How Can I Select a Specific CSS Class Using XPath?

Selecting a CSS Class with XPath

You are attempting to select a CSS class named .date using XPath. However, your code is not functioning correctly. To understand why and find a solution, let's delve into the intricacies.

XPath does not have a native equivalent for selecting a CSS class. Instead, you need to use a workaround:

//*[contains(concat(" ", normalize-space(@class), " "), " foo ")]

This expression filters for elements that have the desired class name, ensuring that it is precisely matched and not just partially present. The normalize-space function removes leading and trailing whitespace.

Avoid incorrect approaches such as:

//*[@class="foo"]

This expression only matches elements with a single class name, and it is case-sensitive.

//*[contains(@class, "foo")]

This expression matches elements with any class name that includes "foo," even if it is part of a larger class list.

In summary, to select an exact CSS class with XPath, use the aforementioned expression. This method accurately mimics the behavior of the CSS class selector and effectively filters for desired elements.
