在Puppeteer中使用XPath获取元素

const puppeteer = require('puppeteer');

(async () => {
  // 启动浏览器并打开一个新页面
  const browser = await puppeteer.launch();
  const page = await browser.newPage();

  // 导航至目标网址
  await page.goto('https://example.com');

  // 使用XPath选择器查找元素
  const xpathExpression = '//h1[contains(@class, "title")]';
  const [element] = await page.$x(xpathExpression);

  // 输出元素的文本内容
  if (element) {
    const textContent = await page.evaluate(el => el.textContent, element);
    console.log('Element text content:', textContent);
  } else {
    console.log('Element not found');
  }

  // 关闭浏览器
  await browser.close();
})();
