How to add row elements in selenium webdriver using java?

Question

I have written code like this

package testpk;
import org.openqa.selenium.By; 
import org.openqa.selenium.WebDriver; 
import org.openqa.selenium.firefox.FirefoxDriver;
import java.util.List;
import org.openqa.selenium.*;
public class Form { 
 public static void main(String[] args) throws InterruptedException { 
 // declaration and instantiation of objects/variables 
 WebDriver driver = new FirefoxDriver();
 driver.manage().window().maximize();
 driver.get("http://beta-app.1bridge.in/#/auth/login"); 
 Thread.sleep(6000);
 driver.findElement(By.xpath("//input[@type='text']")).sendKeys("bbbb",Keys.ENTER);
 Thread.sleep(3000);
 driver.findElement(By.xpath("//input[@type='password']")).sendKeys("123",Keys.ENTER);
 Thread.sleep(7000);
 driver.findElement(By.xpath("//*[@data-id='dashboard']")).click();
 Thread.sleep(5000);
 WebElement table = driver.findElement(By.xpath("#pcoded > div.pcoded-container.navbar-wrapper > div > div > div > div > div > div > app-default > div > app-modal-basic > div > div > div > div > div > div > table > tbody > tr:nth-child(1) > td:nth-child(2)"));
 int intColValue=0;
 int sum=0;
 String strColValue;
 //Loop through all the rows
 for(int i=0;i<rows.size();i++)
 {
 //Get the columns in particular row
 List<WebElement> cols = rows.get(i).findElements(By.tagName("td"));
 //Here I am assuming values are 'String' type
 //Also, I have hard-corded the column number (which you should not do and use column name as input) 
 strColValue = cols.get(2).getText();
 //And convert those to 'Integer'
 intColValue = Integer.parseInt(strColValue);
 //Get the sum
 sum = sum+intColValue;
 }
 System.out.println("Sum: "+sum);
 }
}

It showing error like this Exception in thread "main" java.lang.Error: Unresolved compilation problems:

rows cannot be resolved rows cannot be resolved

at testpk.Form.main(Form.java:38)

enter image description here

I want to add those row elements can anyone please guide me

• chaitra teppad: Can anyone please suggust me
• Alexey R.: Apart from the issue you're facing, here: driver.findElement(By.xpath("#pcoded > div.pcoded-container.navbar-wrapper > div > div > div > div > div > div > app-default > div > app-modal-basic > div > div > div > div > div > div > table > tbody > tr:nth-child(1) > td:nth-child(2)")); you are trying to look up element using xPath locator but provide css locator.
• mrfreester: java is telling you that it doesn't know what rows is because the code doesn't ever create or set a variable named rows that it can see.

Answer 1

Add below line in your code.

This will work for you if you want to sum today's value:-

 driver.findElement(By.xpath("//*[@data-id='dashboard']")).click();
 //this will count all <TR> in your current page.
 List<WebElement> element= driver.findElements(By.tagName("tr"));
 //System.out.println(element.size());
 int integerValue;
 int sumValue=0;
 for(int i=1;i<=element.size()-1;i++)
 {
 //Here enter your Xpath value for the table.
 WebElement todaysValue= driver.findElement(By.xpath("//table[@id='example']//tr["+i+"]/td[2]"));
 String tableValue=todaysValue.getText();
 integerValue=Integer.parseInt(tableValue);
 sumValue=sumValue+integerValue; 
 }
 System.out.println("Total Sum : "+sumValue); 

Also avoid using Thread.sleep in your script this will slow down your script and it's a bad practice, try to use Explicit wait in your script.

Answer 2

Sure.

Add below line before 'for' loop.

List<WebElement> rows = table.findElements(By.tagName("tr"));

This would allow us to get all rows in the table.
