python feedparser with yahoo weather rss

Question

I'm trying to use feedparser to get some data from yahoos weather rss. It looks like feed parser strips out the yweather namespace data:

http://weather.yahooapis.com/forecastrss?w=24260013&u=c

<yweather:condition  text="Fair" code="34"  temp="23"  date="Wed, 19 May 2010 5:55 pm EDT" />

looks like feedparser is completely ignoring that. is there away to get it?

Answer 1

Here is one way you could get the data using using lxml:

import urllib2
import lxml.etree

url = "http://weather.yahooapis.com/forecastrss?w=24260013&u=c"
doc = lxml.etree.parse( urllib2.urlopen(url) ).getroot()
conditions = doc.xpath('*/*/yweather:condition',
                       namespaces={'yweather': 'http://xml.weather.yahoo.com/ns/rss/1.0'})
try:
    condition=conditions[0]
except IndexError:
    print('yweather:condition not found')
print(condition.items())
# [('text', 'Fair'), ('code', '33'), ('temp', '16'), ('date', 'Wed, 19 May 2010 9:55 pm EDT')]

The section on using xpath with namespaces might be particularly helpful.
