title: Filter multiple fields in only one JSONPath expression
body: <p>Given the following input JSON:</p>
  <pre><code>{
    &quot;a&quot;: 1,
    &quot;b&quot;: &quot;some root string&quot;,
    &quot;c&quot;:
    {
      &quot;d&quot;: &quot;some inner string&quot;
    }
    &quot;e&quot;: &quot;ignored field&quot;
  }
  </code></pre>
  <p>Is it possible to obtain the following JSON using a JSONPath expression?</p>
  <pre><code>{
    &quot;a&quot;: 1,
    &quot;b&quot;: &quot;some root string&quot;,
    &quot;d&quot;: &quot;some inner string&quot;
  }
  </code></pre>
  <p>Thank you in advance.</p>
