<div id="personal">
  <span name="title">Dr.</span>
  <span name="firstname">John</span>
  <span name="lastname">Doe</span>
</div>

JavaScript

const container = document.getElementById('personal');
// Returns the HTMLSpanElement with the name "title" if no such element exists null is returned
const titleSpan = container.children.namedItem('title');
// The following variants return undefined instead of null if there's no element with a matching name or id
const firstnameSpan = container.children['firstname'];
