Types of Xpath
Relative Xpath
Absolute Xpath It is the direct way to find the element, but the disadvantage of the
absolute XPath is that if there are any changes made in the path of the
element then that XPath gets failed.
Ex: /html/body/div[1]/section/div[1]/div

Types of Xpath
Relative Xpath
Absolute Xpath For, Relative Xpath the path starts from the middle of the HTML DOM
structure. It starts with the double forward slash (//), which means it can
search the element anywhere at the webpage
Ex: //input[@id=‘ap_email’]
