Unable to parse html in Python - python

Why am i not able to parse this web page which is in html into a csv?
url='c:/x/x/x/xyz.html' #html(home page of www.cloudtango.org) data is stored inside a local drive
with open(url, 'r',encoding='utf-8') as f:
html_string = f.read()
soup= bs4.BeautifulSoup('html_string.parser')
data1= html_string.find_all('td',{'class':'company'})
full=[]
for each in data1:
comp= each.find('img')['alt']
desc= each.find_next('td').text
dd={'company':comp,'description':desc}
full.append(dd)
Error:
AttributeError: 'str' object has no attribute 'find_all'

The html_string is of type string, it doesn't have .find_all() method.
To get information from specified URL, you can use next example:
import requests
import pandas as pd
from bs4 import BeautifulSoup
url = "https://www.cloudtango.org/"
headers = {
"User-Agent": "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:89.0) Gecko/20100101 Firefox/89.0"
}
soup = BeautifulSoup(requests.get(url, headers=headers).content, "html.parser")
data1 = soup.find_all("td", {"class": "company"})
full = []
for each in data1:
comp = each.find("img")["alt"]
desc = each.find_next("td").text
dd = {"company": comp, "description": desc}
full.append(dd)
print(pd.DataFrame(full))
Prints:

how can I scrape data beyond the page limit on Zillow?

I created a code to scrape the Zillow data and it works fine. The only problem I have is that it's limited to 20 pages even though there are many more results. Is there a way to get around this page limitation and scrap all the data ?
I also wanted to know if there is a general solution to this problem since I encounter it practically in every site that I want to scrape.
Thank you

Actually, you can't grab any data from zillow using bs4 because they are dynamically loaded by JS and bs4 can't render JS. Only 6 to 8 data items are static. All data are lying down in script tag with html comment as json format. How to pull the requied data? In this case you can follow the next example.
Thus way you can extract all the items. So to pull rest of data items, is your task or just add your data items here.
Zillow is one of the most famous and smart enough websites. So we should respect its terms and conditions.
Example:
import requests
import re
import json
import pandas as pd
url='https://www.zillow.com/fl/{page}_p/?searchQueryState=%7B%22usersSearchTerm%22%3A%22FL%22%2C%22mapBounds%22%3A%7B%22west%22%3A-94.21964006249998%2C%22east%22%3A-80.68448381249998%2C%22south%22%3A22.702203494269085%2C%22north%22%3A32.23788425255877%7D%2C%22regionSelection%22%3A%5B%7B%22regionId%22%3A14%2C%22regionType%22%3A2%7D%5D%2C%22isMapVisible%22%3Afalse%2C%22filterState%22%3A%7B%22sort%22%3A%7B%22value%22%3A%22days%22%7D%2C%22ah%22%3A%7B%22value%22%3Atrue%7D%7D%2C%22isListVisible%22%3Atrue%2C%22mapZoom%22%3A6%2C%22pagination%22%3A%7B%22currentPage%22%3A2%7D%7D'
lst=[]
for page in range(1,21):
r = requests.get(url.format(page=page),headers = {'User-Agent':'Mozilla/5.0'})
data = json.loads(re.search(r'!--(\{"queryState".*?)-->', r.text).group(1))
for item in data['cat1']['searchResults']['listResults']:
price= item['price']
lst.append({'price': price})
df = pd.DataFrame(lst).to_csv('out.csv',index=False)
print(df)
Output:

Extracting the required information for a Script tag of scraped webpage using BeautifulSoup

