How do I extract attributes of an element using Selenium WebDriver?

To extract attributes of an element using Selenium WebDriver, you need to first locate the element using one of the WebDriver’s locator strategies (e.g., find_element_by_id, find_element_by_xpath, etc.) and then use the get_attribute() method to retrieve the value of the attribute you are interested in.

Here's how you can do it in both Python and JavaScript:


Assuming you have Python and selenium package installed, and you have the appropriate WebDriver for the browser you want to interact with (e.g., chromedriver for Google Chrome, geckodriver for Firefox), here is an example of how to extract an attribute from an element:

from selenium import webdriver

# Start a new browser session
driver = webdriver.Chrome('/path/to/chromedriver')

# Navigate to the page

# Locate the element
element = driver.find_element_by_id('some-id')

# Get the value of the attribute
attribute_value = element.get_attribute('href')


# Clean up (close the browser)

In this example, we're extracting the href attribute (the URL a link points to) from an element with the ID some-id.

JavaScript (Node.js)

Assuming you have Node.js installed along with the selenium-webdriver package, and appropriate WebDriver, here's how you can extract an attribute in JavaScript:

const { Builder, By } = require('selenium-webdriver');

(async function example() {
    let driver = await new Builder().forBrowser('chrome').build();

    try {
        // Navigate to the page
        await driver.get('');

        // Locate the element
        let element = await driver.findElement('some-id'));

        // Get the value of the attribute
        let attributeValue = await element.getAttribute('href');

    } finally {
        // Clean up (close the browser)
        await driver.quit();

Again, this example retrieves the href attribute from an element identified by the ID some-id.

Note on WebDrivers

To run these examples, you need to have the corresponding WebDriver executables downloaded and either placed in a directory included in your system's PATH environment variable or specified directly in your code (as shown in the Python example with /path/to/chromedriver).

Extracting Multiple Attributes

If you need to extract multiple attributes from the same element, you can call get_attribute multiple times with different attribute names.

Extracting Attributes from Multiple Elements

If you want to extract attributes from multiple elements (e.g., all links on a page), you can use find_elements methods (such as find_elements_by_tag_name) to get a list of elements and iterate over them, extracting attributes as needed.

Handling Exceptions

It’s good practice to handle exceptions that might occur when locating elements or extracting attributes, particularly NoSuchElementException which is thrown when an element cannot be found. In Python, you can handle this with a try-except block, and in JavaScript, you can use try-catch.

from selenium.common.exceptions import NoSuchElementException

    element = driver.find_element_by_id('some-id')
    attribute_value = element.get_attribute('href')
except NoSuchElementException:
    print("Element not found")

In JavaScript:

try {
    let element = await driver.findElement('some-id'));
    let attributeValue = await element.getAttribute('href');
} catch (error) {
    if ( === 'NoSuchElementError') {
        console.log("Element not found");
    } else {
        throw error;

By using these techniques, you can effectively extract attributes from web elements using Selenium WebDriver in both Python and JavaScript.
