How to get html elements with multiple css classes

问题

I know how to get a list of DIVs of the same css class e.g

<div class="class1">1</div>
<div class="class1">2</div>

using xpath //div[@class='class1']

But how if a div have multiple classes, e.g

<div class="class1 class2">1</div>

What will the xpath like then?

回答1:

The expression you're looking for is:

//div[contains(@class, 'class1') and contains(@class, 'class2')]

I highly suggest XPath visualizer, which can help you debug xpath expressions easily. It can be found here:

回答2:

i think this the expression you're looking for is

//div[starts-with(@class, "class1")]/text()

There's a useful python package called cssselect.

from cssselect import CSSSelector CSSSelector('div.gallery').path

Generates a usable XPath:

descendant-or-self::div[@class and contains(concat(' ', normalize-space(@class), ' '), ' gallery ')]

It's very similar to Flynn1179's answer.
