    time_list = response.xpath('//div[@class="listBox"]/ul[@class="list"]//li/span/text()').extract()
    这个 xpath 我拆分成这样

    for item in response.xpath('//div[@class="listBox"]/ul[@class="list"]//li'):
    time=item.xpath('/span/text').extract()[0]
    title=item.xpath('/a/text()').extract()[0]
    link=item.xpath('/a/@href').extract()[0]
    print(time)
    print(title)
    print(link)

    我这样写的话会报错,如何写才是正确的?

    time=item.xpath('/span/text').extract()[0]
    title=item.xpath('/a/text()').extract()[0]
    link=item.xpath('/a/@href').extract()[0]

    前面的 / 删掉就行了
