Javascript Selenium Webdriver未基于文本、xpath或ID单击菜单项

我在sharepoint中的一个页面中有一些html，看起来非常

<span style="display:none">

<menu type='ServerMenu' id="zz28_RptControls" largeIconMode="true">

<ie:menuitem id="zz29_AddColumn" type="option" iconSrc="/_layouts/images/MenuAddColumn.gif" onMenuClick="window.location = '/SiteDirectory/investment/AE/5539/_layouts/fldNew.aspx?List=%7B49B0DF27%2D5F75%2D4721%2DA81C%2DF8FA9F5CB9DF%7D&amp;Source=http%3A%2F%2Fdv%2Dsharepoint%2Ecollercapital%2Ecom%2FSiteDirectory%2Finvestment%2FAE%2F5539%2FEmails%2FForms%2FAllItems%2Easpx';" text="Create Column" description="Add a column to store additional information about each item." menuGroupId="100"></ie:menuitem>

</ie:menuitem></menu></span><span title="Open Menu">

</div></span>
        </td>

有一个“设置”按钮（ID为zz32\u ListSettingsMenu\t），单击该按钮时，会打开一个包含多个菜单项对象的小下拉框

我可以单击设置对象打开下拉列表，但在Selenium中没有问题，但是当我尝试单击菜单项时，显示没有发生任何事情。我尝试了xpath的

//menuitem[contains（text（），'Document Library Settings']

或ID值的

zz31_ListSettings

甚至

文档库设置的
LINKTEXT
，但似乎没有任何效果，Selenium只是没有找到它来点击它

任何人有什么想法吗？我画的是空白…
显然，通常的方法是首选的，但是如果你被卡住了，你有时可以用手动发送的按键来解决它。我通常使用sendKeys，如下所示：

element.click(); //click on menu to expand it
element.sendKeys( Keys.DOWN ); // key donw once
element.sendKeys( Keys.ENTER); //to select the item

我本来希望避免使用老式的“下，下，左，左，按回车键”爵士乐，但在玩了更长时间后，我想你可能是对的……：（如果我正在录制测试视频，我有时会这样做，我想以后再看。这样做，我可以创建一个看起来更像人类在做的测试。
