Javascript 获取所有具有相同标签名称的标签值

Question

下面的 javascript 获取 XML 供稿：

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

XML 如下所示：

如何构造一个逗号分隔的字符串，其中包含所有值 author/name 标签？在上面的 XML 中，我想得到 Pablo Dorta-González, Yolanda Santana-Jiménez

Answer 1

可以使用 DOM 查询来获取解析值。请检查下面的代码片段。

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);
