title: Multiline regex to match config block
body: <p>I am having some issues trying to match a certain config block (multiple ones) from a file. Below is the block that I'm trying to extract from the config file:</p>
  
  <pre><code>ap71xx 00-01-23-45-67-89
   use profile PROFILE
   use rf-domain DOMAIN
   hostname ACCESSPOINT
   area inside
  !
  </code></pre>
  
  <p>There are multiple ones just like this, each with a different MAC address. How do I match a config block across multiple lines?</p>
