为什么我的xpath路径的东西为空值？

用的是scrapy框架

import scrapy


class WzrySpider(scrapy.Spider):
    name = "wzry"
    allowed_domains = ["pvp.qq.com"]
    # start_urls = ["http://pvp.qq.com/"]
    start_urls = ["https://pvp.qq.com/matchdata/teamData.html?league_id=20230001"]

    def parse(self, response):
        # 战队名字路径：//tr[@class="c-table__row"]/td/div/div/span/text()
        # 比赛场次路径：//tr[@class="c-table__row"]/td[3][@class="is-hidden"]/div[@class="cell"]/text()
        # 比赛场次路径：//tr[@class="c-table__row"]/td[3]/div/text()
        # 胜场路径：//tr[@class="c-table__row"]/td[4]/div/text()
        # 胜率：//tr[@class="c-table__row"]/td[5]/div/text()
        tr_list = response.xpath('//tr[@class="c-table__row"]')
        print(tr_list)
        print('----------')







        pass

可以把response打印出来看是否获取到了网页的html。

在浏览器里面确认了吗，确认有class="c-table__row"的tr没
