  5.   <p>Here are some random words "Robot, Cat, Swan, Shadow"...</p>
  6.   <button>Say Hello Robot</button>
  7. `;

  9. ///////////
  10.  
  11. // find elements with the word `search`
  12. let els = document.evaluate(
  13.   "//p[contains(., 'search')]",
  14.   document,
  15.   null,
  16.   XPathResult.ANY_TYPE,
  17.   null
  18. );
  19. let el;
  20. while (el = els.iterateNext()) {
  21.   console.log('match "search"', el);
  22. }