I'm a webscraping novice and I am looking for pointers of what to do next, or potentially a working solution, to scrape the following webpage: https://www.capology.com/club/leicester/salaries/2019-2020/
I would like to extract the following for each row (player) of the table:
Player Name i.e. Jamie Vardy
Weekly Gross Base Salary (in GBP) i.e. £140,000
Annual Gross Base Salary (in GBP) i.e. £7,280,000
Position i.e. F
Age i.e. 33
Country England
The following code creates the 'soup' for the JavaScript table of information I want:
import requests
from bs4 import BeautifulSoup
import json
headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:75.0) Gecko/20100101 Firefox/75.0'}
url = 'https://www.capology.com/club/leicester/salaries/2019-2020/'
r = requests.get(url)
soup = BeautifulSoup(r.content, 'html.parser')
script = soup.find_all('script')[11].string # 11th script tag in the webpage
I can see the 'soup' assigned to the script variable has all the information I need, however, I am struggling to extract the information that I need as a pandas DataFrame?
I would subsequently like to set up this up for pagination, to scrape each team in the the 'Big 5' European Leagues (Premier League, Serie A, La Liga, Bundeliga, and Ligue 1), for the 17-18, 18-19, 19-20, and 20-21 (current) seasons. However, that's the final stage solution and I am happy to go away and try and do that myself if that's a time consuming request.
A working solution would be fantastic but just some pointers so that I can go away and learn this stuff myself as efficiently as possible would be great.
Thanks very much!
This is a task that is best suited for a tool like selenium, as the site uses the scrip to populate the page with the table after it loads, and it is not trivial to parse the values from the script source:
from selenium import webdriver
from bs4 import BeautifulSoup as soup
import urllib.parse, collections, re
d = webdriver.Chrome('/path/to/chromedriver')
d.get((url:='https://www.capology.com/club/leicester/salaries/2019-2020/'))
league_teams = d.execute_script("""
var results = [];
for (var i of Array.from(document.querySelectorAll('li.green-subheader + li')).slice(0, 5)){
results.push({league:i.querySelector('.league-title').textContent,
teams:Array.from(i.querySelectorAll('select:nth-of-type(1).team-menu option')).map(x => [x.getAttribute('value'), x.textContent]).slice(1),
years:Array.from(i.querySelectorAll('select:nth-of-type(2).team-menu option')).map(x => [x.getAttribute('value'), x.textContent]).slice(2)})
}
return results;
""")
vals = collections.defaultdict(dict)
for i in league_teams:
for y, full_year in [[re.sub('\d{4}\-\d{4}', '2020-2021', i['years'][0][0]), '2020-21'], *i['years']][:4]:
for t, team in i['teams']:
d.get(urllib.parse.urljoin(url, t) + (y1:=re.findall('/\d{4}\-\d{4}/', y)[0][1:]))
hvals = [x.get_text(strip=True) for x in soup(d.page_source, 'html.parser').select('#table thead tr:nth-of-type(3) th')]
tvals = soup(d.page_source, 'html.parser').select('#table tbody tr')
full_table = [dict(zip(hvals, [j.get_text(strip=True) for j in k.select('td')])) for k in tvals]
if team not in vals[i['league']]:
vals[i['league']][team] = {full_year:None}
vals[i['league']][team][full_year] = full_table

Web-scrape. BeautifulSoup. Multiple Pages. How on earth would you do that?

