//Go to a page where link is present
driver.findElement(By.xpath("//div[@id='LftNav']/ul/li[3]/div/ul/li[3]/a/label"))).click();
//Click this link will open up a new tab.
driver.findElement(By.xpath("//tr[2]/td[9]/a")).click();
//Now I have to verify a value present in the New Tab.
For that I have to pass the Control to the New Tab. How can I do it?
