title: How to escape parenthesis in Perl Regular Expressions?
body: <p>If I have a string such as:</p>
  
  <pre><code> JOURNAL   Yeast 10 (11), 1503-1509 (1994)
  </code></pre>
  
  <p>How do I get the two numbers in the parenthesis( 11 and 1994) ? One way I attempted was using:</p>
  
  <pre><code>/\s+JOURNAL\s+.*\((\d+).*\((\d+))/
  </code></pre>
  
  <p>but this doesn't work. So my two questions:</p>
  
  <ol>
  <li><p>How to escape the parenthesis so I can use match them in the RE ?</p></li>
  <li><p>How to get the above two numbers ?</p></li>
  </ol>
  
  <p>I am doing this in Perl. Thanks for any help !</p>
