title: Regex: Find multiple matching strings in all lines
body: <p>I'm trying to match multiple strings in <strong>a single line</strong> using regex in Sublime Text 3.<br>
  I want to match all values and replace them with <code>null.</code><br><br>
  Part of the string that I'm matching against:</p>
  
  <pre><code>"userName":"MyName","hiScore":50,"stuntPoints":192,"coins":200,"specialUser":false
  </code></pre>
  
  <p>List of strings that it should match:</p>
  
  <pre><code>"MyName"
  50
  192
  200
  false
  </code></pre>
  
  <p>Result after replacing:</p>
  
  <pre><code>"userName":null,"hiScore":null,"stuntPoints":null,"coins":null,"specialUser":null
  </code></pre>
  
  <p>Is there a way to do this without using <em>sed</em> or any other substitution method, but just by matching the wanted pattern in regex?</p>
