Firepath显示匹配的节点，但不打印

Question

我正试图把价格记录在一个清单上，然后打印出来。但是，执行会在“搜索结果”页面中停止，并且不会打印价格。我认为这是因为Xpath的级别(可能我不是从上层选择？)。我很困惑，因为我已经创建了Xpath，当我在Firepath中使用这个Xpath时，它会选择39个匹配的节点。

提前感谢您的时间和建议。

代码：

import java.util.List;


import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;

public class Flight {

    public static WebDriver driver;

    //This following section is for browser and getting the url
    public static WebDriver browser(){

        driver= new FirefoxDriver();

        driver.get("https://www.orbitz.com/Flights");
        return driver;

    }

    //this following section is getting the properties of the page      
    public static void  getPageProperties(String ff,String ft, String fd, String rd){

        WebElement flyFrom= driver.findElement(By.id("flight-origin"));
        WebElement flyTo= driver.findElement(By.id("flight-destination"));
        WebElement flyDate= driver.findElement(By.id("flight-departing"));
        WebElement returnDate= driver.findElement(By.id("flight-returning"));
        WebElement flight_search_btn= driver.findElement(By.id("search-button"));

        flyFrom.sendKeys(ff);
        flyTo.sendKeys(ft);
        flyDate.sendKeys(fd);
        returnDate.sendKeys(rd);
        flight_search_btn.click();

    }

    // this following section will have the arguments that we will provide for flight search
    public static void testFligthSearch(){

        Flight f= new Flight();
        f.browser();
        f.getPageProperties("MSP", "SEA", "05/01/2017", "05/05/2017");

        List<WebElement> pricelist= driver.findElements(By.xpath("//span[contains(@class,'dollars')]"));

        for(WebElement e: pricelist){

            System.out.println("The prices are: " + e.getText());
        }

    }

    public static void main (String [] args){

        Flight f= new Flight();
        f.testFligthSearch();

    }
}

问题:不印价格。

您正面临此问题，因为尚未加载所有结果，因此必须等待所有搜索结果加载，因此需要等待搜索结果进度栏达到100%，如下所示：

driver.findElement(By.cssSelector("#acol-interstitial = WebElement progressBar > div >div“)；

    WebDriverWait wait = new WebDriverWait(driver, 20);
    wait.until(ExpectedConditions.attributeContains(progressBar, "style", "width: 100%;"));

    List<WebElement> pricelist= driver.findElements(By.cssSelector("ul#flightModuleList  div.offer-price.urgent > span.visuallyhidden"));

    for(WebElement e: pricelist){

        System.out.println("The prices are: " + e.getText());
    }
