title: How to match multiple strings, where one is a 'does not contain'?
body: <p>Assume I have a list of strings in memory (basically String1 - String100)</p>
  
  <pre><code>String1
  String2
  ...
  String11
  String12
  ...
  String20
  String21
  ...
  </code></pre>
  
  <p>What is one way, using Regular Expressions, that can do the following?</p>
  
  <p>'Match all strings that do not contain "String1" but do contain "String10" Or "String3"'</p>
