how to crawl vue.js based website with beautifulsoup? - python

I've tried to crawl a website using beautifulsoup and I've encountered with:
<p data-v-57d17052 class="text text--gray70 text--subtitle2">Hello</p>
and this, for some reason, doesn't allow me to use beatifulsoup's features.
title = soup.find_all(class_={"text, text--gray70, text--subtitle2"})
I think data-v-57d17052 is causing this difficulty.
Does anyone know how to solve this issue?
I have tried all beautifulsoup's features and it doesn't work at all.

Remove the comma from the class_=:
from bs4 import BeautifulSoup
html_doc = ''''<p data-v-57d17052 class="text text--gray70 text--subtitle2">Hello</p>'''
soup = BeautifulSoup(html_doc, 'html.parser')
title = soup.find(class_={"text text--gray70 text--subtitle2"})
print(title.text)
Prints:
Hello
You can use also a CSS selector:
title = soup.select_one(".text.text--gray70.text--subtitle2")
print(title.text)

beautiful soup find text of path that contains div and span

I am a beginner in Python3, I am working on selenium project for a website
the text that i want is under the path ("//div[#class='classname']//span[#class='classname2']).text
but i cannot extract it without a beautifulsoup
for i in postsContainer.extract():
soup = bs(i)
people.append([soup.find("div",{"class":"classname"}).text])
but It doesn't work without the //span part. How can I insert my path in a beautifulsoup?
If someone can help
If there would be some more html to inspect, we would maybe find a better solution, but you can use the css selectors in this case
soup.select_one('div.css-901oao.r-18jsvk2.r-1qd0xha.r-a023e6.r-16dba41.r-ad9z0x.r-bcqeeo.r-bnwqim.r-qvutc0 > span.css-901oao.css-16my406.r-poiln3.r-bcqeeo r-qvutc0').get_text()
or:
soup.select_one('div.css-901oao.r-18jsvk2.r-1qd0xha.r-a023e6.r-16dba41.r-ad9z0x.r-bcqeeo.r-bnwqim.r-qvutc0 > span').get_text()
Example
from bs4 import BeautifulSoup
html='''
<div class="classname">
<span class="classname2">text</span>
</div>
'''
soup = BeautifulSoup(html,'html.parser')
soup.select_one('div.classname span.classname2').get_text()

Python BeautifulSoup trouble extracting titles from a page with JS

I'm having some serious issues trying to extract the titles from a webpage. I've done this before on some other sites but this one seems to be an issue because of the Javascript.
The test link is "https://www.thomasnet.com/products/adhesives-393009-1.html"
The first title I want extracted is "Toagosei America, Inc."
Here is my code:
import requests
from bs4 import BeautifulSoup
url = ("https://www.thomasnet.com/products/adhesives-393009-1.html")
r = requests.get(url).content
soup = BeautifulSoup(r, "html.parser")
print(soup.get_text())
Now if I run it like this, with get_text, i can find the titles in the result, however as soon as I change it to find_all or find, the titles are lost. I cant find them using web browser's inspect tool, because its all JS generated.
Any advice would be greatly appreciated.
You have to specify what to find, in this case <h2> to get first title:
import requests
from bs4 import BeautifulSoup
url = 'https://www.thomasnet.com/products/adhesives-393009-1.html'
soup = BeautifulSoup(requests.get(url).content, 'html.parser')
first_title = soup.find('h2')
print(first_title.text)
Prints:
Toagosei America, Inc.

