Python 这个精灵可以刮吗？

我可以用标准的刮痧来刮这个吗？或者我需要用硒吗

html是：

<td class="example"><sprite-svg name="EXAMPLE2"><svg><use 
xlink:href="/spritemap/1_0_30#sprite-EXAMPLE2"></use></svg></sprite-svg></td>

你知道怎么刮吗？

是的。你可以用scrapy来做：

 response.xpath("//td[@class='table__cell--tight race-runners__box']/sprite-svg/@name").getall()

工作刮痕代码：

import scrapy

class Test(scrapy.Spider):
    name = 'Test'
    start_urls = [
        'https://www.thedogs.com.au/racing/gawler/2020-07-07/1/the-bunyip-maiden-stake-pr2-division1']

def parse(self, response):
    return {"nameList": response.xpath("//td[@class='table__cell--tight race-runners__box']/sprite-svg/@name").getall()}

看着桌子，每个svg精灵都在一个“rug_X”类下面

差不多

import scrapy


class RaceSpider(scrapy.Spider):
    name = 'race'
    allowed_domains = ['thedogs.com.au']
    start_urls = ['https://www.thedogs.com.au/racing/gawler/2020-07-07/1/the-bunyip-maiden-stake-pr2-division1']
    item = {}
    def parse(self, response):
        row = response.xpath('//tbody/tr')

        dog = a.xpath('.//td[@class="table__cell--tight race-runners__name"]/div/a/text()').get()
        
        number = a.xpath('.//td[@class="table__cell--tight race-runners__box"]/sprite-svg/@name').get() 
      
        cleaned_num = int(number.replace('rug_',''))
        grade = a.xpath('.//td[@class="race-runners__grade"]/text()').get()

        item = {'grade':grade, 'greyhound':dog,'rug':cleaned_num}
        yield item

您还可以使用带有自定义函数的项加载器来清理得到的响应。

xpath开头有一个点。您还可以共享站点页面url吗？您在控制台$x（“//td[@class='example']）中链接的页面返回空数组。您能检查一下吗？如何确定哪一个是灰狗？谢谢您的回复，我已经用代码更新了我的帖子。当我将您的代码添加到代码中时，您的代码会给我一个列表，我只希望每只灰狗有一个值。我已经编辑了代码，为您提供了图像中带有数字的每只灰狗。这更清楚吗？太完美了！谢谢。
