title: How can I replace a string in parentheses using a regex?
body: <p>I have a string:</p>
  
  <pre><code>HLN (Formerly Headline News)
  </code></pre>
  
  <p>I want to remove everything inside the parens and the parens themselves, leaving only:</p>
  
  <pre><code>HLN
  </code></pre>
  
  <p>I've tried to do this with a regex, but my difficulty is with this pattern:</p>
  
  <pre><code>"(.+?)"
  </code></pre>
  
  <p>When I use it, it always gives me a <code>PatternSyntaxException</code>.  How can I fix my regex?</p>
