How to Fetch an Element Using xPath Based on Another Element's Text

xPath is a powerful language used for queries in XML and HTML documents. One common challenge developers face is finding an element based on the attributes or text of a different element. In this post, we'll explore how to fetch a button element by its aria-labelledby attribute using xPath, given the text of another element.

In this scenario, you need to retrieve the button element based on the text "target 2" of the div with id="ref-1". You have a few attempted xPath queries but haven't been able to achieve the desired results. Let's break down the problem and find a solution together.

Understanding aria-labelledby

The aria-labelledby attribute is used to define a relationship between elements, providing accessibility by linking labels to interactive elements like buttons. This is where 'ref-1' serves as an identifier for our button, but we want to access it through the text "target 2".

The Solution

To successfully fetch the button element using xPath, you can use several methods to effectively achieve this. Let’s explore them below:

Method 1: Direct Reference

This is the most straightforward way, especially when you know the exact id to which aria-labelledby points.
