I have a large table from Wikipedia (from the wiki source), and I want to extract a single column, I have it open in vim, and what I want to extract looks something like this
|col||[[what I want]]||another column||another one||et cetera|
Every line has content I want, so I tried:
:%s/\[\[(.+?)\]\]/\1
But I get the error
E486: Pattern not found: \[\[(.+?)\]\]
