Question

以下代码在Xpath中生成错误。 xpath用于动态元素，我使用start-with。在运行代码之前我没有收到任何错误，但是在运行它之后，eclipse会产生错误。请帮忙：

package com.TSOne.tcone;
import java.util.List;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;

public class YahooTextSearch {
       public static void main(String[] args) {
         System.setProperty("webdriver.chrome.driver", "/Users/owner/desktop/chromedriver");
         WebDriver driver = new ChromeDriver();
         driver.get("http://www.yahoo.com");
         driver.findElement(By.id("uh-search-box")).sendKeys("selen");
         List<WebElement> list=driver.findElements(By.xpath("//*[starts-with(@id,'yui_3_18_0_3_1528696’)]"));
         System.out.println(list.size());
       }
}

Answer 1

至少，改变

//*[starts-with(@id,'yui_3_18_0_3_1528696’)]
                                         ^

到

//*[starts-with(@id,'yui_3_18_0_3_1528696')]
                                         ^

（用直单引号替换标记的单个引用。）

如果您有其他问题，请详细说明。请注意，//*在XPath中通常是一项代价高昂的操作，特别是在Selenium中 [感谢您提供有用的评论，@cruisepandey] - 如果可能，指定元素名称可以避免潜在的性能问题。

Answer 2

如果您想在搜索框中输入“Selen”文本后获得列表的大小，那么您应该使用下面提到的代码：

      driver.get("http://www.yahoo.com");
      driver.findElement(By.id("uh-search-box")).sendKeys("selen");
      WebDriverWait wait = new WebDriverWait(driver, 60);
      List<WebElement> list=wait.until(ExpectedConditions.presenceOfAllElementsLocatedBy(By.xpath("//div[@class='yui3-aclist-content']//li[contains(@class,'aclist-item')]")));

      System.out.println(list.size());

请注意，您无法使用定位器“ // * [开始 - with（@ id，'yui_3_18_0_3_1528696'）] “因为 yui_3_18_0_3_1528 之后的数字在重新加载页面时正在改变。

要检索 Yahoo搜索 自动建议，您可以使用以下解决方案：

代码块：

System.setProperty("webdriver.gecko.driver", "C:\\Utility\\BrowserDrivers\\geckodriver.exe");
WebDriver driver = new FirefoxDriver();
driver.get("http://www.yahoo.com");
new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.cssSelector("input#uh-search-box"))).sendKeys("selen");
List<WebElement> yahoo_search_auto_suggestions = new WebDriverWait(driver, 20).until(ExpectedConditions.visibilityOfAllElementsLocatedBy(By.cssSelector("ul.yui3-aclist-list li>span")));
for (WebElement suggestion:yahoo_search_auto_suggestions)
    System.out.println(suggestion.getText());

您可以使用此代码执行此操作：

    WebDriver driver = PlayField.getChromeDriver();  
    driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
    driver.navigate().to("https://www.yahoo.com/");
    driver.manage().window().maximize();

    WebElement inputField = driver.findElement(By.id("uh-search-box"));
    inputField.sendKeys("Bye");
    List<String> autoSuggestions = driver.findElements(By.cssSelector("ul[role='listbox'] li span span"))
                                         .stream()
                                         .map(suggestion -> suggestion.getAttribute("innerText"))
                                         .collect(Collectors.toList());
    System.out.println(autoSuggestions);

如果不使用隐式等待，也可以等待选择器元素的可见性＆＃34; ul [role =＆＃39; listbox＆＃39;] li span span＆＃34;

如果您只想使用xpath执行此操作，也可以使用此xpath：＆＃34; // ul [@role =＆＃39; listbox＆＃39;] / li / span / span＆＃34;

希望它对你有用。

public static void main(String[] args) throws InterruptedException {
    //setting gecko driver
    System.setProperty("webdriver.gecko.driver",paste path of the gecko driver");
    System.setProperty("webdriver.firefox.marionette",paste path of the gecko driver");

    WebDriver driver=new FirefoxDriver();
    //launching yahoo 
    driver.get("https://in.yahoo.com/?p=us");
    //Entering text in to the yahoo search text field
    driver.findElement(By.xpath(".//*[@id='uh-search-box']")).sendKeys("selenium");
    Thread.sleep(5000);

    List<WebElement> ele = driver.findElements(By.xpath(".//ul[@class='yui3-aclist-list']/li/span/span"));

    //getting size of the search results from suggestion box
    System.out.println(ele.size());

    //getting text from the suggestion box
    for (WebElement e : ele) {
        System.out.println(e.getText());
    }
}

尝试这种希望能奏效的
