title: python remove specific groups from matching regex
body: <p>I want to remove single groups that are simply dots or commas from the full matching. I'm using:</p>
  <p><code>([\d\[.|,]+)</code></p>
  <p>It extracts:</p>
  <p><code>28 Filmtbl. (N1) 0.5% mg/160% mg/12,5 mg</code></p>
  <pre><code>28
  .
  1
  0.5
  160
  12,5
  </code></pre>
  <p>And I want to have:</p>
  <pre><code>28
  1
  0.5
  160
  12,5
  </code></pre>
  <p>I can guess it has an easy solution but I'm not reaching it..</p>
