Extracting Data from XML: The program will prompt for a URL, read the XML data from that URL using urllib and then parse and extract the comment counts from the XML data, compute the sum of the numbers in the file.

py4e_ex_13

from urllib import request
import xml.etree.ElementTree as ET

url = 'http://python-data.dr-chuck.net/comments_24966.xml'
print ("Retrieving", url)
html = request.urlopen(url)
data = html.read()
print("Retrieved",len(data),"characters")

tree = ET.fromstring(data)
results = tree.findall('comments/comment')
icount=len(results)
isum=0

for result in results:
    isum += float(result.find('count').text)
print(icount)
print(isum)
