and here is my code : public void getLinks()throws Exception{

 try { 

List<WebElement> links = driver.findElements(By.tagName("a")); 

int linkcount = links.size(); 

System.out.println(links.size());

 for (WebElement myElement : links){ 

String link = myElement.getText();

 System.out.println(link); System.out.println(myElement);
if (link !=""){

 myElement.click(); Thread.sleep(2000); System.out.println("third"); 

} //Thread.sleep(5000); 

} }

catch (Exception e){

 System.out.println("error "+e); } }

 Please help

Try this

List<WebElement> componentList = driver.findElements(By.linkText("a"));

for (WebElement component : componentList)

{

   if (component.getAttribute("onclick/href/value").contains("urchoice"))

   {

       component.click();

       break;

[shammi]

Hi Nitin,

               Thanks for for your reply.

But still I am getting same error, loop is running once and next time it's throwing error. If we put break in the end of if condition then loop is running only once.

try {

List<WebElement> componentList = driver.findElements(By.tagName("a"));

System.out.println(componentList.size()); 

 

for (WebElement component : componentList)

{System.out.println(component.getAttribute("href"));

   if (component.getAttribute("href").contains("http://www.google.com/"))

   {

    String link = component.getText(); 

System.out.println(link);

System.out.println(component);

     

       component.click();

       System.out.println("clicked");

      // break;

You are getting a stale element exception because the DOM has changed after you have clicked a link (either because you have been navigated to a new page or reloaded the DOM on the old page).

 

You would need to re-find the element after each click to eliminate the stale element exception.

 

What are you trying to do?

Maybe I’m not being clear, why do you want to click each link?  Do you just want to check the link isn’t dead?

 

If so something like this would be easier:

 

https://github.com/Ardesco/Powder-Monkey/tree/master/src/main/java/com/lazerycode/selenium/urlstatuschecker

 

It’s explained on this blog entry:

i just came here to see how one clicks a lick

[shammi]

Finally I got it, here we go : 

public void getLinks()throws Exception{

try {

List<WebElement> componentList = driver.findElements(By.tagName("a"));

 int numberOfElementsFound = getNumberOfElementsFound(By.tagName("a"));

 for (int pos = 0; pos < numberOfElementsFound; pos++) {

 if (getElementWithIndex(By.tagName("a"), pos).isDisplayed()){

 getElementWithIndex(By.tagName("a"), pos).click();

 }

 }

[Gaurab Pradhan]

Dear Shammi,

I am also facing same as yours,

I have used your code but it shows error on

 if (getElementWithIndex(By.tagName("a"), pos).isDisplayed()){ // it shows error in isDisplayed

 getElementWithIndex(By.tagName("a"), pos).click();  // it shows error in click() method

I am new programmer can you give detail example?? 

[Shammi Kapoor]

Hi Gaurab,

               You have to define getNumberOfElementsFound() and getElementWithIndex() methods.

public int getNumberOfElementsFound(By by) {
        return  driver.findElements(by).size();
      }
     
    public WebElement getElementWithIndex(By by, int pos) {
            return driver.findElements(by).get(pos);
          }

Dear Shammi,

Thanks a lot....

[Diya Sharma]

Hi Shammi,

I saw your post and tried the code:
1) To get all the links of a web page and click them one by one.
I am using Selenium Webdriver.

 Its working for me but i am getting java.lang.IndexOutOfBoundsException error after the loop is executed 11 times.

Code :

import java.util.List;
import org.junit.Before;
import org.junit.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;

public class links1 {

    private WebDriver driver1;
    String siteURL = "https://www.elitmus.com";

    @Before
    public void getLinks1() throws Exception {
        driver1 = new FirefoxDriver();
        driver1.get(siteURL);
    }

    @Test
    public void getLinks() throws Exception {

        try {

            List<WebElement> componentList = driver1.findElements(By

                    .tagName("a"));

            int numberOfElementsFound = getNumberOfElementsFound(By
                    .tagName("a"));

            System.out.println(numberOfElementsFound);

           

            for (int pos = 0; pos < numberOfElementsFound; pos++) {

                if (getElementWithIndex(By.tagName("a"), pos).isDisplayed()) {

                    getElementWithIndex(By.tagName("a"), pos).click();

                    System.out.println("pass");
                    System.out.println(pos);

                } else {
                    System.out.println("fail");
                    System.out.println(pos);
                }

            }
        }

        catch (Exception e) {
            e.printStackTrace();
        }
    }

    public int getNumberOfElementsFound(By by) {
        return driver1.findElements(by).size();

    }

    public WebElement getElementWithIndex(By by, int pos) {

        return driver1.findElements(by).get((int) pos);
    }
}

Hi Diya Sharma,

 

While iterating loop you have to use for loop as :

 

for (int pos = 0; pos < numberOfElementsFound -1; pos++) {

 

instead of

 

for (int pos = 0; pos < numberOfElementsFound; pos++) {

 

Regards,

Panikera

Hi Frnds,

How to get all links and click on specific link on webpage.

Ex: i need to click on 15th link to 20th link only. please help me frnds.

[Karthik Deepan]

This method will you all links added in a given list -->

List<WebElements> allLinks = driver.findElements(By.tagName("a"));

then you can use, allLinks.get(14).click(); to click on the 15th element.

Once you click the link, the webPage will direct to you to the clicked link

The above answer works regardless of the number of entries in the list.

That being said, maybe something like http://home.snafu.de/tilman/xenulink.html would be more helpful to you than Selenium? Depends on what exactly you want to do and why.

I think it should be won't work I think so..

[Karthik Deepan]

What will happen when you click 15th link?

 like     Will the webpage navigate to the new Link?

           Will there be a new window/Tab opened?

           What you want to do after opening those 5 links? What validation is required?

[Rahul Rai]

Hi Shammi,

I am stuck with this same query which i was testing for one of my project and i used your solution above but its not working after some loop count.

Actually my scenario is to find all the active links on a Homepage and then click one link and navigate to the new page and navigate back to home page and click on the next link from the Home Page active list of links.

Could you please share your though and also the code on how i can achieve this.

I am new to Java and I am not getting any solution for my this query anywhere.

Thank you,

Rahul
