如何匹配包含特定字符串的属性? [英] How can I match on an attribute that contains a certain string?

问题描述

当属性包含多个单词时，我在按属性选择节点时遇到问题.例如:

这是我的 xpath 表达式:

//*[@class='atag']

该表达式适用于

但不适用于前面的示例.如何选择

?

解决方案

这是一个查找 className 包含 atag 的 div 元素的示例:

//div[contains(@class, 'atag')]

下面是一个查找 className 包含 atag 和 btag 的 div 元素的示例:

//div[contains(@class, 'atag') and contains(@class ,'btag')]

但是，它也会找到部分匹配项，例如 class="catag bobtag".

如果您不想部分匹配，请参阅下面 bobince 的回答.

I am having a problem selecting nodes by attribute when the attributes contains more than one word. For example:

<div class="atag btag" />

This is my xpath expression:

//*[@class='atag']

The expression works with

<div class="atag" />

but not for the previous example. How can I select the <div>?

解决方案

Here's an example that finds div elements whose className contains atag:

//div[contains(@class, 'atag')]

Here's an example that finds div elements whose className contains atag and btag:

//div[contains(@class, 'atag') and contains(@class ,'btag')]

However, it will also find partial matches like class="catag bobtag".

If you don't want partial matches, see bobince's answer below.
