, simply give a (relative) path to the parse command. This is very useful when testing as:

1. It's faster than loading the live feed every time.
2. You can keep working, even if a feed is unavailable, or you have no network.
3. When you encounter a problem, you can keep testing the same feed data over and over (keeping copies of "interesting" feeds as needed).

For example, when processing a feed from the New York Times Online, I might use the following to load a live feed:

feed = feedreader.parse("http://www.nytimes.com/services/xml/rss/nyt/GlobalHome.xml")


To do this locally, I can first use wget to download the feed (note the -O option to pick the filename to save to):

wget http://www.nytimes.com/services/xml/rss/nyt/GlobalHome.xml -O nytimes.xml


... and then load the feed in python with:

feed = feedreader.parse("nytimes.xml")
