java - PhantomJS GhostDriver XPath 不工作

Question

我正在尝试使用 PhantomJS 和 GhostDriver for Java 从 eclipse IDE 运行一个简单的 GoogleSuggest 示例，但是它没有通过 Xpath 找到任何元素，如果我使用其他驱动程序(例如 Firefox)，我可以使用相同的 Xpath 表达式找到元素。有人可以让我知道我在这里做错了什么吗？ GhostDriver 是否支持 Xpath，我是否缺少 Maven 依赖项中的任何内容？

以下行始终返回空列表。

List<WebElement> allSuggestions = driver.findElements(By.xpath("//td[@class='gssb_a gbqfsf']"));`

任何帮助将不胜感激!谢谢。

我的简单类(class)

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;
import org.openqa.selenium.phantomjs.PhantomJSDriver;
import org.openqa.selenium.phantomjs.PhantomJSDriverService;
import org.openqa.selenium.remote.DesiredCapabilities;

    public class GoogleSuggest {
        public static void main(String[] args) throws Exception {
            // The Firefox driver supports javascript 
            //WebDriver driver = new PhantomJSDriver();

            DesiredCapabilities capabilities = DesiredCapabilities.phantomjs();
            capabilities.setCapability(PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY,
                    "/usr/local/bin/phantomjs");                    
            PhantomJSDriver driver = new PhantomJSDriver(capabilities);

            // Go to the Google Suggest home page
            driver.get("http://www.google.com/webhp?complete=1&hl=en");

            // Enter the query string "Cheese"
            WebElement query = driver.findElement(By.name("q"));
            query.sendKeys("Cheese");

            // Sleep until the div we want is visible or 5 seconds is over
            long end = System.currentTimeMillis() + 5000;
            while (System.currentTimeMillis() < end) {
                WebElement resultsDiv = driver.findElement(By.className("gssb_e"));

                // If results have been returned, the results are displayed in a drop down.
                if (resultsDiv.isDisplayed()) {
                  break;
                }
            }

            // And now list the suggestions
            List<WebElement> allSuggestions = driver.findElements(By.xpath("//td[@class='gssb_a gbqfsf']"));

            for (WebElement suggestion : allSuggestions) {
                System.out.println(suggestion.getText());
            }
         }
    }

这可能有效。忽略以前的工具 - 它是我们团队构建的更多内部产品，我们正在将其开源。
