Find an Element Using the Attribute ID in Selenium

We can find an element using the attribute id with Selenium webdriver using the locators - id, css, or xpath. To identify the element with css, the expression should be tagname[id='value'] and the method to be used is By.cssSelector.

To identify the element with xpath, the expression should be //tagname[@id='value']. Then, we have to use the method By.xpath to locate it. To locate an element with locator id, we have to use the By.id method.

Let us look at the html code of an element with id attribute −

Syntax

WebElement e = driver. findElement(By.id("session_key"));
WebElement m = driver. findElement(By.xpath("//input[@id=' session_key']"));
WebElement n =
driver. findElement(By.cssSelector("input[id=' session_key']"));

Example

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import java.util.concurrent.TimeUnit;
public class LocatorId{
   public static void main(String[] args) {
      System.setProperty("webdriver.gecko.driver",
"C:\Users\ghs6kor\Desktop\Java\geckodriver.exe");
      WebDriver driver = new FirefoxDriver();
      //implicit wait
      driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
      //URL launch
      driver.get("https://www.linkedin.com/");
      // identify element with Id
      WebElement l = driver.findElement(By.id("session_key"));
      l.sendKeys("Java");
      //identify element with css
      WebElement m = driver.
      findElement(By.cssSelector("input[id='session_key']"));
      String s = m.getAttribute("value");
      System.out.println("Attribute value: " + s);
      //identify element with xpath
      WebElement n = driver.
      findElement(By.xpath("//input[@id='session_key']"));
      n.clear();
      driver.quit();
   }
}
