DB and BeautifulSoup - python

I would like to get from a search request to the site of the DB the sourcecode of the website and read out later values. However, I'm using BeautifulSoup and get a different sourcecode than in the browser! Have anyone an idea why this happens?
import bs4
import urllib.request
page = urllib.request.urlopen("http://reiseauskunft.bahn.de/bin/query.exe/dox?S=8000096&Z=8079090&start=1")
soup = bs4.BeautifulSoup(page, "html.parser")
print(soup)

How do I log data from a live website using beautiful soup

Hello I am trying to use beautiful soup and requests to log the data coming from an anemometer which updates live every second. The link to this website here:
http://88.97.23.70:81/
The piece of data I want to scrape is highlighted in purple in the image :
from inspection of the html in my browser.
I have written the code bellow in to try to print out the data however when I run the code it prints: None. I think this means that the soup object doesnt infact contain the whole html page? Upon printing soup.prettify() I cannot find the same id=js-2-text I find when inspecting the html in my browser. If anyone has any ideas why this might be or how to fix it I would be most grateful.
from bs4 import BeautifulSoup
import requests
wind_url='http://88.97.23.70:81/'
r = requests.get(wind_url)
data = r.text
soup = BeautifulSoup(data, 'lxml')
print(soup.find(id='js-2-text'))
All the best,
Brendan
The data is loaded from external URL, so beautifulsoup doesn't need it. You can try to use API URL the page is connecting to:
import requests
from bs4 import BeautifulSoup
api_url = "http://88.97.23.70:81/cgi-bin/CGI_GetMeasurement.cgi"
data = {"input_id": "1"}
soup = BeautifulSoup(requests.post(api_url, data=data).content, "html.parser")
_, direction, metres_per_second, *_ = soup.csv.text.split(",")
knots = float(metres_per_second) * 1.9438445
print(direction, metres_per_second, knots)
Prints:
210 006.58 12.79049681

unable to Webscrape dropdown item [Python][beautifulsoup]

i am new to webscraping, i am scraping a website - https://www.valueresearchonline.com/funds/22/uti-mastershare-fund-regular-plan/
In this,i want to scrape this text - Regular Plan
But the thing is, when i do it using inspect element,
code -
import requests
from bs4 import BeautifulSoup
import csv
import sys
url = 'https://www.valueresearchonline.com/funds/newsnapshot.asp?schemecode=22'
res = requests.get(url)
soup = BeautifulSoup(res.text, "html.parser")
regular_direct = soup.find('span',class_="filter-option pull-left").text
print(regular_direct)
i get none in printing, and i don't know why, the code in inspect element and view page source is also different, because in view page source, this span and class is not there.
why i am getting none?? can anyone please tell me and how can i get that text and why inspect element code and view page source code are different?
You need to change the selector because the html source that gets downloaded is different.
import requests
from bs4 import BeautifulSoup
import csv
import sys
url = 'https://www.valueresearchonline.com/funds/newsnapshot.asp?schemecode=22'
res = requests.get(url)
soup = BeautifulSoup(res.text, "html.parser")
regular_direct = soup.find("select", {"id":"select-plan"}).find("option",{"selected":"selected"}).get_text(strip=True)
print(regular_direct)
Output:
Regular plan

How to scrape a specific table form website using python (beautifulsoup4 and requests or any other library)?

https://en.wikipedia.org/wiki/Economy_of_the_European_Union
Above is the link to website and I want to scrape table: Fortune top 10 E.U. corporations by revenue (2016).
Please, share the code for the same:
import requests
from bs4 import BeautifulSoup
def web_crawler(url):
page = requests.get(url)
plain_text = page.text
soup = BeautifulSoup(plain_text,"html.parser")
tables = soup.findAll("tbody")[1]
print(tables)
soup = web_crawler("https://en.wikipedia.org/wiki/Economy_of_the_European_Union")
following what #FanMan said , this is simple code to help you get started, keep in mind that you will need to clean it and also perform the rest of the work on your own.
import requests
from bs4 import BeautifulSoup
url='https://en.wikipedia.org/wiki/Economy_of_the_European_Union'
r=requests.get(url)
soup = BeautifulSoup(r.text, 'html.parser')
temp_datastore=list()
for text in soup.findAll('p'):
w=text.findAll(text=True)
if(len(w)>0):
temp_datastore.append(w)
Some documentation
beautiful soup:https://www.crummy.com/software/BeautifulSoup/bs4/doc/
requests: http://docs.python-requests.org/en/master/user/intro/
urllib: https://docs.python.org/2/library/urllib.html
You're first issue is that your url is not properly defined. After that you need to find the table to extract and it's class. In this case the class was "wikitable" and it was a the first table. I have started your code for you so it gives you the extracted data from the table. Web-scraping is good to learn but if your are just starting to program, practice with some simpler stuff first.
import requests
from bs4 import BeautifulSoup
def webcrawler():
url = "https://en.wikipedia.org/wiki/Economy_of_the_European_Union"
page = requests.get(url)
soup = BeautifulSoup(page.text,"html.parser")
tables = soup.findAll("table", class_='wikitable')[0]
print(tables)
webcrawler()

Having trouble in getting page source with beautifulsoup

I am trying to get the HTML source of a web page using beautifulsoup.
import bs4 as bs
import requests
import urllib.request
sourceUrl='https://www.pakwheels.com/forums/t/planing-a-trip-from-karachi-to-lahore-by-road-in-feb-2017/414115/2.html'
source=urllib.request.urlopen(sourceUrl).read()
soup=bs.BeautifulSoup(source,'html.parser')
print(soup)
I want the HTML source of the page. This is what I am getting now:
'ps.store("siteSettings", {"title":"PakWheels Forums","contact_email":"sami.ullah#pakeventures.com","contact_url":"https://www.pakwheels.com/main/contact_us","logo_url":"https://www.pakwheels.com/assets/logo.png","logo_small_url":"/images/d-logo-sketch-small.png","mobile_logo_url":"data:image/svg+xml;base64,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'
Have a look at this code:
from urllib import request
from bs4 import BeautifulSoup
url_1 = "http://www.google.com"
page = request.urlopen(url_1)
soup = BeautifulSoup(page)
print(soup.prettify())
Import everything you need correctly. Read this.

BeautifulSoup does not work for some web sites

I have this sript:
import urrlib2
from bs4 import BeautifulSoup
url = "http://www.shoptop.ru/"
page = urllib2.urlopen(url).read()
soup = BeautifulSoup(page)
divs = soup.findAll('a')
print divs
For this web site, it prints empty list? What can be problem? I am running on Ubuntu 12.04
Actually there are quite couple of bugs in BeautifulSoup which might raise some unknown errors. I had a similar issue when working on apache using lxml parser
So, just try to use other couple of parsers mentioned in the documentation
soup = BeautifulSoup(page, "html.parser")
This should work!
It looks like you have a few mistakes in your code urrlib2 should be urllib2, I've fixed the code for you and this works using BeautifulSoup 3
import urllib2
from BeautifulSoup import BeautifulSoup
url = "http://www.shoptop.ru/"
page = urllib2.urlopen(url).read()
soup = BeautifulSoup(page)
divs = soup.findAll('a')
print divs
