XPath selectors are a popular method for parsing HTML pages during web scraping, providing a powerful way to navigate through the complexities of web content in NodeJS and Puppeteer environments. Utilizing the page.$x method allows for precise targeting and extraction of data, making it an invaluable tool for developers looking to harness detailed information from websites. In this landscape, the integration of a robust web scraping API becomes essential, offering a streamlined and efficient approach to web scraping. This API not only simplifies the process of finding elements by XPath but also enhances the overall scraping experience by offering advanced features that cater to the needs of modern web scraping tasks. With such technologies at your disposal, achieving comprehensive and accurate data extraction becomes significantly more manageable, enabling you to focus on deriving valuable insights from your web scraping endeavors.
const puppeteer = require('puppeteer');
async function run() {
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto("https://httpbin.dev/html");
// this will always return all found matches as array:
let elements = await page.$x("//p");
// to get element details we need to use the evaluate method
// for text:
let firstText = await elements[0].evaluate(element => element.textContent);
console.log(firstText);
// for other attributes:
await page.goto("https://httpbin.dev/links/10/1");
let linkElements = await page.$x("//a");
let firstLink = await linkElements[0].evaluate(element => element.href);
console.log(firstLink);
browser.close();
}
run();
⚠ Be aware that this command may attempt to find elements before the page has fully loaded if it’s a dynamic javascript page. For more information, see How to wait for a page to load in Puppeteer?
