How to do sum of the numbers displayed on webpage in selenium webdriver with java

Question

My Scenario

"Go to: http://www.americangolf.co.uk/golf-clubs/fairway-woods "

Print every link under brand

Every link will have a number in front of it

Find sum of all numbers

Total number of products found is written on the page-"49 Products found"

Verify sum s equal to number of products mentioned

My Code

public class americangolf {
    public static void main(String[] args) 
    {
        WebDriver driver = new FirefoxDriver();
        driver.get("http://www.americangolf.co.uk/golf-clubs/fairway-woods");
        driver.manage().window().maximize();
        driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
        List<WebElement> elem = driver.findElements(By.xpath("//div[@id='secondary']/div[1]/div[3]/div/ul/li/a"));
        for(WebElement li:elem)
        {
            System.out.println(li.getText());
        }

        List<WebElement> elem1 = driver.findElements(By.xpath("//div[@id='secondary']/div[1]/div[3]/div/ul/li/a/span[2]"));

        for(WebElement li1:elem1)
        {
            System.out.println(li1.getText());
        }

        int con= Integer.parseInt(driver.findElement(By.xpath("//div[@id='secondary']/div[1]/div[3]/div/ul/li/a/span[2]")).getText());

        for(int i=0;i<elem1.size();i++)
        {
            int sum = i+con;
            System.out.println("Total is:"+sum);
        }
    }
}

Console output

I am getting the above error while doing the sum of all printed numbers. I don't know how to get rid of it. Any solutions to this?

Answer 1

You are getting the whole string (with the parentheses) to sum.

one solution (definitely not the best one) is to replace this:

int con= Integer.parseInt(driver.findElement(By.xpath("//div[@id='secondary']/div[1]/div[3]/div/ul/li/a/span[2]")).getText());

for this:

int con= Integer.parseInt(driver.findElement(By.xpath("//div[@id='secondary']/div[1]/div[3]/div/ul/li/a/span[2]")).getText().replace("(","").replace(")","");

By doing that, you'll be able to parse as an Integer

Answer 2

Try following:

    public class americangolf {

public static void main(String[] args) 
{
    WebDriver driver = new FirefoxDriver();
        driver.get("http://www.americangolf.co.uk/golf-clubs/fairway-woods");
        driver.manage().window().maximize();
        driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
        List<WebElement> elem = driver.findElements(By.xpath("//div[@class='refinement brand']/descendant::a"));
        for(WebElement li:elem)
        {
            System.out.println(li.getText());
        }

        List<WebElement> elem1 = driver.findElements(By.xpath("//div[@class='refinement brand']/descendant::a/span[2]"));
        int sum = 0;
        for(WebElement li1:elem1)
        {
            System.out.println(li1.getText());
            String s = li1.getText().replace("(", "");
            sum = sum + Integer.parseInt(s.replace(")", ""));
        }


        System.out.println("Total sum is: " + sum);

        int totalAppearingOnPage = Integer.parseInt(driver.findElement(
                By.xpath("//h1[normalize-space(text())='Best Selling Fairway woods']/following::div[@class='results-hits'][1]/span")).
                getText());
        System.out.println("Total appearing on page: " + totalAppearingOnPage);
        driver.quit();
    }
    }

In the above code, I have enhanced the xpaths in order to minimize the impact of UI changes. Let me know, if you have any further queries.
