在Java Selenium WebDriver中使用迭代器

Question

public static boolean FeatureFunctionsCheck(String Feature){
try
{

    Iterator<WebElement> all = (Iterator<WebElement>) Driver.Instance.findElement(By.xpath("//a[contains(text()," + Feature + ")]/ancestor::h3/following-sibling::div/div[@class='navMenu']/p"));

    boolean check = false;
    while(all.hasNext() && check){

        WebElement temp = all.next();
        if(!temp.getText().equals(""))
        {

            Log.Info("Functions: " + temp.getText());
            all = (Iterator<WebElement>) Driver.Instance.findElement(By.xpath("//a[contains(text()," + Feature + ")]/ancestor::h3/following-sibling::div/div[@class='navMenu']/p"));

        }
        else 
            check = true;
    }

    return false;
}
catch(Exception e)
{
    Log.Error("Failed()" + e);
    return false;
}
}

java.lang.ClassCastException: org.openqa.selenium.remote.RemoteWebElement cannot be cast to java.util.Iterator

public static boolean FeatureFunctionsCheck(String Feature){
try
{
    List<WebElement> AllModelFunctions = new ArrayList<WebElement>();


    Log.Info("[Test-235]: Selecting Feature");
    for(WebElement element: AllModelFunctions){
        if(!element.getText().equals(""))
        {   
            Log.Info("Functions: " + element.getText());
        }
    }
    return false;
}
catch(Exception e)
{
    Log.Error("Failed()" + e);
    return false;
}
}

Answer 1

findelement返回一个webelement。您可能要做的是使用findelements搜索给定xpath中的所有元素：

Driver.Instance.findElements(...

而且语法过于复杂。您只需获取列表并遍历它：

List<WebElement> elements = Driver.Instance.findElements(...);
for(WebElement element : elements) {
    if(!element.getText().equals(""))
    {   
        Log.Info("Functions: " + element.getText());
    }
}

顺便说一下，我必须完全相信driver.instance是驱动程序的一个实例（通常在Java中，类实例没有大写，所以我不确定我是否理解正确）。更常见的语法如下：

WebDriver driver = new FirefoxDriver(); // or another browser
driver.findElements(...);
// ...
