如何在两个节点之间选择文本 [英] How to select text between two nodes

问题描述

我想使用 Xpath 从网页中选择一些文本，但该文本位于两个节点之间.

I'd like to select some text from a webpage using Xpath, but this text is between two nodes.

...
<table>
    <th>Abbreviation</th>
    <tr>
        <td>
            <span><u>General</u><br/></span>
            My Text <!--The text i want to get-->
            <br/><u>Def</u>
            Some other Text
       </td>
</table>
...

请注意，我无法更改页面，因为它是我无法控制的来源.

Please note that i can't alter the page since it's a source that i can't control.

我已经浏览了 W3C 和维基百科文档，但没有找到任何(或理解的)内容.

I've already been through the W3C and wikipedia docs and dodn't found anything (or understood).

推荐答案

您可以使用以下 XPath 表达式.它搜索带有 u 子元素的 span，然后选择下面的第一个文本.

You can use the following XPath expression. It searches for a span with a u child, then it selects the first following text.

//span[u]/following-sibling::text()[1]
