package Com.Automation;


import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;

import org.openqa.selenium.firefox.FirefoxDriver;

public class Second_Findelements {

    public static void main(String[] args) {
        WebDriver driver=new FirefoxDriver();
        driver.manage().timeouts().implicitlyWait(50, TimeUnit.SECONDS);
        driver.get("http://www.google.com");
        System.out.println(driver.getCurrentUrl());
        System.out.println(driver.getTitle());

                driver.findElement(By.name("q")).sendKeys("gmail");
        driver.findElement(By.xpath("//a[(text()='Gmail - Google']")).click();
        driver.quit();
    }
}

错误是:

Exception in thread "main" org.openqa.selenium.InvalidSelectorException:
 The given selector //a[(text()='Gmail - Google'] is either invalid or does not result in a WebElement. The following error occurred:

 InvalidSelectorError: Unable to locate an element with the xpath expression //a[(text()='Gmail - Google'] because of the following error:

1 个答案:

答案 0 :(得分:1)

您写错了xpath:

//a[(text()='Gmail - Google']

真正的xpath是:

//a[text()='Gmail - Google']

您已添加额外&#34;(&#34;

如果你想使用contains

//a[contains(text(),'Gmail')]

在上面的xpath

中使用唯一文字而不是Gmail
