Node.js XPath示例？

const xpath = require('xpath');
const dom = require('xmldom').DOMParser;

// XML文档
const xml = `
<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文档
const doc = new dom().parseFromString(xml);

// 使用XPath查询节点
const nodes = xpath.select("//book/title", doc);

// 输出查询结果
nodes.forEach(node => {
  console.log(node.textContent);
});
