title: Good regular expression for capturing data inside single quotes but only if it prefixed with something?
body: <p>I have a massive amount of text I just need the contents of whats inside the single quotes (excluding the single quotes).</p>
  <p>for example, here's a cutdown version of what I am searching.</p>
  <pre><code>output line from channel: [2021-11-14 15:59:20] config='954'!
  output line from channel: [2021-11-14 15:59:21] DEBUG: job_name='test' disabled=true
  output line from channel: [2021-11-14 15:59:25] DEBUG: job_id='a185' configsized
  </code></pre>
  <p>and I would like to return</p>
  <pre><code>a185
  </code></pre>
  <p>The regular expression I have so far is this, but it returns the jobid='' - as well as the data i required. I tried to use a capture group and I thought you could delete it?</p>
  <p>My regex skills are old and out of touch lol :-)</p>
  <pre><code>(job_id=)'[^']*'
  </code></pre>
  <p>Note that the line has to have <code>DEBUG</code> on it somewhere to match everything.</p>
