Scrapy different pages

But I'm facing a problem. And I ended up getting confused, I decided to return the code in a functional point.

# -*- coding: utf-8 -*-

import scrapy
from mbu2.items import Mbu2Item2
import urlparse
from scrapy.http import Request

class Spider2Spider(scrapy.Spider):
    name = "spider2"
    # allowed_domains = [""]
    start_urls = (
        # 'file:///C:/scrapy/mbu/mbu2/video.html',
        'file:///C:/scrapy/mbu/mbu2/list.htm',
    )

    def parse(self, response):
        # filename = response.url.split("/")[-1] + '.html'
        # with open(filename, 'wb') as f:
            # f.write(response.body)

        # item = Mbu2Item()
        # return item


        posts = response.xpath('/html/body/div/div[2]/div/div[1]/div[2]/ul/li')
        posts.pop(0)
        for post in posts:
            print(post)
            item = Mbu2Item2()
            item['currentitemlist'] = response.url
            item['currentitemlink'] = urlparse.urljoin(response.url,post.xpath('div/div/h2/a/@href').extract()[0].strip())
            item['posttitle'] = post.xpath('div/div/h2/a/text()').extract()[0].strip()
            # print(item['posttitle'])
            item['posturl'] = urlparse.urljoin(response.url,post.xpath('div/div/h2/a/@href').extract()[0].strip())
            item['postautor'] = post.xpath('div/div/div/div[1]/a/text()').extract()[0].strip()
            # print(item['postautorurl'])
            item['postautorurl'] = urlparse.urljoin(response.url,post.xpath('div/div/div/div[1]/a/@href').extract()[0].strip())
            item['postcat'] = post.xpath('div/div/div/div[2]/span/a/text()').extract()[0].strip()
            # print(item['postcaturl'])
            item['postcaturl'] = urlparse.urljoin(response.url,post.xpath('div/div/div/div[2]/span/a/@href').extract()[0].strip())
            # print(item['posttitle'], item['posturl'], item['postautor'], item['postautorurl'])[0].strip()
            # request = Request(item['posturl'],
                      # callback=self.parse_page2)

            # request.meta['item'] = item
            return Request(item['posturl'], meta={'item': item},
                      callback=self.parse_item)
            # return item


    def parse_item(self, response):

        item = response.meta['item']
        item['currentitemlink2'] = response.url
        # item['desc'] = response.xpath('/html/body/div[1]/div/div/div[1]/div[1]/div/div[1]/p/text()').extract()[0].strip()
        item['videosrcembed'] = response.xpath('/html/body/div[1]/div/div/div[1]/div[1]/div[2]/article/iframe/@src').extract()[0].strip()
        item['textcontent'] = response.xpath('/html/body/div[1]/div/div/div[1]/div[1]/div[2]/article/div[1]').extract()[0].strip()
        item['relatedcatlinks'] = response.xpath('/html/body/div[1]/div/div/div[1]/div[1]/div[2]/article/div[2]').extract()[0].strip()
        # filename = response.url.split("/")[-1] + '.html'
        # with open(filename, 'wb') as f:
            # f.write(response.body)

        yield item

Primary Issue

When I roll the spider. It records only 1 item.

I made the modifications in the logic, so he registered 25 items, but did not complete with the second Request.

(I need to add new requests to every read list, add-> start_page-> append (new_url)

But I am not sure how to identify when it closes the cycle of an Item () and when it is parsing a listing.

Can you help me?
