How to change the class of a HTML <div> using BeautifulSoup? - python

I'm modifying a HTML file using Python and BeautifulSoup,and I can change the content of headers,but I couldn't find a way to change the class of a div. My goal is to turn
<div id="div1" class="blue_titles">test</div>
into:
<div id="div1" class="green_titles">test</div>
I looked up and down the docs,but to no avail. It's probably right on my face,but I can't find it.Thanks in advance!

You can simply assign the new value to the key class:
from bs4 import BeautifulSoup
soup = BeautifulSoup("""<div id="div1" class="blue_titles">test</div>""", "lxml")
soup.find("div")['class'] = "green_titles"
soup
# <html><body><div class="green_titles" id="div1">test</div></body></html>

From the following piece of code, I want to create a loop that allows me
to extract TEXT if and only if div class = ELEMENT 4 AND svg class = ELEMENT 5 (because there are other different ones)
thank you for your help

you'll need to import urllib2 or some other library that allows you to fetch a urls html structure. Then you need to import beautiful soup as well. Scrape the url and store into a variable. Then reformat the output in any way that serves your needs.
For example:
import urllib2
from bs4 import beautifulSoup
page = urlopen("the_url")
content = BeautifulSoup(page.read().decode("utf-8")) #decode data (utf-8)
filter = content.find_all("div") #finds all div elements in the body
Then you could use regexp to find the actual text inside the element.
Good luck on your assignment!

Scrapy: how to get links to users?

I'm trying to get links to group members:
response.css('.text--ellipsisOneLine::attr(href)').getall()
Why isn't this working?
html:
<div class="flex flex--row flex--noGutters flex--alignCenter">
<div class="flex-item _memberItem-module_name__BSx8i">
<a href="/ru-RU/Connect-IT-Meetup-in-Chisinau/members/280162178/profile/?returnPage=1">
<h4 class="text--bold text--ellipsisOneLine">Liviu Cernei</h4>
</a>
</div>
</div>
Your selector isn't working because you are looking for a attribute (href) that this element doesn't have.
response.css('.text--ellipsisOneLine::attr(href)').getall()
This selector is searching for href inside elements of class text--ellipsisOneLine. In your HTML snippet that class matches only with this:
<h4 class="text--bold text--ellipsisOneLine">Liviu Cernei</h4>
As you can see, there is no href attribute. Now, if you want the text between this h4 element you need to use ::text pseudo-element.
response.css('.text--ellipsisOneLine::text').getall()
Read more here.
I realize that this isn't scrapy, but personally for web scraping I use the requests module and BeautifulSoup4, and the following code snippet will get you a list of users with the aforementioned modules:
import requests
from bs4 import BeautifulSoup
response = requests.get('https://www.meetup.com/ru-RU/Connect-IT-Meetup-in-Chisinau/members/')
if response.status_code == 200:
html_doc = response.text
html_source = BeautifulSoup(html_doc, 'html.parser')
users = html_source.findAll('h4')
for user in users:
print(user.text)
css:
response.css('.member-item .flex--alignCenter a::attr(href)').getall()

How to extract data(text) using beautiful soup when they are in the same class?

I'm working on a personal project where I scrape data from a website. I'm trying to use beautiful soup to do this but I came across data in the same class but a different attribute. For example:
<div class="pi--secondary-price">
<span class="pi--price">$11.99 /<abbr title="Kilogram">kg</abbr></span>
<span class="pi--price">$5.44 /<abbr title="Pound">lb.</abbr></span>
</div>
How do I just get $11.99/kg? Right now I'm getting
$11.99 /kg
$5.44 /lb.
I've done x.select('.pi--secondary-price') but it returns both prices. How do I only get 1 price ($11.99 /kg)?
You could first get the <abbr> tag and then search for the respective parent tag. Like this:
from bs4 import BeautifulSoup
html = '''
<div class="pi--secondary-price">
<span class="pi--price">$11.99 /<abbr title="Kilogram">kg</abbr></span>
<span class="pi--price">$5.44 /<abbr title="Pound">lb.</abbr></span>
</div>
'''
soup = BeautifulSoup(html, 'html.parser')
kg = soup.find(title="Kilogram")
print(kg.parent.text)
This gives you the desired output $11.99 /kg. For more information, see the BeautifulSoup documentation.

Scraping div with a data- attribute using Python and BeautifulSoup

I have to scrape a web page using BeautifulSoup in python.So to extract the complete div which hass the relavent information and looks like the one below:
<div data-v-24a74549="" class="row row-mg-mod term-row">
I wrote soup.find('div',{'class':'row row-mg-mod term-row'}).
But it is returning nothing.I guess it is something to do with this data-v value.
Can someone tell the exact syntaxof scraping this type of data?
Give this a try:
from bs4 import BeautifulSoup
content = """
<div data-v-24a74549="" class="row row-mg-mod term-row">"""
soup = BeautifulSoup(content,'html.parser')
for div in soup.find_all("div", {"class" : "row"}):
print(div)

How to find element based on text ignore child tags in beautifulsoup

I am looking for a solution using Python and BeautifulSoup to find an element based on the inside text. For example:
<div> <b>Ignore this text</b>Find based on this text </div>
How can I find this div? Thanks for you helps!
You can use .find with the text argument and then use findParent to the parent element.
Ex:
from bs4 import BeautifulSoup
s="""<div> <b>Ignore this text</b>Find based on this text </div>"""
soup = BeautifulSoup(s, 'html.parser')
t = soup.find(text="Find based on this text ")
print(t.findParent())
Output:
<div> <b>Ignore this text</b>Find based on this text </div>
try it , it is like example but it works
from bs4 import BeautifulSoup
html="""
<div> <b>Ignore this text</b>Find based on this text </div>
"""
soup = BeautifulSoup(html, 'lxml')
s = soup.find('div')
for child in s.find_all('b'):
child.decompose()
print(s.get_text())
Output
Find based on this text
