基于scrapy框架爬虫,XPath正确,但是有一项爬不出东西,跪求各位大佬如何解决?

代码如下:

import requests
import scrapy
import bs4
from crawler51job.items import Crawler51JobItem
from scrapy.http import Request
class Spider51jobSpider(scrapy.Spider):     
     name = 'spider51job'
     allowed_domains = ['www.51job.com']
     start_urls = ['https://search.51job.com/list/000000,000000,0000,00,9,99,python,2,1.html']
   def parse(self, response):
        item = Crawler51JobItem()
        item['position'] = response.xpath('//p[@class="t1"]/span/a/@title').extract()
        item['company'] = response.xpath('//span[@class="t2"]/a/@title').extract()
        item['place'] = response.xpath('//div[@class="el"]/span[@class="t3"]/text()').extract()
        item['salary'] = response.xpath('//div[@class="el"]/span[@class="t4"]/text()').extract()
        yield item
        for i in range(2,5):
            url='https://search.51job.com/list/000000,000000,0000,00,9,99,python,2,"+str(i)+".html'
            yield Request(url,callback=self.parse)                      

不知道你这个问题是否已经解决, 如果还没有解决的话:
