title: curl a url and get only body back not entire html file
body: <p>I have the url <code>mydomain.com/get</code></p>
  
  <p>At that url I serve an <code>index.html</code>.</p>
  
  <p>That <code>index.html</code> looks like this:</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
      &lt;body&gt;
          12345
      &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>I'd like to use bash to return <code>12345</code>. I'm doing this via jenkins so I can't install specific things. I was thinking grep?</p>
  
  <pre><code>curl mydomain.com/get | grep ???
  </code></pre>
