I want to scrape the mobile product features from snapdeal.
//*[#id="productSpecs"]/div/div[2]/div[2]/div/table[1]/tbody/tr/td/table/tbody/tr/td[2]
//*[#id="productSpecs"]/div/div[2]/div[2]/div/table[1]/tbody/tr/td/table/tbody/tr/td[1]
these are the xpaths. I can see the results via scraper extention in google chrome.But cant fetch the results through scrapy.
from scrapy.spider import BaseSpider
# from scrapy.selector import HtmlXPathSelector
from scrapy.selector import Selector
from demo.items import CraigslistSampleItem
class MySpider(BaseSpider):
name = "craigs"
allowed_domains = ["www.snapdeal.com"]
start_urls = ["http://www.snapdeal.com/product/samsung-galaxy-j2-8gb/655619199985"]
def parse(self, response):
# hxs = HtmlXPathSelector(response)
sel = Selector(response)
titles = sel.xpath("//*[#id='productSpecs']/div/div[2]/div[2]/div/table[1]/tbody/tr/td/table/tbody/tr/td[2]")
print titles
items = []
for titles in titles:
item = CraigslistSampleItem()
# item["Brand"] = titles.extract()
items.append(item)
print items
titles is prints empty, this is the sample code.
Edit your xpath as:
titles = sel.xpath("//*[#id='productSpecs']/div/div[2]/div[2]/div/table[1]/tr/td/table/tr/td[2]")
This happens because chrome adds extra tbody tag in the source code.

I have scrapy spider and i am using xpath selectors to extract the contents of the page,kindly check where i am going wrong
from scrapy.contrib.loader import ItemLoader
from scrapy.contrib.spiders import CrawlSpider,Rule
from scrapy.selector import HtmlXPathSelector
from medicalproject.items import MedicalprojectItem
from scrapy.contrib.linkextractors.sgml import SgmlLinkExtractor
from scrapy.selector import HtmlXPathSelector
from scrapy import Request
class MySpider(CrawlSpider):
name = "medical"
allowed_domains = ["yananow.org"]
start_urls = ["http://yananow.org/query_stories.php"]
rules = (
Rule(SgmlLinkExtractor(allow=[r'display_story.php\?\id\=\d+']),callback='parse_page',follow=True),
)
def parse_items(self, response):
hxs = HtmlXPathSelector(response)
titles = hxs.xpath('/html/body/div/table/tbody/tr[2]/td/table/tbody/tr/td')
items = []
for title in titles:
item = MedicalprojectItem()
item["patient_name"] = title.xpath("/html/body/div/table/tbody/tr[2]/td/table/tbody/tr/td/img[1]/text()").extract()
item["stories"] = title.xpath("/html/body/div/table/tbody/tr[2]/td/table/tbody/tr/td/div/font/p/text()").extract()
items.append(item)
return(items)
There are a lot of issues with your code so here is a different approach.
I opted against a CrawlSpider to have more control over the scraping process. Especially with grabbing the name from the query page and the story from a detail page.
I tried to simplify the XPath statements by not diving into the (nested) table structures but looking for patterns of content. So if you want to extract a story ... there must be a link to a story.
Here comes the tested code (with comments):
# -*- coding: utf-8 -*-
import scrapy
class MyItem(scrapy.Item):
name = scrapy.Field()
story = scrapy.Field()
class MySpider(scrapy.Spider):
name = 'medical'
allowed_domains = ['yananow.org']
start_urls = ['http://yananow.org/query_stories.php']
def parse(self, response):
rows = response.xpath('//a[contains(#href,"display_story")]')
#loop over all links to stories
for row in rows:
myItem = MyItem() # Create a new item
myItem['name'] = row.xpath('./text()').extract() # assign name from link
story_url = response.urljoin(row.xpath('./#href').extract()[0]) # extract url from link
request = scrapy.Request(url = story_url, callback = self.parse_detail) # create request for detail page with story
request.meta['myItem'] = myItem # pass the item with the request
yield request
def parse_detail(self, response):
myItem = response.meta['myItem'] # extract the item (with the name) from the response
text_raw = response.xpath('//font[#size=3]//text()').extract() # extract the story (text)
myItem['story'] = ' '.join(map(unicode.strip, text_raw)) # clean up the text and assign to item
yield myItem # return the item
I want to scrape data from the site: http://www.consumercomplaints.in/?search=ecom-express#
I am hoping my request is quite simple and straightforward for the more experienced Scrapy users out there.
Problem: I am trying to scrape data for each review.By data,**I mean main title,subtitle ,username,date and review. ** But what i am not able to get the review ,since for review what i want is to goto the link embedded with the main title and then get the whole review not the brief one on the first page and do this for each review.
