[java] How to click a link whose href has a certain substring in Selenium?

The following is a bunch of links <a elements. ONLY one of them has a substring "long" as a value for the attribute href

<a class="c1" href= "very_lpng string" > name1 </a>
<a class="g2" href= "verylong string" > name2 </a>   // The one that I need
<a class="g4" href= "very ling string" > name3 </a>
<a class="g5g" href= "very ng string" > name4 </a>

I need to click the link whose href has substring "long" in it. How can I do this?

PS: driver.findElement(By.partialLinkText("long")).click(); // b/c it chooses by the name

You can do this:

//first get all the <a> elements
List<WebElement> linkList=driver.findElements(By.tagName("a"));

//now traverse over the list and check
for(int i=0 ; i<linkList.size() ; i++)
{
    if(linkList.get(i).getAttribute("href").contains("long"))
    {
        linkList.get(i).click();
        break;
    }
}

in this what we r doing is first we are finding all the <a> tags and storing them in a list.After that we are iterating the list one by one to find <a> tag whose href attribute contains long string. And then we click on that particular <a> tag and comes out of the loop.

use driver.findElement(By.partialLinkText("long")).click();

With the help of xpath locator also, you can achieve the same.

Your statement would be:

driver.findElement(By.xpath(".//a[contains(@href,'long')]")).click();

And for clicking all the links contains long in the URL, you can use:-

List<WebElement> linksList = driver.findElements(By.xpath(".//a[contains(@href,'long')]"));

for (WebElement webElement : linksList){
         webElement.click();
}
