title: Is there a regular expression to find two different words in a sentence?
body: <p>Is there a regular expression to find two different words in a sentence?  Extra credit for an expression that works in MS Visual Studio 2008 :)</p>
  
  <p>For example:</p>
  
  <pre><code>reg_ex_match(A, B, "A sentence with A and B") = true
  reg_ex_match(C, D, "A sentence with A and B") = false
  </code></pre>
