Find element by XPath in Selenium Python - Cheat Sheet & Quick Revision

Recall & Review

What is XPath in Selenium?

XPath is a language used to locate elements on a web page by navigating through the HTML structure.

beginner

How do you find an element by XPath in Selenium with Python?

Use driver.find_element(By.XPATH, 'your_xpath_here') to locate the element.

What is the difference between absolute and relative XPath?

Absolute XPath starts from the root element and follows the full path, while relative XPath starts from anywhere in the document and is shorter and more flexible.

intermediate

Why should you prefer relative XPath over absolute XPath?

Relative XPath is less fragile and more maintainable because it does not depend on the full path, which can change often.

beginner

Give an example of a valid XPath to find a button with text 'Submit'.

Example: //button[text()='Submit']

Which Selenium method is used to find an element by XPath in Python?

A driver.find_element_by_class_name('class')

B driver.find_element_by_id('id')

C driver.find_element(By.XPATH, 'xpath')

D driver.find_element_by_name('name')

The correct method to find an element by XPath is driver.find_element(By.XPATH, 'xpath').

What does the XPath expression //div[@class='header'] select?

A All elements with id 'header'

B The first div element

C All elements named 'header'

D All div elements with class 'header'

The expression selects all div elements that have a class attribute equal to 'header'.

Which XPath is an example of absolute XPath?

A /html/body/div[1]/div[2]/button

B //button[@id='submit']

C //div[@class='content']//a

D //input[@name='email']

Absolute XPath starts from the root and follows the full path, like /html/body/div[1]/div[2]/button.

Why is relative XPath preferred over absolute XPath?

A It is longer and more detailed

B It is shorter and less likely to break if page structure changes

C It always selects multiple elements

D It requires no attributes

Relative XPath is shorter and more flexible, so it is less likely to break when the page structure changes.

What does the XPath //input[@type='checkbox'] select?

A All input elements with type attribute equal to 'checkbox'

B The first input element

C All elements with class 'checkbox'

D All checkbox elements

It selects all input elements where the type attribute is 'checkbox'.

Explain how to find an element by XPath in Selenium using Python.

Think about the Selenium method and locator type.

Describe the difference between absolute and relative XPath and why one is preferred.

Consider how page changes affect XPath.

Practice

1. What does the following Selenium Python code do?
driver.find_element(By.XPATH, "//button[@id='submit']")

easy

A. Finds the button element by its class name 'submit'

B. Finds all button elements with id 'submit' on the page

C. Clicks the button with id 'submit'

D. Finds the first button element with id 'submit' on the page

Solution

1. Step 1: Understand the method used

   The method find_element returns the first matching element found by the locator.

2. Step 2: Analyze the XPath expression

   The XPath //button[@id='submit'] selects button elements with attribute id='submit'.

3. Final Answer:

   Finds the first button element with id 'submit' on the page -> Option D

4. Quick Check:

   find_element + XPath with id attribute = first matching element [OK]

Hint: find_element finds only the first matching element [OK]

Common Mistakes:

• Confusing find_element with find_elements
• Thinking XPath finds by class instead of id
• Assuming it clicks the element automatically

2. Which of the following is the correct syntax to find an element by XPath in Selenium Python?

easy

A. driver.find_element(By.XPATH, "//div[@class='header']")

B. driver.find_element_by_xpath("//div[@class='header']")

C. driver.find_element(By.CSS_SELECTOR, "//div[@class='header']")

D. driver.find_element(By.ID, "//div[@class='header']")

Solution

1. Step 1: Recall the modern Selenium syntax

   Since Selenium 4, the recommended way is driver.find_element(By.XPATH, xpath_string).

2. Step 2: Check each option

   driver.find_element(By.XPATH, "//div[@class='header']") uses the correct syntax. driver.find_element_by_xpath("//div[@class='header']") is deprecated. Options C and D use wrong locator types for XPath.

3. Final Answer:

   driver.find_element(By.XPATH, "//div[@class='header']") -> Option A

4. Quick Check:

   Use By.XPATH with find_element [OK]

Hint: Use By.XPATH with find_element, not deprecated methods [OK]

Common Mistakes:

• Using deprecated find_element_by_xpath method
• Mixing locator types like CSS_SELECTOR with XPath
• Passing XPath as ID locator

3. What will be the output of this code snippet if the page contains exactly one <input name='search'> element?

element = driver.find_element(By.XPATH, "//input[@name='search']")
print(element.tag_name)

medium

A. input

B. search

C. NoSuchElementException

D. button

Solution

1. Step 1: Understand what find_element returns

   It returns the first matching WebElement for the XPath.

2. Step 2: Check the tag_name property

   The element found is an input tag, so element.tag_name returns "input".

3. Final Answer:

   input -> Option A

4. Quick Check:

   XPath finds input element, tag_name returns 'input' [OK]

Hint: tag_name returns the HTML tag of the found element [OK]

Common Mistakes:

• Confusing attribute value with tag name
• Expecting exception when element exists
• Assuming tag_name returns attribute value

4. What is wrong with this code snippet?

element = driver.find_element(By.XPATH, "//div[@class='content']")
print(element.text)

Assume the page has multiple <div class='content'> elements.

medium

A. It will raise NoSuchElementException

B. It only finds the first matching element, ignoring others

C. XPath syntax is incorrect

D. element.text will return None

Solution

1. Step 1: Understand find_element behavior

   find_element returns only the first matching element, even if multiple exist.

2. Step 2: Analyze the impact

   If multiple div.content exist, only the first is found and printed, others ignored.

3. Final Answer:

   It only finds the first matching element, ignoring others -> Option B

4. Quick Check:

   find_element returns first match only [OK]

Hint: Use find_elements to get all matches, find_element gets first only [OK]

Common Mistakes:

• Expecting find_element to return all matches
• Thinking XPath syntax is wrong
• Assuming element.text returns None if multiple elements exist

5. You want to find a button element with text exactly 'Submit' using XPath in Selenium Python. Which XPath expression is correct to use with driver.find_element(By.XPATH, xpath)?

hard

A. //button[text()!='Submit']

B. //button[contains(text(), 'Submit')]

C. //button[text()='Submit']

D. //button[@text='Submit']

Solution

1. Step 1: Understand XPath text() function

   XPath text()='Submit' matches elements whose text content is exactly 'Submit'.

2. Step 2: Evaluate each option

   //button[text()='Submit'] matches exact text. //button[contains(text(), 'Submit')] matches partial text (not exact). //button[@text='Submit'] is invalid because text is not an attribute. //button[text()!='Submit'] matches elements whose text is not 'Submit'.

3. Final Answer:

   //button[text()='Submit'] -> Option C

4. Quick Check:

   Use text()='value' for exact text match in XPath [OK]

Hint: Use text()='value' for exact text match in XPath [OK]

Common Mistakes:

• Using @text instead of text() function
• Using contains() when exact match needed
• Using != in XPath for positive match
