如何在node.js中检索XML标记之间的数据

npm install xml2js

const xml2js = require('xml2js');

// XML数据
const xmlData = `
<bookstore>
  <book category="cooking">
    <title lang="en">Everyday Italian</title>
    <author>Giada De Laurentiis</author>
    <year>2005</year>
    <price>30.00</price>
  </book>
  <book category="children">
    <title lang="en">Harry Potter</title>
    <author>J.K. Rowling</author>
    <year>2003</year>
    <price>29.99</price>
  </book>
</bookstore>
`;

// 解析XML数据
xml2js.parseString(xmlData, (err, result) => {
  if (err) {
    console.error(err);
    return;
  }

  // 检索XML标记之间的数据
  const books = result.bookstore.book;
  books.forEach((book) => {
    const title = book.title[0];
    const author = book.author[0];
    const year = book.year[0];
    const price = book.price[0];

    console.log('Title:', title);
    console.log('Author:', author);
    console.log('Year:', year);
    console.log('Price:', price);
    console.log('---');
  });
});
