js 遍历 xml

// 假设我们有以下 XML 字符串
let xmlString = "<books><book><title>JavaScript 教程</title><author>John</author></book><book><title>Java 教程</title><author>Jane</author></book></books>";

// 创建 DOMParser 对象
let parser = new DOMParser();

// 解析 XML 字符串
let xmlDoc = parser.parseFromString(xmlString, "application/xml");

// 获取所有的 book 节点
let books = xmlDoc.getElementsByTagName("book");

// 遍历 book 节点
for (let i = 0; i < books.length; i++) {
  let title = books[i].getElementsByTagName("title")[0].childNodes[0].nodeValue;
  let author = books[i].getElementsByTagName("author")[0].childNodes[0].nodeValue;
  console.log("书名: " + title + ", 作者: " + author);
}
