Need to get a specific class exists in HTML body - python-3.x

I am trying to check if class = "special-price" exists in below code.
Here is html code :
<div class="product-shop">
<div class="f-fix">
<h2 class="product-name newname"> Xiaomi Mi Band 2 Strap (Black with White Border) </h2>
<!--product price-->
<div class="text-center ">
<div class="price-box">
<p class="old-price"> <span class="price-label">Regular Price:</span >
<span class = "price" id = "old-price-8846" > ৳200 </span>
</p >
<p class = "special-price" >
<span class = "price-label"> Special Price </span>
<span class="price" itemprop="price" content="149" id="product-price-8846"> ৳149 </span>
</p>
</div>
</div >
</div>
I am using Scrapy with python. After checking if the class found I need to collect text of class="price".

Did you try something like:
if response.css('.special-price'):
price = response.css('.price::text').get() # or do whatever you need
or for short:
price = response.css('.special-price .price::text').get()
it will give you None in case there is no element with special-price class.

Web-scraping with Python 3 BeautifulSoup library

Playing with web-scraping in Python 3. I m trying to web-scrape the following HTML page using the BeautifulSoup library in Python 3.
<div class="container">
<div item-id="1" class="container1 item details">
<div class="item-name">
<div class="item-business-name">
<h3>My Business #1</h3>
</div>
</div>
<div class="item-location">
<div class="item-address">
<p>My Address #1</p>
</div>
</div>
<div class="item-contact">
<div class="item-email">
<p>My Email #1</p>
</div>
</div>
</div>
<div item-id="2" class="container2 item details">
<div class="item-name">
<div class="item-business-name">
<h3>My Business #2</h3>
</div>
</div>
<div class="item-location">
<div class="item-address">
<p>My Address #2</p>
</div>
</div>
<div class="item-contact">
<div class="item-email">
<p>My Email #2</p>
</div>
</div>
</div>
</div>
As the naming pattern of the required container(e.g. div item-id="1" class="container1 item details") changes for each item, I would appreciate a piece of advice on how to scrape item-business-name, item-address, item-contact for all items. There are 100 items on the page; hence, the last container is div item-id="100" class="container100 item details"
What is the best way to get all the items in the list at the "container 1-100" level, and after that I know how to get each item :)
I was thinking of something like:
n = 0
while n < 101
item = soup.find_all(class_=f"container{n} item details")
n = n + 1
print(item)
Unfortunately, it does not give me the required list.
You don't have to use any number in id or class names. Just use zip() function to tie all information for the contact together
Variable txt contains HTML string from your question:
from bs4 import BeautifulSoup
soup = BeautifulSoup(txt, 'html.parser')
out = []
for name, address, email in zip(soup.select('.item-business-name'),
soup.select('.item-address'),
soup.select('.item-email')):
out.append([name.get_text(strip=True), address.get_text(strip=True), email.get_text(strip=True)])
# pretty print all rows:
for no, row in enumerate(out, 1):
print('{}.'.format(no), ('{:<20}'*3).format(*row))
Prints:
1. My Business #1 My Address #1 My Email #1
2. My Business #2 My Address #2 My Email #2

Python web scraping style content

I just want to pull data from HTML by using python.(I need data = 20%)
Any help on this would be greatly appreciated.
<div class="ratings-container">
<div class="ratings">
<div class="ratings active" style="width: 20%"></div>
</div>
</div>
I don't know how to get the style content. The following similar code's result is NULL:
mratingNew = (tag.findAll('div',attrs={"class":"ratings active"}))
for i in range(len(muserName)):
print(mratingNew[i].['style'])
You can get width with using find and can split it according to :
from bs4 import BeautifulSoup
html = '''<div class="ratings-container">
<div class="ratings">
<div class="ratings active" style="width: 20%"></div>
</div>
</div>'''
soup = BeautifulSoup(html,"html.parser")
finddiv = soup.find('div',attrs={'class':'ratings active'})
style = finddiv['style']
style = style.split(':',1)[-1]
print style
OUTPUT :
20%
If you have more than one width with the same class name like :
html = '''<div class="ratings-container">
<div class="ratings">
<div class="ratings active" style="width: 20%"></div>
<div class="ratings active" style="width: 40%"></div>
<div class="ratings active" style="width: 30%"></div>
</div>
</div>'''
You need to use findAll and split it one by one
find_last_div = soup.findAll('div',attrs={'class':'ratings active'})
for width_value in find_last_div:
width_Get = width_value['style'].split(':',1)[-1]
print width_Get
OUTPUT :
20%
40%
30%