Hi I am a Newbie to programming. So I spent 4 days trying to learn python. I evented some new swear words too.
I was particularly interested in trying as an exercise some web-scraping to learn something new and get some exposure to see how it all works.
This is what I came up with. See code at end. It works (to a degree)
But what's missing?
This website has pagination on it. In this case 11 pages worth.  How would you go about adding to this script and getting python to go look at those other pages too and carry out the same scrape. Ie scrape page one , scrape page 2, 3 ... 11 and post the results to a csv?
https://www.organicwine.com.au/vegan/?pgnum=1
https://www.organicwine.com.au/vegan/?pgnum=2
https://www.organicwine.com.au/vegan/?pgnum=3
https://www.organicwine.com.au/vegan/?pgnum=4
https://www.organicwine.com.au/vegan/?pgnum=5
https://www.organicwine.com.au/vegan/?pgnum=6
https://www.organicwine.com.au/vegan/?pgnum=7
8, 9,10, and 11
On these pages the images are actually a thumbnail images something like 251px by 251px.
How would you go about adding to this script to say. And whilst you are at it follow the links to the detailed product page and capture the image link from there where the images are 1600px by 1600px and post those links to CSV
https://www.organicwine.com.au/mercer-wines-preservative-free-shiraz-2020
When we have identified those links lets also download those larger images to a folder
CSV writer. Also I don't understand line 58
for i in range(23)
how would i know how many products there were without counting them (i.e. there is 24 products on page one)
So this is what I want to learn how to do. Not asking for much (he says sarcastically) I could pay someone on up-work to do it but where's the fun in that? and that does not teach me how to 'fish'.
Where is a good place to learn python? A master class on web-scraping. It seems to be trial and error and blog posts and where ever you can pick up bits of information to piece it all together.
Maybe I need a mentor.
I wish there had been someone I could have reached out to, to tell me what beautifulSoup was all about. worked it out by trial and error and mostly guessing. No understanding of it but it just works.
Anyway, any help in pulling this all together to produce a decent script would be greatly appreciated.
Hopefully there is someone out there who would not mind helping me.
Apologies to organicwine for using their website as a learning tool. I do not wish to cause any harm or be a nuisance to the site
Thank you in advance
John

# """ writing data to CSV """
# open OrganicWine2.csv file in "write" mode
# newline stops a blank line appearing in csv
with open('OrganicWine2.csv', 'w',newline='') as file:
# create a "writer" object
writer = csv.writer(file, delimiter=',')
# use "writer" obj to write
# you should give a "list"
writer.writerow(["Wine Name", "Wine Price", "Wine Image Link"])
for i in range(23):
writer.writerow([
winename[i],
price[i],
image[i],
])
In this case, to do pagination, instead of for i in range(1, 100) which is a hardcoded way of paging, it's better to use a while loop to dynamically paginate all possible pages.
"While" is an infinite loop and it will be executed until the transition to the next page is possible, in this case it will check for the presence of the button for the next page, for which the CSS selector ".fa-chevron-right" is responsible:
if soup.select_one(".fa-chevron-right"):
params["pgnum"] += 1 # go to the next page
else:
break
To extract the full size image an additional request is required, CSS selector ".main-image a" is responsible for full-size images:
full_image_html = requests.get(link, headers=headers, timeout=30)
image_soup = BeautifulSoup(full_image_html.text, "lxml")
try:
original_image = f'https://www.organicwine.com.au{image_soup.select_one(".main-image a")["href"]}'
except:
original_image = None
An additional step to avoid being blocked is to rotate user-agents. Ideally, it would be better to use residential proxies with random user-agent.
pandas can be used to extract data in CSV format:
pd.DataFrame(data=data).to_csv("<csv_file_name>.csv", index=False)
For a quick and easy search for CSS selectors, you can use the SelectorGadget Chrome extension (not always work perfectly if the website is rendered via JavaScript).
Check code with pagination and saving information to CSV in online IDE.

