pyquery response.body retrieve div elements

Question

I am trying to write a web crawler using scrapy and PyQuery.The full spider code is as follows.

from scrapy import Spider
from scrapy.spiders import CrawlSpider, Rule
from scrapy.linkextractors import LinkExtractor

class gotspider(CrawlSpider):
        name='gotspider'
        allowed_domains=['fundrazr.com']
        start_urls = ['https://fundrazr.com/find?category=Health']
        rules = [
        Rule(LinkExtractor(allow=('/find/category=Health')), callback='parse',follow=True)
            ] 


def parse(self, response):
    self.logger.info('A response from %s just arrived!', response.url)
    print(response.body)

The web page skeleton

<div id="header">
<h2 class="title"> Township </h2>
<p><strong>Client: </strong> Township<br>
<strong>Location: </strong>Pennsylvania<br>
<strong>Size: </strong>54,000 SF</p>
 </div>

output of the crawler, The crawler fetches the Requesting URL and its hitting the correct web target but the parse_item or parse method is not getting the response. The Response.URL is not printing. I tried to verify this by running the spider without logs scrapy crawl rsscrach--nolog but nothing is printed as logs. The problem is very granular.

How do I get the Client, Location and Size of the attributes ?

Answer 1

I made standalone script with Scrapy which test different methods to get data and it works without problem. Maybe it helps you find your problem.

import scrapy
import pyquery

class MySpider(scrapy.Spider):

    name = 'myspider'

    start_urls = ['https://fundrazr.com/find?category=Health']

    def parse(self, response):
        print('--- css 1 ---')
        for title in response.css('h2'):
            print('>>>', title)

        print('--- css 2 ---')
        for title in response.css('h2'):
            print('>>>', title.extract()) # without _first())
            print('>>>', title.css('a').extract_first())
            print('>>>', title.css('a ::text').extract_first())
            print('-----')

        print('--- css 3 ---')
        for title in response.css('h2 a ::text'):
            print('>>>', title.extract()) # without _first())

        print('--- pyquery 1 ---')
        p = pyquery.PyQuery(response.body)
        for title in p('h2'):
            print('>>>', title, title.text, '<<<') # `title.text` gives "\n"

        print('--- pyquery 2 ---')
        p = pyquery.PyQuery(response.body)
        for title in p('h2').text():
            print('>>>', title)
        print(p('h2').text())

        print('--- pyquery 3 ---')
        p = pyquery.PyQuery(response.body)
        for title in p('h2 a'):
            print('>>>', title, title.text)
