Introduction
XPath (XML Path Language) is one of the most powerful ways to locate elements in Selenium WebDriver. It allows us to navigate through HTML and XML documents, making it extremely useful for dynamic web pages where other locators like ID, Name, or CSS fail..
Why is XPath important?
- ✅ Helps locate complex and dynamic elements [What are dynamic elements?]
- ✅ Can traverse the DOM structure (parent, child, siblings) [What is DOM structure?]
- ✅ Works even when attributes are missing or changing
In this guide, we will master XPath step by step with real-world examples!
🔹 What is XPath?
XPath is a query language used to select nodes from an XML document (or an HTML DOM). Selenium WebDriver uses XPath to find web elements efficiently.
There are two types of XPath:
-
1️⃣ Absolute XPath – Starts from the root (
/html/body/div/...) [What is Absolute XPath?]
✅ Example:/html/body/div[1]/section/div/input
-
2️⃣ Relative XPath – Starts from any element using
//[What is Relative XPath?]
✅ Example://input[@id='search-box']
💡 Understanding Single Slash (/) vs. Double Slash (//) in XPath:
| Symbol | Meaning | Example | Explanation |
|---|---|---|---|
/ (Single Slash) |
Absolute XPath | /html/body/div/input |
✅ Selects an element starting from the root of the document. ❌ If any node in the path changes, the XPath will break. |
// (Double Slash) |
Relative XPath | //input[@id='search-box'] |
✅ Searches for the element anywhere in the document. ✅ More flexible and reliable for automation scripts. |
💡 Which one should you use?
- ✅ Relative XPath is preferred because it's shorter, flexible, and more reliable. It will work even if there will be any change in DOM structure of the page.
- ❌ Avoid Absolute XPath unless necessary, as it is long and fragile. It will not work if there will be any change in DOM structure of the page.
✅ Example:
//input[@id='search-box']
🔹 XPath Syntax and Basic Locators
📌 Locating Elements by Attributes
To locate an element using attributes, we use the following syntax:
//tagname[@attribute='value']
✅ Example from Amazon:
Let’s say we want to locate the search box on Amazon's Homepage:
//input[@id='twotabsearchtextbox']
💡 This finds the <input> element where id='twotabsearchtextbox'.
📌 Locating Elements by Text
Sometimes, we need to find elements based on their text content. The syntax for this is:
//tagname[text()='text value']
✅ Example from Wikipedia:
Let’s say we want to find the **"English" language selection link** on Wikipedia's Homepage:
//a[text()='English']
💡 This finds an <a> (anchor/link) element that contains the exact text **"English"**.
💡 When to Use Attribute-Based vs. Text-Based XPath?
- ✅ Use **attribute-based XPath** when an element has **unique and stable attributes** like
id,name, ortype. - ✅ Use **text-based XPath** when elements **do not have reliable attributes** but have unique text.
🔹 XPath Functions & Advanced Techniques
📌 1️⃣ Using contains() Function
The contains() function is used when an attribute value is dynamic or partially known. Instead of searching for an exact match, we can find elements that contain a specific substring.
//tagname[contains(@attribute, 'partial_value')]✅ **Example from Flipkart:**
Locating the **login button** on Flipkart, where the button text contains "Login":
//button[contains(text(),'Login')]
📌 2️⃣ Using starts-with() Function
The starts-with() function is used when the attribute value follows a predictable pattern and always starts with a fixed text.
//tagname[starts-with(@attribute, 'starting_value')]✅ **Example from Amazon:**
Finding the **search box** on Amazon, where the id starts with "twotab":
//input[starts-with(@id, 'twotab')]
🔹 XPath Axes: Navigating the DOM
📌 1️⃣ Child to Parent (parent::)
Sometimes, we need to select the **parent element** of a given child. This is useful when an element doesn’t have a unique attribute but its parent does.
✅ **Syntax:**//childElement/parent::parentElement✅ **Example from Wikipedia:**
Finding the **parent div** of the search input field on Wikipedia:
//input[@id='searchInput']/parent::div
📌 2️⃣ Parent to Child (child::)
To select **child elements** within a parent container, we use the child:: axis.
//parentElement/child::childElement✅ **Example from Amazon:**
Finding the **search button** inside the search container on Amazon:
//span[@id='nav-search-submit-text']/child::input[@type='submit']
📌 3️⃣ Following Sibling (following-sibling::)
If we need to find an element that appears **after** another element at the same level in the DOM, we use following-sibling::.
//referenceElement/following-sibling::siblingElement✅ **Example from a Login Form:**
Finding the **password field** that comes after the email field in a login form:
//div[@id='email_container']/following-sibling::div[@xpath='1']
🔹 How to Find Dynamic Elements Using XPath
Many modern websites have dynamic elements where:
- ❌ IDs change on every page load
- ❌ Elements are generated dynamically
✅ Solution: Use Wildcards & Patterns
You can use the contains() function to handle dynamic attributes.
//*[contains(@id, 'search')]
🔹 This finds any element where the ID contains 'search', even if the rest of the ID is dynamic.
🔹 XPath vs. CSS Selectors: Which One is Better?
| Feature | XPath | CSS Selectors |
|---|---|---|
| Performance | ❌ Slower | ✅ Faster |
| Works with XML? | ✅ Yes | ❌ No |
| Supports Parent Traversal? | ✅ Yes | ❌ No |
| Readability | ❌ Complex | ✅ Simple |
🔹 Use CSS Selectors for performance, but XPath is needed for complex navigations.
🔹 Real-World Examples for XPath Practice
To practice XPath in real-world scenarios, try these websites:
| 🌍 Website | 📌 XPath Example |
|---|---|
| Amazon - Search box | //input[@id='twotabsearchtextbox'] |
| Wikipedia - Search input field | //input[@id='searchInput'] |
| Flipkart - Login button | //button[contains(text(),'Login')] |
🔹 Writing & Testing XPath Easily with SelectorHub
Writing and testing XPath manually can be **time-consuming**. This is where SelectorHub comes in! It is a powerful Chrome extension that helps you **generate, validate, and debug XPath queries effortlessly**.
✅ Why Use SelectorHub?
- Auto-generates **optimized XPath & CSS Selectors**.
- Highlights the **exact element** that matches the XPath query.
- Allows real-time **XPath validation** inside the browser.
- Works even for **dynamic and shadow DOM elements**.
📌 Example: Using SelectorHub to Find XPath for an Amazon Search Box
Let’s see how we can use **SelectorHub** to locate the **Amazon Search Box** XPath:
✅ **Step-by-Step Process:**
- Install **SelectorHub** and open the **Amazon website**.
- Right-click on the **search box** and select **Inspect**.
- Open the **SelectorHub tab** in Developer Tools.
- Copy the generated **optimized XPath**.
//input[@id='twotabsearchtextbox']💡 **Now you can directly use this XPath in Selenium for automation!**
🔹 Best Practices for Writing Efficient XPath
- ✅ Always prefer Relative XPath instead of Absolute XPath
- ✅ Use contains() for dynamic elements
- ✅ Avoid using indexes (
[1]) unless necessary - ✅ Use meaningful attributes (
id,name,placeholder) instead of fragile ones (class,div)
🔹 Conclusion
- 🔹 XPath is a powerful tool for Selenium automation.
- 🔹 You now understand basic and advanced XPath techniques.
- 🔹 The best way to master XPath is through practice!
