Scrapy - Parsing Data from Multiple Pages


Scrapy - Parsing Data from Multiple Pages

Does that help You are running a loop, but calling return in it. It will prevent the loop from going through all the links. Use yield instead, in the parse() function.
Other than that, I don't get this part:
code :
#converting website from list item to string
website = ''.join(item['website'])
item['website'] = sel.xpath('td[1]/a/@href').extract()[0]
for sel in response.xpath('//table[@class="rightLinks"]/tr'):
    item = PharmaItem()
    item['company_name'] = sel.xpath('td[1]/a/text()').extract()
    item['location'] = sel.xpath('td[2]/text()').extract()
    website = sel.xpath('td[1]/a/@href').extract()
    request = scrapy.Request(website, callback=self.get_DT)
    request.meta['item'] = item
    yield request

wish help you to fix your issue How about this ugly solution?
Define a dictionary (defaultdict(list)) on a pipeline for storing per-site data. In process_item you can just append a dict(item) to the list of per-site items and raise DropItem exception. Then, in close_spider method, you can dump the data to whereever you want.

Any of those help The subsequent requests you make are filtered as offsite, fix your allowed_domains setting:
code :
allowed_domains = ['pro-football-reference.com']

I wish did fix the issue. For getting the next page you need to make a 'POST' request and pass form-data with pageNum as key and number of the page as value. This code gets you first 5 pages and shows response in the browser:
code :
>>> from scrapy.http import FormRequest
>>> url = 'http://www.australianschoolsdirectory.com.au/search-result.php'
>>> for i in range(1, 6):
...     payload={'pageNum': str(i)}
...     r = FormRequest(url, formdata=payload)
...     fetch(r)
...     view(response)
...
