元素在Firebug中找到但在Selenium中没有

Question

当我在Firebug中检查XPath时，它按预期工作。

我正在尝试的XPath如下：

.//div[Text()='Data Fields']/following::div[contains(@style,'db3a1a10.pn`g')][2]

但是，在Selenium WebDriver中

 ArrayList<WebElement> al = toolActionObject.getAllElementsByXpath(".//div[Text()='Data Fields']/following::div[contains(@style,'db3a1a10.png')][2]");
 System.out.println(al.size());

输出行就像

DEBUG (SeleniumActions.java:91) - Locating elements by By.xpath: *//div[Text()='Data Fields']/following::div[contains(@style,'db3a1a10.png')][2]
DEBUG (SeleniumActions.java:91) - Locating elements by By.xpath: *//div[Text()='Data Fields']/following::div[contains(@style,'db3a1a10.png')][2]

这种冲突行为的原因是什么？

您的XPath中有两个问题。 text()需要写成小写，而'db3a1a10.png'（可能只是示例代码中的错误）不得包含勾号。