Div of Products With Price Slash
div class="products-info">
<h2 class="title"><span class="brand ">Apple </span> <span class="name" dir="ltr">IPhone X 5.8-Inch HD (3GB,64GB ROM) IOS 11, 12MP + 7MP 4G Smartphone - Silver</span></h2>

Div of Products with No Price Slash
div class="products-info">
<h2 class="title"><span class="brand ">Apple </span> <span class="name" dir="ltr">IPhone X 5.8-Inch HD (3GB,64GB ROM) IOS 11, 12MP + 7MP 4G Smartphone - Silver</span></h2>
<div class="price-container clearfix">
<span class="price-box ri">
<span class="price ">
<span data-currency-iso="NGN">₦</span>
<span dir="ltr" data-price="388990">388,990</span>
</span>
</span>
</div>
div
Now this is my exact Question
i want to know how to select only the parent divs i.e
div class="price-container clearfix"> that also contains any of these children span classes
span class="price -old "> or
span class="sale-flag-percent">
Thank you all
One solution would be get all <div class="price-container clearfix"> and iterate, checking with the string of the whole element that your keywords exist.
But a better solution would be to use conditionals with xpath:
from lxml import html
htmlst = 'your html'
tree=html.fromstring(htmlst)
divs = tree.xpath('//div[#class="price-container clearfix" and .//span[#class = "price -old " or #class = "sale-flag-percent"] ]')
print(divs)
This get all divs where class="price-container clearfix" and then check if contains span with the searched classes.

How to get data form website using BeautifulSoup Python?

I have a problem to get the data from some page. This is part of my code:
for result in results:
street = result.find('p', attrs={'class':'size16'}).text
records.append((street))
print (street)
Website:
<div class="media-body pt5 pb10">
<div class="mb15">
<span class="map-item-city block mb0 colorgreen">City</span>
<p class="small mb20"> </p>
<p class="size16">street 98<br>phone. 22 721-56-70</p>
</div>
<div class="colorblack"><strong>open</strong></div>
<div class="mb20 size16">Mon.-Fr. 07.30-15.30</div>
<div class="mb15 ">
Result of my code:
ul. Bema 2phone. (32) 745 72 66-69 Wroclaw None
ul. 1 Maja 22/Vphone. 537-943-969 Olawa <p class="small mb20 colorgreen">Placowka partnerska</p>
I would like to separate or delete the text after a "br" tag. I need only 'street'
<p class="size16">street 98<br>phone. 22 721-56-70</p>
Can You help me?
Use previous_sibling like this:
from bs4 import BeautifulSoup
html = """
<div class="media-body pt5 pb10">
<div class="mb15">
<span class="map-item-city block mb0 colorgreen">Bronisze</span>
<p class="small mb20"> </p>
<p class="size16">Poznańska 98<br>tel. 22 721-56-70</p>
</div>
<div class="colorblack"><strong>Godziny otwarcia</strong></div>
<div class="mb20 size16">Pn.-Pt. 07.30-15.30</div>
<div class="mb15 ">
"""
result=BeautifulSoup(html, "lxml")
br = result.find('br')
print (br.previous_sibling)
Or if you want to narrow it down a bit:
street = result.find('p', attrs={'class':'size16'}).find('br').previous_sibling
print (street)
Outputs (in both cases)
Poznańska 98
From the documentation https://www.crummy.com/software/BeautifulSoup/bs4/doc/
.next_sibling and .previous_sibling
You can use .next_sibling and .previous_sibling to navigate between page elements that are on the same level of the parse tree:
from bs4 import BeautifulSoup
html = """
<div class="media-body pt5 pb10">
<div class="mb15">
<span class="map-item-city block mb0 colorgreen">Bronisze</span>
<p class="small mb20"> </p>
<p class="size16">Poznańska 98<br>tel. 22 721-56-70</p>
</div>
<div class="colorblack"><strong>Godziny otwarcia</strong></div>
<div class="mb20 size16">Pn.-Pt. 07.30-15.30</div>
<div class="mb15 ">
"""
soup=BeautifulSoup(html, "lxml")
for html_tag_div in soup.find_all('div', class_ = "media-body pt5 pb10"):
for html_tag_div_1 in html_tag_div.find_all('div', class_ = "mb15"):
for html_tag_2 in html_tag_div_1.find_all("p", class_ = "size16"):
for html_tag_3 in html_tag_2.find("br").previous_siblings:
print(html_tag_3.get_text())

How to create list of web elements?

