路径.如何选择两个标签之间的所有文本? [英] Xpath. How to select all text between two tags?

问题描述

这里是html源代码

<div class="text"><a name="dst100030"></a><pre id="p73" class="P"><span class="blk">│Лабораторные методы исследования │</span></pre><pre id="p74" class="P"><span class="blk">├─────────────┬───────────────────────────────┬────────────────────┬──────────────┤</span></pre><a name="dst100031"></a>

我需要获取两个 标签之间的所有文本.我试过的是

response.xpath('//pre//text()[preceding-sibling::a[@name="dst100030"] and following-sibling::a[@name="dst100031"]]')

但它返回空列表.我哪里错了?

解决方案

是

 的兄弟，而不是 text().您可以使用 preceding::a 代替(对于 following 也类似).
Here is the html source code
<div class="text"><a name="dst100030"></a><pre id="p73" class="P"><span class="blk">│Лабораторные методы исследования                                         │</span></pre><pre id="p74" class="P"><span class="blk">├────────────┬───────────────────────────┬─────────────────┬──────────────┤</span></pre><a name="dst100031"></a>
I need to get all text in between the two <a name="dst100030"> tags.
What i tried is 
response.xpath('//pre//text()[preceding-sibling::a[@name="dst100030"] and following-sibling::a[@name="dst100031"]]')
But it returns empty list. Where am I wrong?
解决方案
<a> is a sibling of <pre>, not the text(). You can use preceding::a instead (and similarly for following).
