    <p>The new graph search on facebook lets you search for current employees of a company using query token - <strong>Current Google employees</strong> (for example). </p> <p>I want to scrap the results page (<a href="http://www.facebook.com/search/104958162837/employees/present" rel="nofollow">http://www.facebook.com/search/104958162837/employees/present</a>) via scrapy.</p> <p>Initial problem was facebook allows only a facebook user to access the information, so directing me to login.php. So, before scraping this url, I logged in via scrapy and then this result page. But even though the http response is 200 for this page, it does not scraps any data. The code is as follows : </p> <pre><code>import sys from scrapy.spider import BaseSpider from scrapy.http import FormRequest from scrapy.selector import HtmlXPathSelector from scrapy.contrib.spiders import CrawlSpider, Rule from scrapy.contrib.linkextractors.sgml import SgmlLinkExtractor from scrapy.selector import HtmlXPathSelector from scrapy.item import Item from scrapy.http import Request class DmozSpider(BaseSpider): name = "test" start_urls = ['https://www.facebook.com/login.php']; task_urls = [query] def parse(self, response): return [FormRequest.from_response(response, formname='login_form',formdata={'email':'myemailid','pass':'myfbpassword'}, callback=self.after_login)] def after_login(self,response): if "authentication failed" in response.body: self.log("Login failed",level=log.ERROR) return return Request(query, callback=self.page_parse) def page_parse(self,response): hxs = HtmlXPathSelector(response) print hxs items = hxs.select('//div[@class="_4_yl"]') count = 0 print items </code></pre> <p>What could I have missed or done incorrectly ?</p> <p>Thanks in advance.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
