提取scrapy中的类名 [英] Extract class name in scrapy

问题描述

我正在尝试从trustpilot.com上删除评分.

I am trying to scrape rating off of trustpilot.com.

是否可以使用scrapy提取类名?我正在尝试刮除由五个单独的图像组成的评分，但是这些图像属于该评分名称的类，例如，如果评分为2开始，则:

Is it possible to extract a class name using scrapy? I am trying to scrape a rating which is made up of five individual images but the images are in a class with the name of the rating for example if the rating is 2 starts then:

<div class="star-rating count-2 size-medium clearfix">...

如果是3星，则:

<div class="star-rating count-3 size-medium clearfix">...

那么有没有办法假设.css('.star-rating')这样的选择器，我可以抓取count-2或count-3类?

So is there a way I can scrape the class count-2 or count-3 assuming a selector like .css('.star-rating')?

推荐答案

您可以在代码中的某处使用两者的组合:

You could use a combination of both somewhere in your code:

import re

classes = response.css('.star-rating').xpath("@class").extract()
for cls in classes:
    match = re.search(r'\bcount-\d+\b', cls)
    if match:
        print("Class = {}".format(match.group(0))
