title: regex - find all occurrences within a string
body: <p>I have a string: "[2-0]>5&amp;&amp;[3-0]&lt;21"</p>
  
  <p>I would like to pull out an array of: 2-0 and 3-0</p>
  
  <p>The resulting array should look like this: ["2-0", "3-0"]</p>
  
  <p>Does anyone know some fancy regex that will do this, or perhaps another method?</p>
