Using Relative XPath in Selenium WebDriver for Java

When it comes to automating web applications with Selenium WebDriver, locating web elements accurately is one of the most critical tasks. Among the different locators available (ID, name, class, CSS selector, etc.), XPath is often the most flexible and powerful. In particular, Relative XPath provides a dynamic way to locate elements even when their attributes or positions may change. In this blog, we’ll explore how to use Relative XPath effectively in Selenium WebDriver with Java.


What is XPath?

XPath (XML Path Language) is a query language used to navigate through elements and attributes in an XML or HTML document. Selenium supports two types of XPath:

Absolute XPath: Starts from the root of the document. Example:

html/body/div[1]/div[2]/form/input

Relative XPath: Starts from the current node or context and is more flexible. Example:

//input[@type='text']

Relative XPath is highly recommended in real-time scenarios because it makes scripts more robust and easier to maintain.


Basic Syntax of Relative XPath

The syntax generally follows this pattern:

xpath

//tagname[@attribute='value']

Examples:


//button[@id='loginBtn']


//input[@name='email']


//a[text()='Learn More']

You can also use logical functions like contains(), starts-with(), and and/or conditions for advanced selections.


Using Relative XPath in Selenium WebDriver (Java)

Here’s a simple example of using Relative XPath in a Selenium test:


java


import org.openqa.selenium.By;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.WebElement;

import org.openqa.selenium.chrome.ChromeDriver;


public class RelativeXPathExample {

    public static void main(String[] args) {

        System.setProperty("webdriver.chrome.driver", "path/to/chromedriver");


        WebDriver driver = new ChromeDriver();

        driver.get("https://example.com");


        // Using Relative XPath to find an input element

        WebElement usernameField = driver.findElement(By.xpath("//input[@id='username']"));

        usernameField.sendKeys("myUsername");


        WebElement passwordField = driver.findElement(By.xpath("//input[@type='password']"));

        passwordField.sendKeys("myPassword");


        WebElement loginButton = driver.findElement(By.xpath("//button[@type='submit']"));

        loginButton.click();


        driver.quit();

    }

}

Advanced Relative XPath Techniques

Using contains() Function

Useful when attribute values are dynamic.


xpath

Copy

Edit

//input[contains(@id, 'user')]

Using starts-with() Function

Helps when values start with a common pattern.


xpath

Copy

Edit

//button[starts-with(@name, 'submit')]

Using Text-Based XPath

Locate elements using visible text.


xpath

Copy

Edit

//a[text()='Contact Us']

Navigating Sibling Elements


xpath

Copy

Edit

//label[text()='Username']/following-sibling::input

Parent or Ancestor Selection


xpath

Copy

Edit

//input[@id='email']/parent::div


Best Practices

  • Prefer Relative XPath over Absolute XPath to keep your tests maintainable.
  • Use functions like contains() for dynamic element values.
  • Combine multiple attributes to create a more specific XPath.
  • Avoid overly complex XPath expressions unless absolutely necessary.


Conclusion

Using Relative XPath in Selenium WebDriver for Java is a smart approach to building stable and adaptable automation scripts. It allows you to write XPath expressions that are less prone to break due to UI changes and more aligned with real-world web development practices. With a solid grasp of XPath syntax and functions, you'll be able to tackle even the trickiest web element identification challenges in your Selenium projects.

How to Use Tosca's Test Configuration Parameters

Tosca by Tricentis is a powerful model-based test automation tool widely used in enterprise environments for end-to-end testing. One of its most useful features is Test Configuration Parameters (TCPs), which provide flexibility and control in managing test execution. TCPs enable testers to create reusable test cases by passing dynamic values without hardcoding them. This significantly enhances test maintenance, scalability, and efficiency. In this blog, we’ll explore what Test Configuration Parameters are, how to create and use them, and the best practices to follow when working with TCPs in Tosca. What Are Test Configuration Parameters? Test Configuration Parameters are custom-defined key-value pairs that can be associated with test cases, test case folders, or execution lists in Tosca. They help manage configuration data such as environment URLs, browser types, credentials, or any other variable data that may differ across test runs. By using TCPs, you can avoid duplicating test case...

Using Hibernate ORM for Fullstack Java Data Management

In the world of fullstack Java development, managing data efficiently and seamlessly across the application is critical. One of the most powerful tools in the Java ecosystem for handling database operations is Hibernate ORM (Object-Relational Mapping). Hibernate simplifies the interaction between Java applications and relational databases, reducing boilerplate code and improving maintainability. This blog explores how Hibernate ORM works, why it’s widely used, and how it fits into the data management strategy of a fullstack Java application. What is Hibernate ORM? Hibernate ORM is an open-source Java framework that provides a powerful and flexible mechanism for mapping Java objects to database tables. It abstracts the low-level JDBC code, allowing developers to work with high-level object-oriented concepts. Instead of writing raw SQL queries, Hibernate allows developers to define database interactions using simple Java classes (also known as POJOs) and annotations or XML configurations...
