我有上面的脚本，我想废弃列表中的数据。即在... 我在scrapy中尝试过以下命令，但没有工作。它正在给予＆＃39; []＆＃39;作为输出。
response.css("article div.section-body p").extract() <-- this is giving all info under section body but I want only under section-2
response.css("article div.section-body.section-2 p::text").extract()
response.xpath("//article/*[contains(@id, 'setion-2')]").extract()
请帮我提取。谢谢
答案 0 :(得分：0)
尝试
response.css("article div.section-body#section-2 p::text").extract()
div.section-body#section-2表示选择同时具有等级section-body和ID section-2
请注意，#选择了ID，而.选择了类...因此，您的问题中发布的CSS Selector错误。
