PhantomJS GhostDriver XPath not working

Question

我正在尝试从 eclipse IDE 使用 PhantomJS 和 GhostDriver for Java 运行一个简单的 GoogleSuggest 示例，但是它没有通过 Xpath 找到任何元素，如果我使用另一个驱动程序，如 Firefox，我能够使用相同的 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？Xpath在GhostDriver中是否受支持，我的maven依赖项中是否缺少任何内容？

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。

            //WebDriver driver = new PhantomJSDriver();

            capabilities.setCapability(PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY,

            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。
