如何在xpath中选择除包含li节点的表节点下的节点以外的所有节点？

Question

我有很多表，我想从这些表中选择所有节点，除了那些至少包含li节点的表。

示例：

<table>
<tr><td>all these nodes should match</td></tr>
</table>

<table>
<tr><td><ul><li>all these nodes including table should NOT match</li></ul></td></tr>
</table>

<table>
<tr><td><div>all these nodes should match</div></td></tr>
</table>

Answer 1

XPATH：

/root/table[not(descendant::li)]

XML：

<?xml version="1.0" encoding="UTF-8"?>
<root>
    <table>
        <tr>
            <td>all these nodes should match</td>
        </tr>
    </table>
    <table>
        <tr>
            <td>
                <ul>
                    <li>all these nodes including table should NOT match</li>
                </ul>
            </td>
        </tr>
    </table>
    <table>
        <tr>
            <td>
                <div>all these nodes should match</div>
            </td>
        </tr>
    </table>
</root>
