XPath 从子元素中排除文本 [英] XPath Exclude Text From Child Element

问题描述

我正在寻找输出:

 50ml 牛奶

来自以下代码:

<li>50ml <a href="/glossary/milk" class="tooltip-processed">milk<div class="工具提示">
</a>

目前我正在使用 XPATH:

//ul[@class="ingredients-list__group"]/li

但是得到:

50ml 牛奶 Milk mill-k 使用最广泛的成分之一，牛奶通常被称为完整的食物.虽然牛……

如何排除 div/工具提示中的内容?

解决方案

With xpath 2.0:

//ul[@class="ingredients-list__group"]/li/concat(./text()[1], ./a/text()[1])

使用 xpath 1.0:

concat(//ul[@class="ingredients-list__group"]/li/text()[1],//ul[@class="ingredients-list__group"]/li/a/text()[1])'

I'm looking to get the output:

 50ml milk

From the following code:

<ul class="ingredients-list__group">
  <li>50ml <a href="/glossary/milk" class="tooltip-processed">milk
<div class="tooltip">
      <h2
        class="node-title">Milk</h2> <span class="fonetic">mill-k</span>
        <p>One of the most widely used ingredients, milk is often referred to as a complete food. While cow…</p>
        </div>
        </a>
  </li>
</ul>

Currently I'm using the XPATH:

//ul[@class="ingredients-list__group"]/li

But getting:

50ml milk Milk mill-kOne of the most widely used ingredients, milk is often referred to as a complete food. While cow… 

How do I exclude the stuff within the div/tooltip?

解决方案

With xpath 2.0:

//ul[@class="ingredients-list__group"]/li/concat(./text()[1], ./a/text()[1])

With xpath 1.0:

concat(//ul[@class="ingredients-list__group"]/li/text()[1], //ul[@class="ingredients-list__group"]/li/a/text()[1])'
