Scrapy problems with crawling specific TAG - python

I am having a problem with my scrapy program, I want to crawl information from following website
https://parts.cat.com/AjaxCATPartLookupResultsView?catalogId=10051&langId=-1&requestType=1&storeId=21801&serialNumber=KSN00190&keyword=&link=>
I want to get the "Part No." information inside the "span id=resPartNum" TAG. I have already tried:
- NAME_SELECTOR = './/*[#id="resPartNum"]/text()'
- NAME_SELECTOR = './/span[#class="resPartNum"]/text()
- NAME_SELECTOR = './/tr/td/span[#class="resPartNum"]/a/text()'
Here is my full CODE:
import scrapy
class PartSpider(scrapy.Spider):
name = 'part_spider'
start_urls = ['https://parts.cat.com/AjaxCATPartLookupResultsView?catalogId=10051&langId=-1&requestType=1&storeId=21801&serialNumber=KSN00190&keyword=&link=']
def parse(self, response):
SET_SELECTOR = '.set'
for part in response.css(SET_SELECTOR):
NAME_SELECTOR = './/*[#id="resPartNum"]/text()'
yield {
'name': part.css(NAME_SELECTOR).extract_first(),
}
I am not very advanced in scrapy and would appreciate ANY HELP!!


Use the css selector table.partlookup_table to collect the table item through loop partNum and partName.here extract() return list.
import scrapy
class PartSpider(scrapy.Spider):
name = 'part_spider'
start_urls = ['https://parts.cat.com/AjaxCATPartLookupResultsView?catalogId=10051&langId=-1&requestType=1&storeId=21801&serialNumber=KSN00190&keyword=&link=']
def parse(self, response):
SET_SELECTOR = 'table.partlookup_table'
for part in response.css(SET_SELECTOR):
#NAME_SELECTOR = './/*[#id="resPartNum"]/text()'
yield {
'name': part.css('span.resPartName a::text').extract(),
'partnumber': part.css('span.resPartNum a::text').extract()
}
process = CrawlerProcess()
process.crawl(PartSpider)
process.start()

Scraping Tripadvisor attractions using scrapy and python

I am trying to scrape TripAdvisor's attractions, but I cannot get the names and addresses of each attraction. I suspect I wrote product.css(...) wrong (there are jsons?).
Can anyone tell me how to correct the code to get the name and address of each attraction?
My current code:
import scrapy
class QuotesSpider(scrapy.Spider):
name = "quotes"
start_urls = [
'https://www.tripadvisor.com/Attractions-g187427-Activities-oa90-Spain'
]
def parse(self, response):
for link in response.css('.EsZYd a::attr(href)'):
yield response.follow(link.get(), callback=self.parse_categories)
def parse_categories(self, response):
products = response.css('div.eeqnt')
for product in products:
yield {
'name' : product.css('h1.WlYyy cPsXC GeSzT::text').get().strip(),
'address' : product.css('span.WlYyy cacGK Wb::text').get().strip(),
}
Updated code (exporting infro from each atrraction on each page from list):
import scrapy
class QuotesSpider(scrapy.Spider):
name = "quotes"
start_urls = [

It's not really related to python, but css-selectors.
CSS classes should separate with dot and not space WlYyy.cPsXC.GeSzT.
Best suggestion would be to use chrome with dev-toolbar. It will give you an ability to get path to the specific element via css-selector or xpath, just right-click on the element in a DOM-tree and select copy menu-item.
Avoid using classes (especially one without semantic meaning) as an anchor point. They might change from page to page, or in time.
Better to use semantically meaningful nodes, like in your case:
XPath for the title would looks like this //main//header//div[#data-automation="main_h1"]//h1.

You can't use for loop in each listing page

scraping e-commerce website using scrapy concept

I'm new to this scrapy concept. I have written a script for E-commerce website and need to scrape below mentioned details in that website. I facing issue with this script. please anyone help me to get out from this issue.
website:https://savedbythedress.com/collections/maternity-tops
import scrapy
class DressSpider(scrapy.Spider):
name = 'dress'
allowed_domains = ['savedbythedress.com']
start_urls = ['https://savedbythedress.com/collections/maternity-tops']
def parse(self, response):
#scraped all product links
domain = "https://savedbythedress.com"
link_products = response.css('div[class="product-info-inner"] ::attr(href)').get()
for link in link_products:
product_link = domain + link
yield{
'product_link': product_link.css('div[class="product-info-inner"] ::attr(href)').get(),
}
yield scrapy.Request(url=product_link, callback=self.parse_contents)

use yield response.follow(page_url, self.parse_contents) it will work for you
import scrapy

