How Can I Select a CSS Class Like '.date' Using XPath?

Selecting the '.date' Class with XPath

When attempting to select specific CSS classes using XPath, you may encounter difficulties. Let's explore a comprehensive solution to achieve this.

XPath lacks an exact equivalent to CSS class selectors. However, to select an individual class like '.date', consider the following expression:

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

This expression effectively isolates any element with the class 'date' by utilizing the following components:

  • //*: Selects all elements in the document.
  • normalize-space(@class): Removes leading and trailing whitespace from the class attribute.
  • contains(): Checks if the modified class attribute contains the string " date ".

By leveraging this solution, you can efficiently select elements based on specific CSS classes, ensuring accurate data retrieval in your XPath queries.
