title: Regex to match surrounding text
body: <p>I need to replace "something[<em>anything</em>]" with "somethingElse(<em>anything</em>)", the tricky part is <em>anything</em> could be anything, and I don't want to replace that. Is it possible to do with regex?</p>
  
  <p>P.S. In real scenario I'd be using PHPStorm to look / replace it. It would help me a lot to show me what to put exactly at the find window.</p>
  
  <p>Thank you!</p>
