If I have some xml containing things like the following mediawiki markup:

"    ...collected in the 12th century, of which [[Alexander the Great]] was the
  hero, and in which he was represented,
  somewhat like the British [[King
  Arthur|Arthur]]"

what would be the appropriate arguments to something like:
re.findall([[__?__]], article_entry)
I am stumbling a bit on escaping the double square brackets, and getting the proper link for text like: [[Alexander of Paris|poet named Alexander]]
RegExp: \w+( \w+)+(?=]])
input
[[Alexander of Paris|poet named Alexander]]
output
poet named Alexander
input
[[Alexander of Paris]]
output
Alexander of Paris
