Why Am Getting Unable To Locate Element Error? - selenium

Question

I Have Divided The Xpath into 4 Parts Because in Xpath only one Row Value Changes That is /tr[2] Like that 3,4,5 upto the Path Ends.
public class NewTest {
#Test
public void f() throws InterruptedException
{
System.setProperty("webdriver.chrome.driver", "F:\\New folder\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.get("http://xxxxxxxxxxx/index.aspx");
driver.manage().window().maximize();
WebElement ee= driver.findElement(By.id("ddlstore"));
Select s11 = new Select(ee);
s11.selectByVisibleText("xxxxxx");
String s1 = "/html[1]/body[1]/form[1]/div[5]/center[1]";
String s2 = "/div[1]/table[1]/tbody[1]/tr[";
String s3 ="]";
String s4 = "/td[11]/input[1]";
for(int i=2;i<=99;i++)
{
String finalXpath= s1+s2+i+s3+s4;
driver.findElement(By.xpath(finalXpath)).click();
Thread.sleep(3000);
try {
WebElement e1 = driver.findElement(By
.xpath("//p[#id='skipcount']"));
System.out.println(e1.getText());
WebElement e2 = driver.findElement(By.xpath("/html/body/div[1]/div/div"));
WebElement e3 = driver.findElement(By.xpath("/html/body/div[1]/div/div/div[3]/button[2]"));
Actions a1 = new Actions(driver);
a1.moveToElement(e2).click(e3).build().perform();
} catch (Exception e) {
System.out.println("Can't Click on The Element ");
}
}
The Element is Not Clicking it is Showing an Error , Unable to Locate Element,Xpath
Html Code For The First Xpath Divided into String :
<input type="submit" name="CustomPaging_GridView$ctl02$ff" value="SKIP" onclick="product_skip(this);" id="CustomPaging_GridView_ff_0" class="button2" data-id="12691247570" data-id1="36025">
Html Code For Xpath Which is in Try/Catch Block:
<div class="modal-footer">
<span id="prcid" style="display:none;">processing...</span>
<button type="button" id="skipok" onclick="skipoverall(this)" class="btn btn-primary" data-id="12691247570" data-id1="36025">Ok</button>
<button type="button" class="btn btn-secondary" data-dismiss="modal">Cancel</button>
</div>
Ps : Actually The Doubt is, I Need To Click an Skip Button Which has an Same Xpath For All Button and Each Time When i Click Skip Button an Popup Will Appear in That i Need To Click The Cancel Button

Answer 1

Try this :
int i = 1;
String s2 = "/div[1]/table[1]/tbody[1]/tr[' " +i+ " '];
There is no need of String s3.

Answer 2

Try this:
// you don't need 'e2', instead you hover 'e3' and click on it
WebElement e3 = driver.findElement(By.xpath("/html/body/div[1]/div/div/div[3]/button[2]"));
Actions a1 = new Actions(driver);
a1.moveToElement(e3).click(e3).build().perform();
Suggestion:
String s1 = "/html[1]/body[1]/form[1]/div[5]/center[1]";
String s2 = "/div[1]/table[1]/tbody[1]/tr[";
String s3 ="]";
String s4 = "/td[11]/input[1]";
for(int i=2;i<=99;i++)
{
String finalXpath= s1+s2+i+s3+s4;
can be replaced with:
for(int i=2;i<=99;i++)
{
String finalXpath= "/html[1]/body[1]/form[1]/div[5]/center[1]/div[1]/table[1]/tbody[1]/tr[" + i + "]/td[11]/input[1]";
