<lang python>import urllib import xml.dom.minidom import re
tasks = {}
x = urllib.urlopen("http://www.rosettacode.org/w/api.php?action=query&list=categorymembers&cmtitle=Category:Programming_Tasks&cmlimit=500&format=xml") x = xml.dom.minidom.parseString(x.read()).getElementsByTagName("cm") x = [i.getAttribute('title').replace(" ","_") for i in x]
for i in x:
y = urllib.urlopen("http://www.rosettacode.org/w/index.php?title=%s&action=raw" % i).read()
y = y.lower()
tasks[i] = y.count("{{header|")