My spider class:
from scrapy.contrib.spiders import CrawlSpider, Rule
from scrapy.spider import BaseSpider
from scrapy.contrib.linkextractors.sgml import SgmlLinkExtractor
from scrapy.selector import HtmlXPathSelector
from consumercomplaint.items import ConsumercomplaintItem
class MySpider(BaseSpider):
name = "consumer"
allowed_domains = ["http://www.consumercomplaints.in"]
start_urls = ["http://www.consumercomplaints.in/?search=ecom-express&page=11"]
def parse(self, response):
hxs = HtmlXPathSelector(response)
titles = hxs.select('//table[#width="100%"]')
print titles
items = []
del(titles[0])
for i in titles:
item = ConsumercomplaintItem()
item ["maintitle"] = i.select('.//a[1]//text()').extract()
item ["username"] = i.select('.//td[#class="small"]//a[2]/text()').extract()
item["date"]=i.select('.//td[#class="small"]/text()').extract()
item["subtitle"]=i.select('.//td[#class="compl-text"]/div/b[1]/text()').extract()
item["complaint"]=i.select('.//td[#class="compl-text"]/div/text()').extract()
items.append(item)
return items
My item class:
from scrapy.item import Item, Field
class ConsumercomplaintItem(Item):
maintitle = Field()
username = Field()
date = Field()
subtitle = Field()
complaint = Field()
I would do it in two phases:
a) save partial data into item
b) extract link of the full complaint
c) create a new request and save your item into request.meta
d) yield request
a) extract full complaint
b) extract item from meta
c) save complaint into item's field
d) yield item
def parse(self, response):
hxs = HtmlXPathSelector(response)
titles = hxs.select('//table[#width="100%"]')
print titles
items = []
del(titles[0])
for i in titles:
item = ConsumercomplaintItem()
item ["maintitle"] = i.select('.//a[1]//text()').extract()
item ["username"] = i.select('.//td[#class="small"]//a[2]/text()').extract()
item["date"]=i.select('.//td[#class="small"]/text()').extract()
item["subtitle"]=i.select('.//td[#class="compl-text"]/div/b[1]/text()').extract()
complaint_link = row.xpath('//complaint/link/a/#href').extract_first()
complaint_page = response.urljoin(complaint_link)
request = scrapy.Request(cve_page, callback=self.parse_complaint)
request.meta['item'] = item
yield request
def parse_complaint(self, response):
item = response.meta['item']
item['complaint'] = response.xpath('/complaint/path/text()').extract_first()
yield item
I just started learning python / Scrapy. I was able to follow tutorials successfully but I am struggling with a 'test' scraping that I want to do on my own.
What I am trying to do now is go on http://jobs.walmart.com/search/finance-jobs and scrape the job listing.
However, I think I may be doing something wrong in the XPath, but I am not sure what.
There is no "id" for that table, so I am using its class.
from scrapy.spider import BaseSpider
from scrapy.selector import HtmlXPathSelector
class MySpider(BaseSpider):
name = "walmart"
allowed_domains = ["jobs.walmart.com"]
start_urls = ["http://jobs.walmart.com/search/finance-jobs"]
def parse(self, response):
hxs = HtmlXPathSelector(response)
titles = hxs.select("//table[#class='tableSearchResults']")
items = []
for titles in titles:
item = walmart()
item ["title"] = titles.select("a/text()").extract()
item ["link"] = titles.select("a/#href").extract()
items.append(item)
return items
here is what the page source looks like:
The problem as you said also, is your XPATH. It is always useful to run:
scrapy view http://jobs.walmart.com/search/finance-jobs
Before running your spider, to see how the website look like from scrapy view.
This should work now:
from scrapy.spider import BaseSpider
from scrapy.selector import HtmlXPathSelector
class MySpider(BaseSpider):
name = "walmart"
allowed_domains = ["jobs.walmart.com"]
start_urls = ["http://jobs.walmart.com/search/finance-jobs"]
def parse(self, response):
hxs = HtmlXPathSelector(response)
item = walmart()
titles = hxs.select("//table[#class='tableSearchResults']/tr")
items = []
for title in titles:
if title.select("td[#class='td1']/a").extract():
item ["title"] = title.select("td[#class='td1']/a/text()").extract()
item ["link"] = title.select("td[#class='td1']/a/#href").extract()
items.append(item)
return items
So when i try to scrape product review info from epinions.com, if the main review text is too long, it has a "read more" link to another page.
