You are encouraged to solve this task according to the task description, using any language you may know.
Sort most popular programming languages based in number of members in Rosetta Code categorys (from http://www.rosettacode.org/w/index.php?title=Special:Categories&limit=500)
Output:
1. 246 - Programming_Tasks 2. 203 - Python 3. 201 - Ada 4. 188 - OCaml 5. 171 - Perl 6. 169 - Java 7. 168 - Haskell 8. 157 - C 9. 141 - Forth 10. 140 - Ruby ...
Filtering wrong results is optional.
Python
<python>import urllib import re
def key1(x):
return int(x.split()[0])

entries = [] for line in a:
match = re.search('>([^<>]*)</a> \((\d+) members?\)', line)
if match:
entries.append(match.group(2) + ' - ' + match.group(1))
for c, line in enumerate(sorted(entries, key=key1, reverse=True)):
print "%3s. %s" % (c+1, line)</python>