problems scraping web page using python

Hi I'm quite new to python and my boss has asked me to scrape this data however it is not my strong point so i was wondering how i would go about this.
The text that I'm after also changes in the quote marks every few minutes so I'm also not sure how to locate that.
I am using beautiful soup at the moment and Lxml however if there are better alternatives I'm happy to try them
This is the inspected element of the webpage:
div class = "sometext"
<h3> somemoretext </h3>
<p>
<span class = "title" title="text i want">text i want</span>
<br>
</p>
I have tried using:
from lxml import html
import requests
from bs4 import BeautifulSoup
page = requests.get('the url')
soup = BeautifulSoup(page.text)
r = soup.findAll('//span[#class="title"]/text()')
print r
Thank you in advance,any help would be appreciated!
First do this to get what you are looking at in the soup:
soup = BeautifulSoup(page)
print soup
That way you can double check that you are actually dealing will what you think you are dealing with.
Then do this:
r = soup.findAll('span', attrs={"class":"title"})
for span in r:
print span.text
This will get all the span tags with a class=title, and then text will print out all the text in between the tags.
Edited to Add
Note that esecules' answer will get you the title within the tag (<span class = "title" title="text i want">) whereas mine will get the title from the text (<span class = "title" >text i want</span>)
perhaps find is the method you really need since you're only ever looking for one element. docs
r = soup.find('div', 'sometext').find('span','title')['title']
if you're familiar with XPath and you don't need feature that specific to BeautifulSoup, then using lxml only is enough (or maybe even better since lxml is known to be faster) :
from lxml import html
import requests
page = requests.get('the url')
root = html.fromstring(page.text)
r = root.xpath('//span[#class="title"]/text()')
print r

Beautiful Soup can't get news titles

from bs4 import BeautifulSoup
import requests
url ="http://www.basketnews.lt/lygos/59-nacionaline-krepsinio-asociacija/2013/naujienos.html"
r = requests.get(url)
soup = BeautifulSoup(r.text)
naujienos = soup.findAll('a', {'class':'title'})
print naujienos
Here is important part of HTML:
<div class="title">
<span class="feedbacks"></span>
</div>
I get empty list. Where is my mistake?
EDIT:
Thanks it worked. Now I want to print news titles. This is how I am trying to do it:
nba = soup.select('div.title > a')
for i in nba:
print ""+i.string+"\n"
I get max 5 titles and error occurs: cannot concatenate 'str' and 'NoneType' objects
soup.findAll('a', {'class':'title'})
This says, give me all a tags that also have class="title". That's obviously not what you're trying to do.
I think you want a tags that are the direct descendant of a tag with class="title". You can try using a css selector:
soup.select('div.title > a')

Improving a python snippet

I'm working on a python script to do some web scraping. I want to find the base URL of a given section on a web page that looks like this:
<div class='pagination'>
<a href='webpage-category/page/1'>1</a>
<a href='webpage-category/page/2'>2</a>
...
</div>
So, I just need to get everything from the first href besides the number('webpage-category/page/') and I have the following working code:
pages = [l['href'] for link in soup.find_all('div', class_='pagination')
for l in link.find_all('a') if not re.search('pageSub', l['href'])]
s = pages[0]
f = ''.join([i for i in s if not i.isdigit()])
The problem is, generating this list is a waste, since I just need the first href. I think a Generator would be the answer but I couldn't pull this off. Maybe you guys could help me to make this code more concise?
What about this:
from bs4 import BeautifulSoup
html = """ <div class='pagination'>
<a href='webpage-category/page/1'>1</a>
<a href='webpage-category/page/2'>2</a>
</div>"""
soup = BeautifulSoup(html)
link = soup.find('div', {'class': 'pagination'}).find('a')['href']
print '/'.join(link.split('/')[:-1])
prints:
webpage-category/page
Just FYI, speaking about the code you've provided - you can use [next()][-1] instead of a list comprehension:
s = next(l['href'] for link in soup.find_all('div', class_='pagination')
for l in link.find_all('a') if not re.search('pageSub', l['href']))
UPD (using the website link provided):
import urllib2
from bs4 import BeautifulSoup
url = "http://www.hdwallpapers.in/cars-desktop-wallpapers/page/2"
soup = BeautifulSoup(urllib2.urlopen(url))
links = soup.find_all('div', {'class': 'pagination'})[1].find_all('a')
print next('/'.join(link['href'].split('/')[:-1]) for link in links
if link.text.isdigit() and link.text != "1")
