title: Regex, get entire string between two keywords
body: <p>I'm doing some output parsing where I need to grab a chunk of text from inbetween two words. For instance if I'm parsing the text </p>
  
  <pre><code>"Hi this is an example"
  </code></pre>
  
  <p>I want to be able to specify that my two words are "Hi" and "example", and i will get back the string </p>
  
  <pre><code>" this is an "
  </code></pre>
  
  <p>I know that regular expressions are useful but I'm unfamiliar with them. Any ideas?</p>
