Question

您好我的Java中的Selenium WebDriver存在问题。当我使用此代码时（不使用element.click();它可以工作）

public static void main(String[] args) {
        try{

            File salida= new File("salidas/Salida.txt");
            FileWriter fw = new FileWriter(salida);
            PrintWriter volcado = new PrintWriter(fw);

        System.setProperty("webdriver.chrome.driver", "path to\\chromedriver.exe");
        WebDriver driver = new ChromeDriver();
        driver.get("http://ranking-empresas.eleconomista.es/REPSOL-PETROLEO.html");


        String name = driver.findElement(By.xpath("//*[@id=\"business-profile\"]/div[17]/div[1]/div[2]/table/tbody/tr[1]/td[2]")).getText(); 
        String obj_soc = driver.findElement(By.xpath("//*[@id=\"business-profile\"]/div[17]/div[1]/div[2]/table/tbody/tr[2]/td[2]")).getText();
        String direcc = driver.findElement(By.xpath("//*[@id=\"business-profile\"]/div[17]/div[1]/div[2]/table/tbody/tr[3]/td[2]")).getText();
        String loc = driver.findElement(By.xpath("//*[@id=\"business-profile\"]/div[17]/div[1]/div[2]/table/tbody/tr[4]/td[2]")).getText();
        String tel = driver.findElement(By.xpath("//*[@id=\"business-profile\"]/div[17]/div[1]/div[2]/table/tbody/tr[5]/td[2]")).getText();
        String url = driver.findElement(By.xpath("//*[@id=\"business-profile\"]/div[17]/div[1]/div[2]/table/tbody/tr[8]/td[2]")).getText();
        String actividad = driver.findElement(By.xpath("//*[@id=\"business-profile\"]/div[17]/div[1]/div[2]/table/tbody/tr[9]/td[2]")).getText();

            volcado.print(name+" "+obj_soc+" "+direcc+" "+loc+" "+tel+" "+url+" "+actividad);      
            volcado.close();
            driver.close();


    }catch(Exception e){

      e.printStackTrace();

    }}

但是当我想通过上一页使用element.click();访问此问题时出现问题：

System.setProperty("webdriver.chrome.driver", "path to\\chromedriver.exe");

 WebDriver driver = new ChromeDriver();
        driver.get("http://ranking-empresas.eleconomista.es/ranking_empresas_nacional.html");

        WebElement element = driver.findElement(By.xpath("//*[@id=\"tabla-ranking\"]/table/tbody/tr[1]/td[7]/a"));
        element.click();

        String name = driver.findElement(By.xpath("//*[@id=\"business-profile\"]/div[17]/div[1]/div[2]/table/tbody/tr[1]/td[2]")).getText(); 
        String obj_soc = driver.findElement(By.xpath("//*[@id=\"business-profile\"]/div[17]/div[1]/div[2]/table/tbody/tr[2]/td[2]")).getText();
        String direcc = driver.findElement(By.xpath("//*[@id=\"business-profile\"]/div[17]/div[1]/div[2]/table/tbody/tr[3]/td[2]")).getText();
        String loc = driver.findElement(By.xpath("//*[@id=\"business-profile\"]/div[17]/div[1]/div[2]/table/tbody/tr[4]/td[2]")).getText();
        String tel = driver.findElement(By.xpath("//*[@id=\"business-profile\"]/div[17]/div[1]/div[2]/table/tbody/tr[5]/td[2]")).getText();
        String url = driver.findElement(By.xpath("//*[@id=\"business-profile\"]/div[17]/div[1]/div[2]/table/tbody/tr[8]/td[2]")).getText();
        String actividad = driver.findElement(By.xpath("//*[@id=\"business-profile\"]/div[17]/div[1]/div[2]/table/tbody/tr[9]/td[2]")).getText();

            volcado.print(name+" "+obj_soc+" "+direcc+" "+loc+" "+tel+" "+url+" "+actividad);      
            volcado.close();




            driver.close();


    }catch(Exception e){

      e.printStackTrace();

    }}

Selenium打开浏览器，但我的变量页面却没有得到xpath的文本。

当您尝试获取文本时，页面上尚未显示数据。在阅读之前等待数据，它应该没问题：

WebDriver driver = new ChromeDriver();
WebDriverWait wait = new WebDriverWait(driver, 10);

driver.get("http://ranking-empresas.eleconomista.es/ranking_empresas_nacional.html");

driver.findElement(By.xpath("//*[@id=\"tabla-ranking\"]/table/tbody/tr[1]/td[7]/a")).click();

// wait for the data to be present
wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("business-profile")));

String name = driver.findElement(By.xpath("//*[@id=\"business-profile\"]/div[17]/div[1]/div[2]/table/tbody/tr[1]/td[2]")).getText(); 
String obj_soc = driver.findElement(By.xpath("//*[@id=\"business-profile\"]/div[17]/div[1]/div[2]/table/tbody/tr[2]/td[2]")).getText();
String direcc = driver.findElement(By.xpath("//*[@id=\"business-profile\"]/div[17]/div[1]/div[2]/table/tbody/tr[3]/td[2]")).getText();
String loc = driver.findElement(By.xpath("//*[@id=\"business-profile\"]/div[17]/div[1]/div[2]/table/tbody/tr[4]/td[2]")).getText();
String tel = driver.findElement(By.xpath("//*[@id=\"business-profile\"]/div[17]/div[1]/div[2]/table/tbody/tr[5]/td[2]")).getText();
String url = driver.findElement(By.xpath("//*[@id=\"business-profile\"]/div[17]/div[1]/div[2]/table/tbody/tr[8]/td[2]")).getText();
String actividad = driver.findElement(By.xpath("//*[@id=\"business-profile\"]/div[17]/div[1]/div[2]/table/tbody/tr[9]/td[2]")).getText();

volcado.print(name+" "+obj_soc+" "+direcc+" "+loc+" "+tel+" "+url+" "+actividad);      
volcado.close();

然而，更清洁的替代方案是使用单个XPath获取所有单元格：

driver.get("http://ranking-empresas.eleconomista.es/ranking_empresas_nacional.html");

driver.findElement(By.xpath("//*[@id=\"tabla-ranking\"]/table/tbody/tr[1]/td[7]/a")).click();

// wait for the data to be present
List<WebElement> cells = wait.until(
  ExpectedConditions.presenceOfAllElementsLocatedBy(
    By.xpath("//h3[.='Datos comerciales de REPSOL PETROLEO SA']/following::tbody[1]/tr/td[2]")));

String name = cells.get(0).getText(); 
String obj_soc = cells.get(1).getText();
String direcc = cells.get(2).getText();
String loc = cells.get(3).getText();
String tel = cells.get(4).getText();
String url = cells.get(7).getText();
String actividad = cells.get(8).getText();

不能用selenium获取文本
