How to Solve Selenium Not Identifying Elements in a div-Only Table

Working with web automation tools like Selenium can be a challenging task, especially when dealing with complex HTML structures. One common problem encountered is when Selenium fails to identify elements within a table composed solely of div elements instead of the standard tr and td structure. In this guide, we will explore this issue in detail and provide a helpful solution.

The Problem

Many modern web applications use CSS-driven layouts, where tables and grids are structured using div elements instead of traditional table, tr, and td tags. This can lead to difficulties for Selenium users when trying to extract data—particularly when not all elements are loaded initially.

Understanding the Structure

Consider a table represented by div elements as follows:

When attempting to access any specific row or cell within this structure using either CSS selectors or XPath expressions, you may encounter NoSuchElementException. This is especially true when you have a dynamic loading scenario where additional rows only appear after user interaction such as scrolling.

Steps Taken to Solve the Problem

Initial Attempts with CSS Selector and XPath

In our scenario, we attempted to retrieve values using two methods:

XPath Approach:

However, both approaches resulted in TimeoutException errors, particularly when trying to access certain rows that seemingly existed.

Discovering the Root Cause

After some exploration, the issue was identified: only the initial set of rows was loaded upon the first entry to the webpage, and further content only appeared as the user scrolled down. To effectively access all elements, a scroll action needed to be implemented.

Implementing the Solution

To mitigate the issue, we employed a simple JavaScript command that triggers a scroll to the bottom of the page, loading all necessary rows:

Here is how your complete approach might look incorporating the scrolling solution:

Conclusion

Navigating through a table structure represented by div elements can be challenging with Selenium. Often the problem arises from dynamic content loading, which can be resolved by effectively triggering a scroll to load all elements of interest. With this understanding, you can now tackle similar challenges in your web automation tasks.

Remember, a careful analysis of the HTML structure and its dynamic nature can save you from encountering frustrating exceptions, ensuring a smooth automation experience!
