What is the best way to query the ng-model table using xpath in Selenium with Java?

I'm having trouble finding a table from DOCTYPE Html using xpath or className in Selenium/java. I can't seem to locate the locator. How can I retrieve the table using selenium java? Neither of the following paths are effective.

You can view a screenshot of the table at Table screenshot

WebElement tableElement= driver.findElement(By.className("table table-striped"));       
        
WebElement tableElement1 = driver.findElement(By.xpath("/html/body/div[2]/div[2]/div/div/div/div/table/tbody"));

I want to extract all rows in the table through selenium.

The errors I am encountering are:

Exception in thread "main" org.openqa.selenium.NoSuchElementException: no such element: Unable to locate element: {"method":"xpath","selector":"/html/body/div[2]/div[2]/div/div/div/div/table/tbody"}

Exception in thread "main" org.openqa.selenium.NoSuchElementException: no such element: Unable to locate element: {"method":"css selector","selector":".table\.table\-striped"}

Answer №1

That is a thought-provoking question as it sheds light on a commonly overlooked phenomenon in the world of development.

In the present day, our reliance on modern web stacks (yes, even angularjs is still considered modern) exposes us to its intricacies.

It's exciting for users when a page loads in a stylish manner (also known as lazy loaded), where essential resources are loaded first before the rest. You mentioned a table that likely fetches data via an API call and may not render immediately upon page load. While it may seem fast to us humans, the element isn't present initially.

How can you verify this?

Simply go to your page, wait for everything to load properly, right-click, and select view page source. If the table isn't there, it indicates lazy loading, requiring some patience.

What is the solution?

Start by delving into the documentation to fully comprehend the process at hand. Then, utilize a technique outlined there, perhaps resembling the following:

WebElement table = new WebDriverWait(driver, Duration.ofSeconds(3))
                      .until(driver -> driver.findElement(By.cssSelector("table .table-striped")));

While I assume the .table-stripped element resides within a table element, feel free to adjust the selector based on your HTML structure until you pinpoint the correct table.

You may find yourself employing this method more than anticipated, so take the time to educate yourself thoroughly and gain confidence before tackling the next challenge. Happy coding!
