Please help me about xpath for selenium

[2010Zanoza2]

I need to get xpath for web elements for selenium. I have firefox 33.1.1, firebug 2.0.6 and firepath plug-in 0.9.7.

I need to see xpath as something like that: IWebElement query = driver.FindElement(By.XPath(".//*[@id='sb_ifc0']"));

But I see the xpath as "html/body/div[1]/div[3]/div[1]/div[1]/div[3]/div/div/div/form/fieldset[2]/div/div/div/div/div[3]/div/input[3]" for the main google search prompt as example.

And the code like:

 try

            {

                IWebElement query = driver.FindElement(By.XPath("html/body/div[1]/div[3]/div[1]/div[1]/div[3]/div/div/div/form/fieldset[2]/div/div/div/div/div[3]/div/input[3]"));   //i've tried to find the google search prompt by xpass

            }

            catch

            {

                System.Windows.Forms.MessageBox.Show("Login field is not found");

            }

gives me an exception....

 

Please help me to solve the problem.
