  1. Using XPath in Selenium: All you need to know Copyright © 2023 HeadSpin, Inc. All Rights Reserved.

  2. Introduction Navigating the complex web world as an automation tester aims to ensure the delivery of an application that is bug-free and seamless and offers exceptional user experiences. One common challenge on this journey is locating web elements accurately and efficiently to interact with them. Selenium WebDriver helps identify web elements efficiently with various tools and locators. Today, several enterprises are leveraging XPath owing to its greater flexibility and compatibility with old browsers, making it one of its most powerful and versatile locators.

  3. What is XPath in Selenium? XPath, or XML Path Language, is a language for navigating an XML document and selecting nodes. In the context of Selenium WebDriver, XPath is used as a locator to find web elements on a page. It is a powerful tool that can navigate the webpage's HTML structure, making it extremely useful when other simple locators like ID or class fail to find the elements reliably.

  4. There are primarily two types of XPath used in Selenium: • Absolute XPath Types of XPath in Selenium • Relative XPath Copyright © 2023 HeadSpin, Inc. All Rights Reserved.

  5. Absolute XPath(1/2) It's a direct path from the root element to the desired element. It starts from the root node and ends with the desired node, providing a complete path. However, it's brittle and can break with small changes in the web page's structure. Here's a Selenium XPath example for how you might use an absolute XPath in your Selenium code. Suppose you have the following HTML structure: <html> <body> <div> <p>Hello, world!</p> </div> </body> </html> Copyright © 2023 HeadSpin, Inc. All Rights Reserved.

  6. Absolute XPath(2/2) To find the <p> tag using an absolute XPath, you would start at the root <html> tag and provide the full path to the <p> tag: In this case, the XPath "/html/body/div/p" represents the absolute path from the root <html> tag to the desired <p> tag. In several scenarios, however, absolute XPath is not recommended unless necessary because it's brittle, and any change in the HTML structure may cause your test to fail.

  7. Relative XPath(1/2) It starts from any node and ends with the node you want to select. It's more flexible and preferred in most cases, as it's not affected by changes in other parts of the HTML structure. A relative XPath allows you to locate elements starting from any location within the HTML document, not just the root. The relative XPath expression usually starts with //. Here's an example of using relative XPath in Selenium with Python: ```python from selenium import webdriver # Create a new instance of the Firefox driver driver = webdriver.Firefox() # Navigate to a website driver.get("https://example.com") # Find an element using relative XPath element = driver.find_element_by_xpath("//div[@id='myDiv']/p[2]") # Perform actions on the element element.click() # Close the browser driver.quit( Copyright © 2023 HeadSpin, Inc. All Rights Reserved.

  8. Relative XPath(2/2) In the example mentioned in the previous slide , we first import the necessary modules from the Selenium library. Then, we create a new instance of the Firefox driver and navigate to a website (in this case, "https://example.com"). Next, we find an element using a relative XPath expression. The XPath used in this example selects the second `<p>` element inside a `<div>` element with the id "myDiv". You can modify the XPath expression to suit your specific needs. After finding the element, you can perform various actions on it, such as clicking it, entering text, or retrieving its attributes. Finally, we close the browser using the `quit()` method to clean up and release the resources used by the driver. Using relative XPaths is generally recommended over absolute XPaths because they are more resilient to page structure changes. Copyright © 2023 HeadSpin, Inc. All Rights Reserved.

  9. Types of XPath locators XPath locator by ID XPath locator by class name This locator allows you to identify an element by its id attribute. This locator can identify elements based on their class attribute. XPath locator by name XPath locator by tag name This locator identifies elements by their name attribute. This locator can identify elements by their HTML tag name. XPath locator by text XPath locator using contains This locator identifies elements based on their inner text. This locator can identify elements based on a substring of one of their attribute values. XPath locator using starts-with Path locator using ends-with This locator identifies elements whose attribute values start with a particular string. This locator can identify elements whose attribute values end with a particular string. Copyright © 2023 HeadSpin, Inc. All Rights Reserved.

  10. What is chained XPath in Selenium? Chained XPath in Selenium is a concept where multiple XPaths are used in conjunction to locate an element that might not be uniquely identifiable by a single XPath expression. In other words, instead of writing one absolute XPath, we can separate it into multiple relative XPaths. This approach can be specifically useful when dealing with complex or dynamic web structures where elements are not easily accessible through single, unique identifiers. Chaining XPaths can provide more precision and robustness in element location strategy, thus making the automation scripts more stable. Copyright © 2023 HeadSpin, Inc. All Rights Reserved.

  11. What are XPath Axes? XPath Axes are used for finding dynamic elements when normal XPath element search methods like name, ID, class name, etc., aren't possible. XPath Axes navigate through elements in the XML structure of a webpage. They allow you to locate elements based on their relationship with other elements, like parent, sibling, child, ancestor, or descendant.