How can I Scrape next pages with Scrapy

Here is my scrapy code.I dont know my mistake but in only scrapes first page.How can i scrape and traverse through pages ? Is there any other way for scraping next pages ?
import scrapy
class HurriyetEmlakPage(scrapy.Spider):
name = 'hurriyetspider'
allowed_domain = 'hurriyetemlak.com'
start_urls = ['https://www.hurriyetemlak.com/satilik']
def parse(self, response):
fiyat = response.xpath('//div[#class="list-view-price"]//text()').extract()
durum = response.xpath('//div[#class="middle sibling"]//div[#class="left"]//text()').extract()
oda_sayisi = response.xpath('//span[#class="celly houseRoomCount"]//text()').extract()
metrekare = response.xpath('//span[#class="celly squareMeter list-view-size"]//text()').extract()
bina_yasi = response.xpath('//span[#class="celly buildingAge"]//text()').extract()
bulundugu_kat = response.xpath('//span[#class="celly floortype"]//text()').extract()
konum = response.xpath('//div[#class="list-view-location"]//text()').extract()
scraped_info = {
'fiyat':fiyat,
'durum': durum,
'oda_sayisi' : oda_sayisi,
'metrekare' : metrekare,
'bina_yasi' : bina_yasi,
'bulundugu_kat': bulundugu_kat,
'konum' : konum
}
yield scraped_info
next_page_url = response.xpath('//li[#class="next-li pagi-nav"]//a').extract_first()
if next_page_url:
next_page_url = response.urljoin(next_page_url)
yield scrapy.Request(url = next_page_url,callback = self.parse)

Actually, you could simply generate your url list like this :
url_list = [f"https://www.hurriyetemlak.com/satilik?page={page}" for page in range(1,7326)]
Output
['https://www.hurriyetemlak.com/satilik?page=1',
'https://www.hurriyetemlak.com/satilik?page=2',
'https://www.hurriyetemlak.com/satilik?page=3',
'https://www.hurriyetemlak.com/satilik?page=4',
'https://www.hurriyetemlak.com/satilik?page=5',

Why Is the Web Crawler I made with Python not working?

I am following a tutorial on webscraping by Justin Duke of Digital Ocean. Here is the link to the tutorial
https://www.digitalocean.com/community/tutorials/how-to-crawl-a-web-page-with-scrapy-and-python-3
When I run my code, the web crawler displays the following error:
'BrickSetSpider.parse callback is 'not defined'.
I'm not sure what this means.
Here is the code I used.
import scrapy
class BrickSetSpider(scrapy.Spider):
name = "brickset_spider"
start_urls = ['http://brickset.com/sets/year-2016']
def parse(self, response):
SET_SELECTOR = '.set'
for brickset in response.css(SET_SELECTOR):
NAME_SELECTOR = 'h1 ::text'
yield {
'name': brickset.css(NAME_SELECTOR).extract_first(),
}
I am also pretty new to Python. So, I would appreciate it if your answer to my question was written in such a way that a noobie would be able to understand it.

Like this
import scrapy
class BrickSetSpider(scrapy.Spider):
name = "brickset_spider"
start_urls = ['http://brickset.com/sets/year-2016']
def parse(self, response):
SET_SELECTOR = '.set'
for brickset in response.css(SET_SELECTOR):
NAME_SELECTOR = 'h1 ::text'
yield {
'name': brickset.css(NAME_SELECTOR).extract_first(),
}

Use scrapy to get list of urls, and then scrape content inside those urls

I need a Scrapy spider to scrape the following page (https://www.phidgets.com/?tier=1&catid=64&pcid=57) for each URL (30 products, so 30 urls) and then go into each product via that url and scrape the data inside.
I have the second part working exactly as I want:
import scrapy
class ProductsSpider(scrapy.Spider):
name = "products"
start_urls = [
'https://www.phidgets.com/?tier=1&catid=64&pcid=57',
]
def parse(self, response):
for info in response.css('div.ph-product-container'):
yield {
'product_name': info.css('h2.ph-product-name::text').extract_first(),
'product_image': info.css('div.ph-product-img-ctn a').xpath('#href').extract(),
'sku': info.css('span.ph-pid').xpath('#prod-sku').extract_first(),
'short_description': info.css('div.ph-product-summary::text').extract_first(),
'price': info.css('h2.ph-product-price > span.price::text').extract_first(),
'long_description': info.css('div#product_tab_1').extract_first(),
'specs': info.css('div#product_tab_2').extract_first(),
}
# next_page = response.css('div.ph-summary-entry-ctn a::attr("href")').extract_first()
# if next_page is not None:
# yield response.follow(next_page, self.parse)
But I don't know how to do the first part. As you will see I have the main page (https://www.phidgets.com/?tier=1&catid=64&pcid=57) set as the start_url. But how do I get it to populate the start_urls list with all 30 urls I need crawled?

I am not able to test at this moment, so please let me know if this works for you so I can edit it should there be any bugs.
The idea here is that we find every link in the first page and yield new scrapy requests passing your product parsing method as a callback
import scrapy
from urllib.parse import urljoin
class ProductsSpider(scrapy.Spider):
name = "products"
start_urls = [
'https://www.phidgets.com/?tier=1&catid=64&pcid=57',
]
def parse(self, response):
products = response.xpath("//*[contains(#class, 'ph-summary-entry-ctn')]/a/#href").extract()
for p in products:
url = urljoin(response.url, p)
yield scrapy.Request(url, callback=self.parse_product)
def parse_product(self, response):
for info in response.css('div.ph-product-container'):
yield {
'product_name': info.css('h2.ph-product-name::text').extract_first(),
'product_image': info.css('div.ph-product-img-ctn a').xpath('#href').extract(),
'sku': info.css('span.ph-pid').xpath('#prod-sku').extract_first(),
'short_description': info.css('div.ph-product-summary::text').extract_first(),
'price': info.css('h2.ph-product-price > span.price::text').extract_first(),
'long_description': info.css('div#product_tab_1').extract_first(),
'specs': info.css('div#product_tab_2').extract_first(),
}
