XPath offers the ability to dynamically search for elements within a web page, providing the flexibility to customize a locator for optimal performance.
Selenium provides wrappers for various programming languages, enabling users to interact with web elements. Despite the language used, the selector string remains consistent across different programming environments. For example, in Python, one can utilize the “.find_element_by_xpath()” method within the driver class, with the locator string as a standard argument across all supported languages.
Types of XPath in Selenium
XPath is a versatile language utilized to select elements within an HTML page. It enables the precise identification of elements based on various attributes such as ID, CSS Selectors, Name, TagName, and ClassName, among others.
There are two types of Selenium XPath:
Absolute XPath: The Absolute XPath method in Selenium is considered the most basic form of XPath. It is denoted by a single slash ‘/’ and specifies the complete path of an element within the entire Document Object Model (DOM).
Relative XPath: The Relative XPath method in Selenium identifies elements within a webpage. This method enables users to navigate from a specific point within the Document Object Model (DOM), making it adaptable to page updates without requiring the full path. By leveraging Relative XPath, test scripts can maintain robustness and flexibility in responding to changes in the webpage structure. Using Relative XPath, test scripts are more resilient to updates as it does not require the full path of the element, thereby enhancing the robustness of the test scripts.
