怎么把这本书的书页都废了

Question

我想删除这个链接的所有页面，http://www.jobisjob.co.uk/search?directUserSearch=true&whatInSearchBox=&whereInSearchBox=london。在

我试过不同的方法，但没有找到解决办法。在

下面是我的代码

import scrapy

    class jobisjobSpider(scrapy.Spider):

        enter code here
        name = 'jobisjob'
        allowed_domains = ['jobisjob.co.uk']

        start_urls = ['http://www.jobisjob.co.uk/search?directUserSearch=true&whatInSearchBox=&whereInSearchBox=london']


        def parse(self, response):

            for sel in response.xpath('//div[@id="ajax-results"]/div[@class="offer_list "]/div[@class="box_offer"]/div[@class="offer"]'):

                item = JobgoItem()
                item['title'] = sel.xpath('strong[@class="title"]/a/text()').extract()
                item['description'] = sel.xpath('p[@class="description"]/text()').extract()
                item['company'] = sel.xpath('p[@class="company"]/span[@itemprop="hiringOrganization"]/a[@itemprop="name"]/text()').extract()
                item['location'] = sel.xpath('p[@class="company"]/span/span[@class="location"]/span/text()').extract()


                yield item

            next_page = response.css("div.wrap paginator results > ul > li > a[rel='nofollow']::attr('href')")
            if next_page:

                url = response.urljoin(next_page[0].extract())
                print "next page: " + str(url)

                yield scrapy.Request(url)

有谁能帮我解决这个问题吗？我对python完全陌生

下一页选择器出错。 您当前的选择器正在搜索名为wrap的标记，然后在div内使用类wrap搜索{}。在

右选择器是

div.wrap.paginator.results > ul > li > a:last-child[rel='nofollow']::attr('href')
