Read feed from sites.

Is a simple example for reading some feed.
I use two functions , first read url and secondary extract data.
This is the code source:

from xml.dom import minidom as dom
import urllib

def fetchPage(url):
    a = urllib.urlopen(url)
    return ''.join(a.readlines())

def extract(page):
    a = dom.parseString(page)
    item2 = a.getElementsByTagName('SendingDate')[0].firstChild.wholeText
    print "DATA ",item2
    item = a.getElementsByTagName('Cube')
    for i in item:
        if i.hasChildNodes() == True:
            e = i.getElementsByTagName('Rate')[10].firstChild.wholeText
            d = i.getElementsByTagName('Rate')[26].firstChild.wholeText
            print "EURO  ",e
            print "DOLAR ",d

if __name__=='__main__':
    page = fetchPage("")

Result is :

DATA  2011-02-03
EURO   4.2609
DOLAR  3.0921
This is all...
