title: Regex catch string between two strings, multiple lines
body: <p>I´m working on a *.po file, I´m trying to catch all the text between <code>msgid ""</code> and <code>msgstr ""</code>, not really lucky, never more than one line:</p>
  
  <pre><code>msgid ""
  "%s asdfgh asdsfgf asdfg %s even if you "
  "asdfgdh sentences with no sense. We are not asking  translate "
  "Shakespeare's %s Hamlet %s !. %s testing regex %s "
  "don't require specific industry knowledge. enjoying "
  msgstr ""
  </code></pre>
  
  <p>What I´ve tried:</p>
  
  <pre><code>var myArray = fileContent.match(/msgid ([""'])(?:(?=(\\?))\2.)*?\1/g);
  </code></pre>
  
  <p>Thanks for your help, I´m not really good with regex :(</p>
