Xpath. How to parse specific text?

Question

Parsing

The page contains the following code:

...
<div class="item">
  <a name="111" id="111">
  <div class="header">
    <h2 class="">Заголовок</h2>
    <div class="news-author"> Автор новости</div>
  </div>
  <div class="newsbody"
    <div class="news-text">Текст новости</div>
  </div>
</div>
...

And there are many such blocks on the page of each category. How to correctly compose an XPath to pull out new-author from a block with a specific id value in the a tag?
I use Google Sheets for data collection. I collect headlines, dates are all right.
Plugging in the collection of the news itself. They go in a row and belong to different categories. And when I try to collect the author:

=IMPORTXML(СЦЕПИТЬ("https://domain.tdl";IMPORTXML("https://domain.tdl/categories/"; "//div[@class='news-read-more']/a/@href")); "//div[@class='news-author']")

It collects authors from the first news category. Well, the texts, respectively.