Create the URL by putting the page number in it, then put the rest of your code into a for loop and you can use len(winenames) to count how many results you have. You should do the writing outside the for loop. Here's your code with those changes:
import requests
import csv
from bs4 import BeautifulSoup
num_pages = 11
result = []
for pgnum in range(num_pages):
url = f"https://www.organicwine.com.au/vegan/?pgnum={pgnum+1}"
response = requests.get(url)
website_html = response.text
soup = BeautifulSoup(website_html, "html.parser")
product_title = soup.find_all("div", class_="caption")
winename = []
for wine in product_title:
winetext = wine.a.text
winename.append(winetext)
product_price = soup.find_all("div", class_="wrap-thumb-mob")
price = []
for wine in product_price:
wineprice = wine.span.text
price.append(wineprice)
image = []
product_image_link = soup.find_all("div", class_="thumbnail-image")
for imagelink in product_image_link:
winelink = imagelink.a["href"]
response = requests.get(winelink)
wine_page_soup = BeautifulSoup(response.text, "html.parser")
main_image = wine_page_soup.find("a", class_="fancybox")
image.append(main_image['href'])
for i in range(len(winename)):
result.append([winename[i], price[i], image[i]])
with open("/tmp/OrganicWine2.csv", "w", newline="") as file:
writer = csv.writer(file, delimiter=",")
writer.writerow(["Wine Name", "Wine Price", "Wine Image Link"])
writer.writerows(results)
And here's how I would rewrite your code to accomplish this task. It's more pythonic (you should basically never write range(len(something)), there's always a cleaner way) and it doesn't require knowing how many pages of results there are:
import csv
import itertools
import time
import requests
from bs4 import BeautifulSoup
data = []
# Try opening 100 pages at most, in case the scraping code is broken
# which can happen because websites change.
for pgnum in range(1, 100):
url = f"https://www.organicwine.com.au/vegan/?pgnum={pgnum}"
response = requests.get(url)
website_html = response.text
soup = BeautifulSoup(website_html, "html.parser")
search_results = soup.find_all("div", class_="thumbnail")
for search_result in search_results:
name = search_result.find("div", class_="caption").a.text
price = search_result.find("p", class_="price").span.text
# link to the product's page
link = search_result.find("div", class_="thumbnail-image").a["href"]
# get the full resolution product image
response = requests.get(link)
time.sleep(1) # rate limit
wine_page_soup = BeautifulSoup(response.text, "html.parser")
main_image = wine_page_soup.find("a", class_="fancybox")
image_url = main_image["href"]
# or you can just "guess" it from the thumbnail's URL
# thumbnail = search_result.find("div", class_="thumbnail-image").a.img['src']
# image_url = thumbnail.replace('/thumbL/', '/full/')
data.append([name, price, link, image_url])
# if there's no "next page" button or no search results on the current page,
# stop scraping
if not soup.find("i", class_="fa-chevron-right") or not search_results:
break
# rate limit
time.sleep(1)
with open("/tmp/OrganicWine3.csv", "w", newline="") as file:
writer = csv.writer(file, delimiter=",")
writer.writerow(["Wine Name", "Wine Price", "Wine Link", "Wine Image Link"])
writer.writerows(data)

Scraping a website with a particular format using Python

I am trying to use Python to scrape the US News Ranking for universities, and I'm struggling. I normally use Python "requests" and "BeautifulSoup".
The data is here:
https://www.usnews.com/education/best-global-universities/rankings
Using right click and inspect shows a bunch of links and I don't even know which one to pick. I followed an example from the web that I found but it just gives me empty data:
import requests
import urllib.request
import time
from bs4 import BeautifulSoup
import pandas as pd
import math
from lxml.html import parse
from io import StringIO
url = 'https://www.usnews.com/education/best-global-universities/rankings'
urltmplt = 'https://www.usnews.com/education/best-global-universities/rankings?page=2'
css = '#resultsMain :nth-child(1)'
npage = 20
urlst = [url] + [urltmplt + str(r) for r in range(2,npage+1)]
def scrapevec(url, css):
doc = parse(StringIO(url)).getroot()
return([link.text_content() for link in doc.cssselect(css)])
usng = []
for u in urlst:
print(u)
ts = [re.sub("\n *"," ", t) for t in scrapevec(u,css) if t != ""]
This doesn't work as t is an empty array.
I'd really appreciate any help.
The MWE you posted is not working at all: urlst is never defined and cannot be called. I strongly suggest you to look for basic scraping tutorials (with python, java, etc.): there is plenty and in general is a good starting.
Below you can find a snippet of a code that prints the universities' names listed on page 1 - you'll be able to extend the code to all the 150 pages through a for loop.
import requests
from bs4 import BeautifulSoup
newheaders = {
'User-Agent': 'Mozilla/5.0 (X11; Linux i686 on x86_64)'
}
baseurl = 'https://www.usnews.com/education/best-global-universities/rankings'
page1 = requests.get(baseurl, headers = newheaders) # change headers or get blocked
soup = BeautifulSoup(page1.text, 'lxml')
res_tab = soup.find('div', {'id' : 'resultsMain'}) # find the results' table
for a,univ in enumerate(res_tab.findAll('a', href = True)): # parse universities' names
if a < 10: # there are 10 listed universities per page
print(univ.text)
Edit: now the example works, but as you say in your question, it only returns empty lists. Below an edited version of the code that returns a list of all universities (pp. 1-150)
import requests
from bs4 import BeautifulSoup
def parse_univ(url):
newheaders = {
'User-Agent': 'Mozilla/5.0 (X11; Linux i686 on x86_64)'
}
page1 = requests.get(url, headers = newheaders) # change headers or get blocked
soup = BeautifulSoup(page1.text, 'lxml')
res_tab = soup.find('div', {'id' : 'resultsMain'}) # find the results' table
res = []

