title: Regular expression double brackets [[text]]
body: <p>I have this regular expression: <code>(?&lt;=\[\[)(.*?)(?=\]\])</code> for finding the pattern <code>[[some text inside]]</code>, and works, but I found a case where doesn't work: <code>[[[ some text]]]</code>.</p>
  
  <p>I'm trying to find a solution, to only finding the pattern with double brackets in both sides like <code>[[]]</code> "exactly".</p>
