Please help me out. Design page looks like below:

<div class="menu_bg">
<ul class="menu">
<li id="retrieve"></li>
<li id="scan" class="test"></li>
<li id="import">
<a target="main" href="import/import.aspx" onclick="clickme(this,'import')">Import</a>
</li>
<li id="admin"></li>
<li id="help"></li>
<li style="float: right;"></li>
</ul>
</div>
</body>

unable to find the element
推荐答案
XPath索引器基于1，与大多数其他语言基于0的语言相反.
XPath indexers are 1-based, as opposed to most other languages whereby they are 0-based.
这意味着您实际上是在定位第二个 li元素，而该元素没有anchor元素.
This means you are actually targetting the 2nd li element, which has no anchor element.
所以:
//*[@class='menu_bg']/ul/li[3]/a
但是，这个XPath查询不是很好，而且位置太严格-因此，尽管这个在之上新固定的XPath应该可以起作用，但我还是建议您考虑一下其他事情.
However, this XPath query is not great and is too strict on position - thus although this newly fixed XPath above should work, I'd advise you to think of something else.
