We can select the parent tag with the help of Selenium as follows:
driver.findElement(By.xpath("//table[@id='abc']//div/nobr[.='abc']/../.."));
this will help you to find the grandparent of the known Element. Just Remove one (/..) to find the immediate Parent Element.
Like:
driver.findElement(By.xpath("//table[@id='abc']//div/nobr[.='abc']/..));
There are some other ways to implement this, but it worked fine for me.
