XPath in Selenium WebDriver: Complete Tutorial (hard)

XPath in Selenium WebDriver

• XPath that starts from the middle of the HTML DOM structure is called Relative XPath.
• XPath axes are used to navigate through elements and attributes in Selenium WebDriver.
• XPath expression //@* is used to select nodes based on attributes like ID, Name, and Classname.
• The disadvantage of using Absolute XPath is that it is brittle and prone to breakage if the HTML structure changes.
• XPath expression//*[contains(@attribute, 'partial text')] is used to find elements with partial text in their attributes.
• Relative XPath expression is always preferred in Selenium WebDriver.
• XPath expression//*[@attribute='value'] is used to select elements with a specific attribute value.
• XPath in Selenium is a language used to locate elements in a web page.
• XPath can be used for HTML, XML, and XHTML documents in Selenium.
• XPath is used in Selenium automation when the elements do not have a unique identifier or when the structure of the web page changes dynamically.
• The basic format of XPath in Selenium is //tagname[@attribute='value'].
• The // symbol in XPath represents the descendant axis, which selects nodes that are descendants of the current node.
• The @ symbol in XPath represents the attribute axis, which selects the attribute of the current node.
• Tagname in XPath represents the name of the HTML tag.
• The child axis in XPath selects all children elements of the current node.
• The preceding axis in XPath selects all nodes that come before the current node.
• The following-sibling axis in XPath selects the following siblings of the context node.
• The parent axis in XPath selects the parent of the current node.
• The self axis in XPath selects the current node itself.
• The descendant axis in XPath selects the descendants of the current node.
• Relative XPath is required to find an element on the web page.
• XPath Axes are used to navigate through elements and attributes.
• XPath expression selects nodes based on attributes, elements, and text.
• The purpose of the 'contains' function in XPath is to select nodes that contain a specified text.
• The OR logical operator is used to combine two conditions in an XPath expression.
• In an AND expression in XPath, if one of the conditions is false, the entire expression returns false.
• The 'starts-with' function in XPath is used to select nodes that start with a specified text.
• The 'text()' function in XPath is used to select the text content of a node.
• The 'following' axis in XPath selects all nodes that come after the current node.
• The 'ancestor' axis in XPath selects all ancestors of the current node.
