我是Xpath的新手，目前正致力于通过以下链接提取数据：
https://www.ikea.com/us/en/catalog/products/60203330/
如下所示的Xpath会将所有文本值打印为代码段中的代码。
是否有任何额外的XPath可以添加以解压缩javascript文本输出var jProductData？

使用puppeteer nodejs和chrome-browser-headless：
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch({headless: true});
const page = await browser.newPage();
await page.goto('https://www.ikea.com/us/en/catalog/products/60203330/');
const result = await page.evaluate(() => {
return window.jProductData;
});
console.log(JSON.stringify(result, null, 4));
await browser.close();
})();
