Finding Next Sibling Elements in Robot Framework with Selenium

When working with web scraping or automation via Selenium, you may encounter situations where you need to navigate through sibling elements in the DOM. This can especially be the case when you need to extract links from lists of items, such as those contained in <li> tags within a <ul>.

The Challenge

Suppose you have a simple HTML structure like this:

The task is to extract links from the <li> elements sequentially. However, you might run into a problem trying to proceed to the next sibling. The goal is to perform actions based on whether a next sibling exists, ideally without causing errors if the next sibling is not found.

Proposed Solution

To effectively check for the existence of a next sibling in Selenium using Robot Framework, you can create a custom keyword that utilizes JavaScript to evaluate the existence of sibling elements. Here’s how to accomplish this:

Step 1: Create a Custom Keyword

You would create a keyword called Validate child element exists that checks for the existence of a child element within a specified parent. Here’s the syntax for it:

Step 2: Use the Keyword in Your Test Case

Here's how you can use the keyword within your test cases to manage element extraction:

Explanation of the Keyword Functionality

Arguments: The keyword takes two arguments; ${parent} for the parent element, and ${child} for the XPath of the child element.

JavaScript Evaluation: Using window.document.evaluate, it checks if the specified child exists in the context of the parent.

Return Value: If the child is found, it’s returned; otherwise, if not found, the keyword will handle it without causing a test failure.

Practical Application

Extract Links: Start from the first <li> tag and check if the next sibling exists.

Iterate through Siblings: You can loop through siblings, checking for the existence of each before proceeding.

This way, you can ensure that your test handles potential errors gracefully and only performs actions where valid markup exists.

Conclusion

Navigating siblings in the DOM can be complex; however, by creating a custom check in Robot Framework, you can effectively manage this. The method outlined here allows you to ascertain the presence of next sibling elements without facing errors, thus making your automated tests robust and reliable.

By following the implementation steps above, you can streamline your testing process and improve your Selenium-based automation performance.
