Javascript get all tag values with the same tag name

I have the javascript below that fetches an XML feed:

fetch("https://export.arxiv.org/api/query?id_list=1804.10436")
    .then(response => response.text())
    .then(str => new window.DOMParser().parseFromString(str, "text/xml"))

The XML looks like below:

<?xml version="1.0" encoding="UTF-8"?>
<feed xmlns="http://www.w3.org/2005/Atom">
  <link href="http://arxiv.org/api/query?search_query%3D%26id_list%3D1804.10436%26start%3D0%26max_results%3D10" rel="self" type="application/atom+xml"/>

</feed>

How can I construct a comma-separate string that contains all values in author/name tags? In the XML above I want to get Pablo Dorta-González, Yolanda Santana-Jiménez

It is possible to use DOM queries to get the parsed values. Please check below code snippet.

fetch("https://export.arxiv.org/api/query?id_list=1804.10436")
    .then(response => response.text())
    .then(str => new window.DOMParser().parseFromString(str, "text/xml"))
    .then(xml => Array.from(xml.querySelectorAll('author>name')).map(e => e.textContent).join(", "))
    .then(console.log);
