    elmnt = z[i];
    /*search for elements with a certain atrribute:*/
    file = elmnt.getAttribute["w3-include-html"];
    if [file] {
      /* Make an HTTP request using the attribute value as the file name: */
      xhttp = new XMLHttpRequest[];
      xhttp.onreadystatechange = function[] {
        if [this.readyState == 4] {
          if [this.status == 200] {elmnt.innerHTML = this.responseText;}
          if [this.status == 404] {elmnt.innerHTML = "Page not found.";}
          /* Remove the attribute, and call this function once more: */
          elmnt.removeAttribute["w3-include-html"];
          includeHTML[];
        }
      }
      xhttp.open["GET", file, true];
      xhttp.send[];
