title: Regular Expressions: Match words between two given strings (no blank spaces or similar)
body: <p>I am trying to get a regex that is able to get the words, not getting the blank spaces, between two given strings, at this moment I have this one:</p>
  <pre><code>(?&lt;=STR1)(?:\s*)(.*?)(?:\s*)(?=STR2)
  </code></pre>
  <p>I want to use it to get the following results:</p>
  <pre><code>WORD0 STR1    WORD1 WORD2 WORD3  
  WORD4 WORD5 STR2 WORD6
  </code></pre>
  <p>I want a regex that matches <code>WORD1,WORD2,WORD3,WORD4,WORD5</code></p>
  <p>PS: I am working with python, and thank you</p>
