What is Xpath

XPath is a syntax used for selecting parts of an XML document

The way XPath describes paths to elements is similar to the way an operating system describes

paths to files

XPath is almost a small programming language; it has functions and expressions

XPath is a W3C standard

Advantage of smart xpath processing

Maintenance is easy Debugging is easy Saves time and energy Reduces the documentation time

Test case to click first chapter driver.findElement(By.xpath(“/html/body/div/table[3]/tbody/tr/td”)).click(); or driver.findElement(By.xpath(“//td[contains(.,'Chapter')][1]”)).click();
