有人能告诉我我做错了什么吗？我试过使用Firebug的xpath的长格式，并且我得到了同样的错误。使用XPathSelenium 2 Webdriver（无法通过xpath找到elemeny）
//span[@onclick=\"mainIframeSrc('l_sams_sched.p_group_schedule')
我能找到的元素和硒IDE点击“Schedule Entry”。问题是，当我尝试在IE中使用webdriver执行相同的操作时。
HTML片段：
<div class="node">
<img alt="Schedule Entry" src="/csui/leaf.gif">
<span class="node-text" onmouseout="this.className='node-text'" onmouseover="this.className='node-text-over'" onclick="mainIframeSrc('l_sams_sched.p_group_schedule')">Schedule Entry</span>
</div>
的webdriver代码：
driver.findElement(By.xpath("//span[@onclick=\"mainIframeSrc('l_sams_sched.p_group_schedule')\"]")).click();
错误：
