by

Introduction

Selenium and jSoup are two powerful tools that can be used to extract data from a Javascript webpage. Selenium is a web automation tool that can be used to automate web browsers and interact with webpages. jSoup is a Java library that can be used to parse HTML and XML documents. By combining the two tools, it is possible to extract data from a Javascript webpage. This tutorial will provide an overview of how to use Selenium and jSoup to get data from a Javascript webpage.

Solution

The following code can be used to get data from a Javascript webpage using Selenium and jSoup:

// Import the necessary libraries
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;

// Create a new instance of the Chrome driver
WebDriver driver = new ChromeDriver();

// Navigate to the webpage
driver.get(“http://example.com”);

// Get the HTML source code of the page
String pageSource = driver.getPageSource();

// Parse the HTML source code using jSoup
Document doc = Jsoup.parse(pageSource);

// Get the data from the page
String data = doc.select(“#data-element”).text();

// Print the data
System.out.println(data);

// Close the driver
driver.quit();


If you are going to scrape / datamine someone’s site, here are some considerations:

  1. Get permission from the site’s owner! If you do not, you will piss off the owner and get blacklisted in the best case, or be served with a lawsuit in the worst case.
  2. Find out if the site exposes an api. This is always the better way of scraping a site.
  3. Research tools / libraries that are more appropriate for this task. Some of these include curl, wget, httpbuilder, ….. Depending on your level of comfort / knowledge, you may need to research the underlying technologies: http, rest, …..
  4. selenium is a functional test library for browser applications, which makes it a poor choice for this task.

PS: I am fully expecting for this to get downvoted / closed, because discussions / opinions are off-topic for SO.