Re-edit following QHarr suggestion (thanks!) - same output, shorter and more "pythonic" solution

Not able to scrape the all the reviews

I am trying to scrape this website and trying to get the reviews but I am facing an issue,
The page loads only 50 reviews.
To load more you have to click "Show More Reviews" and I don't know how to get all the data as there is no page link, also "Show more Reviews" doesn't have a URL to explore, the address remains the same.
url =
"https://www.capterra.com/p/134048/HiMama-Preschool-Child-Care-App/#reviews"
import requests
from bs4 import BeautifulSoup
import json
import pandas as pd
a = []
url = requests.get(url)
html = url.text
soup = BeautifulSoup(html, "html.parser")
table = soup.findAll("div", {"class":"review-comments"})
#print(table)
for x in table:
a.append(x.text)
df = pd.DataFrame(a)
df.to_csv("review.csv", sep='\t')
I know this is not pretty code but I am just trying to get the review text first.
kindly help. As I am little new to this.
Looking at the website, the "Show more reviews" button makes an ajax call and returns the additional info, all you have to do is find it's link and send a get request to it (which I've done with some simple regex):
import requests
import re
from bs4 import BeautifulSoup
headers = {
"user-agent": "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) snap Chromium/74.0.3729.169 Chrome/74.0.3729.169 Safari/537.36"
}
url = "https://www.capterra.com/p/134048/HiMama-Preschool-Child-Care-App/#reviews"
Data = []
#Each page equivalant to 50 comments:
MaximumCommentPages = 3
with requests.Session() as session:
info = session.get(url)
#Get product ID, needed for getting more comments
productID = re.search(r'"product_id":(\w*)', info.text).group(1)
#Extract info from main data
soup = BeautifulSoup(info.content, "html.parser")
table = soup.findAll("div", {"class":"review-comments"})
for x in table:
Data.append(x)
#Number of pages to get:
#Get additional data:
params = {
"page": "",
"product_id": productID
}
while(MaximumCommentPages > 1): # number 1 because one of them was the main page data which we already extracted!
MaximumCommentPages -= 1
params["page"] = str(MaximumCommentPages)
additionalInfo = session.get("https://www.capterra.com/gdm_reviews", params=params)
print(additionalInfo.url)
#print(additionalInfo.text)
#Extract info for additional info:
soup = BeautifulSoup(additionalInfo.content, "html.parser")
table = soup.findAll("div", {"class":"review-comments"})
for x in table:
Data.append(x)
#Extract data the old fashioned way:
counter = 1
with open('review.csv', 'w') as f:
for one in Data:
f.write(str(counter))
f.write(one.text)
f.write('\n')
counter += 1
Notice how I'm using a session to preserve cookies for the ajax call.
Edit 1: You can reload the webpage multiple times and call the ajax again to get even more data.
Edit 2: Save data using your own method.
Edit 3: Changed some stuff, now gets any number of pages for you, saves to file with good' ol open()
