Hi everybody,
I'm new to scrapy and I would like to create a scraper returning a list of
urls, (just the urls) in a json format (to be later exported in redis),
belonging to the same domain (ex:www.ilsole24ore.com).
items.py :
from scrapy.item import Item, Field
class Sole24OreItem(Item):
url = Field()
pass
in spiders:
sole.py:
from scrapy.selector import HtmlXPathSelector
from scrapy.contrib.linkextractors.sgml import SgmlLinkExtractor
from scrapy.contrib.spiders import CrawlSpider, Rule
from sole24ore.items import Sole24OreItem
from scrapy.contrib.exporter import JsonLinesItemExporter
class SoleSpider(CrawlSpider):
name = 'sole'
allowed_domains = ['sole24ore.com']
start_urls = ['http://www.sole24ore.com/']
rules = (
Rule(SgmlLinkExtractor(allow=r'Items/'), callback='parse_item',
follow=True),
)
def parse_item(self, response):
l = XPathItemLoader(item=Website(), response=response)
hxs = HtmlXPathSelector(response)
sites = hxs.select('//ul[@class="directory-url"]/li')
items = []
for site in sites:
item = Website()
item['url'] = site.select('a/@href').extract()
items.append(item)
return items
Running scrapy:
sole24ore]$scrapy crawl sole

Any hints to make it work?
