How to Extract Text from Web Elements Using Selenium in Python

Are you struggling to extract specific content from a web page using Selenium and Python? If you're looking to grab text embedded within HTML elements, like a specific number or text string, you've come to the right place! In this guide, we’ll walk you through the process of extracting content using a practical example.

The Problem: Extracting the Number 33

Imagine you encounter a situation where you need to capture the number "33" from a web page that displays it within a <font> tag. Your main goal is to use Selenium to retrieve this number and store it in a variable for later use in your application. Here’s the HTML snippet that we’ll be working with:

Understanding the HTML Structure

In this example, the number "33" is contained within a <font> tag. The challenge here is to navigate to this element programmatically and extract its text content using Selenium.

The Solution: Using Selenium to Retrieve Text

To successfully extract the number "33", you'll need to follow a straightforward approach using Selenium's capabilities. Here’s a step-by-step breakdown of how to achieve that.

1. Setting Up Your Environment

Before you start coding, make sure you have the following installed in your Python environment:

Selenium library

A web driver compatible with your browser (e.g., ChromeDriver for Chrome)

You can install Selenium using pip:

Note: If you’re using a different browser, adjust accordingly by replacing webdriver.Chrome() with the appropriate driver, such as webdriver.Firefox() for Firefox.

4. Navigate to the Web Page

After setting up the driver, navigate to the target web page where the number "33" is located:

5. Locate the Element Using XPath

Now we will locate the <font> element containing "33". You can use the element's XPATH. Here’s the line of code to accomplish that:

6. Store the Value in a Variable

In the above step, we not only locate the element but also retrieve the text using the .text attribute and store it in a variable called number. At this point, number will contain the string "33".

7. Clean Up

Don’t forget to close the driver at the end of your script to free up resources:
