I take it you are removing Wiki-markup from text? Are you sure you want to
keep the first term? It appears that the first term is the article title,
and the second term is the link text. To preserve the actual rendered
text, I think you'd want the latter...
Anyway, try this to preserve the first term:
Find
\[\[([^\]\|]+)(?:\|[^\]]+)?\]\]
Replace
\1
To preserve the second term, you'll need two different substitutions:
Find
\[\[([^\]\|]+)\]\]
Replace
\1
Find
\[\[[^\]\|]+\|([^\]]+)\]\]
Replace
\1

You should either use a more precise character class in place of the
period, as I did above with [^\]], or use a non-greedy quantifier:
\[\[(.+?)(?:\|.+?)\]\]
Each approach has advantages and disadvantages, but either should work in
this case.

One way to do this would be to write a script that performs all the
substitutions. Here's an example in Perl, my own language of choice:
#!perl
# clear the input record separator; targets may be line-wrapped, e.g.
# [[Example Article|an example
# article]]
$/ = undef;
while (<>) {
s/\[\[([^\]\|]+)\]\]/$1/g; # wiki-link with no link text
s/\[\[[^\]\|]+\|([^\]]+)\]\]/$1/g; # wiki-link with custom link text
print;
}
__END__
If you prefer another language (AppleScript is another obvious choice), ask
the list and someone will likely provide an example.