I am trying to make a list of web elements, but it can not seem to find the elements on the web page, although did worked 3 days ago and i can not find any changes in the web page.
this is the html code :
<li id="wlg_41410" class="leagueWindow " dataid="41410">
<h5 style="cursor: pointer; cursor: hand;" onclick="TodaysEventsLeagueWindow.minimizeRestoreClick(41410)">Europa League</h5>
<div class="bet_type select" id="_bet_types"></div>
<div class="bet_type lastscore ">
<h6>1X2 FT </h6>
<div class="types_bg">
<!--[if IE]> <div id="IEroot"> <![endif]-->
<div class="first_buttons_line">
</div>
<!--[if IE]> </div> <![endif]-->
<div class="time"> 23/11 | 18:00 </div>
<div class="bets ml">
</div>
<div class="time"> 23/11 | 20:00 </div>
<div class="bets ml">
</div>
<div class="time"> 23/11 | 20:00 </div>
<div class="bets ml">
</div>
<div class="time"> 23/11 | 20:00 </div>
<div class="bets ml">
</div>
<div class="time"> 23/11 | 20:00 </div>
<div class="bets ml">
</div>
<div class="clr"></div>
</div>
</div> <span class="x" onclick="TodaysEventsLeagueWindow.closeLeagueWindow(41410)"></span>
</li>
i am trying to make a list from the <div class="bets ml"></div> elements
but keep getting the selenium.common.exceptions.StaleElementReferenceException: Message: stale element reference: element is not attached to the page document exception , as if selenium can't find the web element.
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.common.exceptions import StaleElementReferenceException
import time
driver.get("https://www.luckia.es/apuestas")
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it("sbtechBC"))
eventos_de_hoy = driver.find_element_by_id("today_event_btn")
eventos_de_hoy.click()
ligi_len = len(WebDriverWait(driver, 10).until(EC.presence_of_all_elements_located((By.CLASS_NAME, "leagueWindow "))))
print(ligi_len)
for index in range(ligi_len):
item = WebDriverWait(driver, 10).until(EC.presence_of_all_elements_located((By.CLASS_NAME, "leagueWindow ")))[index]
driver.execute_script("arguments[0].scrollIntoView(true);", item)
nume_liga = item.find_element_by_tag_name("h5").text
time.sleep(3)
print('try', nume_liga)
meci = item.find_elements_by_xpath("//*[#class='bets ml']")
print("there are", len(meci), "in one liga")
the reason for the index is that the iframe refreshes every 25 sec.
i also tried meci = item.find_elements_by_css_selector('.bets.ml') and meci = item.find_elements_by_class_name('ml')
Why should i be able to extract the <h5></h5> element and not the other elements?
From your code block, its pretty clear you have just managed to cover up the real issue through time.sleep(3) as follows :
nume_liga = item.find_element_by_tag_name("h5").text
time.sleep(3)
print('try', nume_liga)
While invoking print() for a text, I am not sure why time.sleep(3) was induced. So our main issue got covered up there. But as the List was already created, you are able to print('try', nume_liga)
But next, when you do meci = item.find_elements_by_xpath("//*[#class='bets ml']") you face a StaleElementReferenceException because the HTML DOM have changed.
A closer look into the <h5> tag reveals it have a onclick() event as :
<h5 style="cursor: pointer; cursor: hand;" onclick="TodaysEventsLeagueWindow.minimizeRestoreClick(41410)">Europa League</h5>
A wild guess, while invoking .text on <h5> tag, the HTML DOM changes.
Solution :
A possible solution with your current code block may be to use getAttribute("innerHTML") instead of .text. So your line of code will be :
nume_liga = item.find_element_by_tag_name("h5").get_attribute("innerHTML")
