Python and xml

Python is an excellent choice for writing programs that process XML data.
XML's is a simplified subset of the Standard Generalized Markup Language (SGML).
He set of tools helps developers in creating web pages.
This is one simple example which I use with "conky":

from xml.dom import minidom as dom
import urllib2
def fetchPage(url):
a = urllib2.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')[8].firstChild.wholeText
d = i.getElementsByTagName('Rate')[18].firstChild.wholeText
print "EURO ",e
print "DOLAR ",d

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