I took an example from "http://www.epinions.com/reviews/samsung-galaxy-note-16-gb-cell-phone/pa_~1" you'll see what i mean if you look at the first review.
I am wondering: is it possible to have a tiny spider in each iteration of the for loop to grab the url and scrape the review out of the new link? I have the following code, but it doesn't work for the tiny "spider".
Here is my code:
from scrapy.spider import BaseSpider
from scrapy.selector import HtmlXPathSelector
from epinions_test.items import EpinionsTestItem
from scrapy.http import Response, HtmlResponse
class MySpider(BaseSpider):
name = "epinions"
allow_domains = ["epinions.com"]
start_urls = ['http://www.epinions.com/reviews/samsung-galaxy-note-16-gb-cell-phone/pa_~1']
def parse(self, response):
hxs = HtmlXPathSelector(response)
sites = hxs.select('//div[#class="review_info"]')
items = []
for sites in sites:
item = EpinionsTestItem()
item["title"] = sites.select('h2/a/text()').extract()
item["star"] = sites.select('span/a/span/#title').extract()
item["date"] = sites.select('span/span/span/#title').extract()
item["review"] = sites.select('p/span/text()').extract()
# Everything works fine and i do have those four columns beautifully printed out, until....
url2 = sites.select('p/span/a/#href').extract()
url = str("http://www.epinions.com%s" %str(url2)[3:-2])
# This url is a string. when i print it out, it's like "http://www.epinions.com/review/samsung-galaxy-note-16-gb-cell-phone/content_624031731332", which looks legit.
response2 = HtmlResponse(url)
# I tried in a scrapy shell, it shows that this is a htmlresponse...
hxs2 = HtmlXPathSelector(response2)
fullReview = hxs2.select('//div[#class = "user_review_full"]')
item["url"] = fullReview.select('p/text()').extract()
# The three lines above works in an independent spider, where start_url is changed to the url just generated and everything.
# However, i got nothing from item["url"] in this code.
items.append(item)
return items
Why item["url"] returns nothing?
Thanks!
You should instantiate a new Request in the callback and pass your item in the meta dict:
from scrapy.http import Request
from scrapy.item import Item, Field
from scrapy.spider import BaseSpider
from scrapy.selector import HtmlXPathSelector
class EpinionsTestItem(Item):
title = Field()
star = Field()
date = Field()
review = Field()
class MySpider(BaseSpider):
name = "epinions"
allow_domains = ["epinions.com"]
start_urls = ['http://www.epinions.com/reviews/samsung-galaxy-note-16-gb-cell-phone/pa_~1']
def parse(self, response):
hxs = HtmlXPathSelector(response)
sites = hxs.select('//div[#class="review_info"]')
for sites in sites:
item = EpinionsTestItem()
item["title"] = sites.select('h2/a/text()').extract()
item["star"] = sites.select('span/a/span/#title').extract()
item["date"] = sites.select('span/span/span/#title').extract()
url = sites.select('p/span/a/#href').extract()
url = str("http://www.epinions.com%s" % str(url)[3:-2])
yield Request(url=url, callback=self.parse_url2, meta={'item': item})
def parse_url2(self, response):
hxs = HtmlXPathSelector(response)
item = response.meta['item']
fullReview = hxs.select('//div[#class = "user_review_full"]')
item["review"] = fullReview.select('p/text()').extract()
yield item
Also see documentation.
Hope that helps.
I am trying to scrape Craigslist classifieds using Scrapy to extract items that are for sale.
I am able to extract date, post title, and post url but am having trouble extracting price.
For some reason the current code extracts all of the prices, but when I remove the // before the price span look up the price field returns as empty.
Can someone please review the code below and help me out?
from scrapy.spider import BaseSpider
from scrapy.selector import HtmlXPathSelector
from craigslist_sample.items import CraigslistSampleItem
class MySpider(BaseSpider):
name = "craig"
allowed_domains = ["craigslist.org"]
start_urls = ["http://longisland.craigslist.org/search/sss?sort=date&query=raptor%20660&srchType=T"]
def parse(self, response):
hxs = HtmlXPathSelector(response)
titles = hxs.select("//p")
items = []
for titles in titles:
item = CraigslistSampleItem()
item['date'] = titles.select('span[#class="itemdate"]/text()').extract()
item ["title"] = titles.select("a/text()").extract()
item ["link"] = titles.select("a/#href").extract()
item ['price'] = titles.select('//span[#class="itempp"]/text()').extract()
items.append(item)
return items
itempp appears to be inside of another element, itempnr. Perhaps it would work if you were to change //span[#class="itempp"]/text() to span[#class="itempnr"]/span[#class="itempp"]/text().
