用javascript打印XML

// 创建一个XML字符串
const xmlString = `<books>
  <book>
   <title>Book 1</title>
   <author>Author 1</author>
  </book>
  <book>
   <title>Book 2</title>
   <author>Author 2</author>
  </book>
</books>
`;

// 创建一个DOM解析器
const parser = new DOMParser();

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

// 获取所有的book元素
const books = xmlDoc.getElementsByTagName("book");

// 遍历所有的book元素并打印其标题和作者
for (let i = 0; i< books.length; i++) {
  const title = books[i].getElementsByTagName("title")[0].textContent;
  const author = books[i].getElementsByTagName("author")[0].textContent;
  console.log(`Title: ${title}, Author: ${author}`);
}
