How to retrieve URLs under a certain property using BeautifulSoup in Python? - python

I am trying to retrieve urls under a certain property. The current code I have is
import urllib
import lxml.html
url = 'https://play.acast.com/s/jeg-kan-ingenting-om-vin/33.hvorforercheninblancfraloireogsor-afrikaikkelengerpafolksradar-'
connection = urllib.urlopen(url)
dom = lxml.html.fromstring(connection.read())
links = []
for link in dom.xpath('//meta/#content'): # select the url in href for all a tags(links)
if 'mp3' in link:
links.append(link)
output = set(links)
for i in output:
print(i)
This outputs 2 links which is not what I want.
https://sphinx.acast.com/jeg-kan-ingenting-om-vin/33.hvorforercheninblancfraloireogsor-afrikaikkelengerpafolksradar-/media.mp3
https://sphinx.acast.com/jeg-kan-ingenting-om-vin/33.hvorforercheninblancfraloireogsor-afrikaikkelengerpafolksradar-r/media.mp3
What I would like to do is to get 'only' the URL link that is under og:audio property. Not og:audio:secure_url property.
How do I accomplish this?

To only select a tag where the property="og:audio" and not property="og:audio:secure_url", you can use an [attribute=value]
CSS selector. In your case it would be: [property="og:audio"].
Since you tagged beautifulsoup, you can do it as follows:
soup = BeautifulSoup(connection.read(), "html.parser")
for tag in soup.select('[property="og:audio"]'):
print(tag["content"])
Output:
https://sphinx.acast.com/jeg-kan-ingenting-om-vin/33.hvorforercheninblancfraloireogsor-afrikaikkelengerpafolksradar-/media.mp3

A better way would be to study the XHR calls in the Network tab when you inspect the page. In the response of https://feeder.acast.com/api/v1/shows/jeg-kan-ingenting-om-vin/episodes/33.hvorforercheninblancfraloireogsor-afrikaikkelengerpafolksradar-?showInfo=true the url key is what you are looking for.

How to print the first google search result link using bs4?

I'm a beginner in python, I'm trying to get the first search result link from google which was stored inside a div with class='yuRUbf' using beautifulsoup. When I run the script output is 'None' what is the error here.
import requests
import bs4
url = 'https://www.google.com/search?q=site%3Astackoverflow.com+how+to+use+bs4+in+python&sxsrf=AOaemvKrCLt-Ji_EiPLjcEso3DVfBUmRbg%3A1630215433722&ei=CR0rYby7K7ue4-EP7pqIkAw&oq=site%3Astackoverflow.com+how+to+use+bs4+in+python&gs_lcp=Cgdnd3Mtd2l6EAM6BwgAEEcQsAM6BwgjELACECc6BQgAEM0CSgQIQRgAUMw2WPh_YLiFAWgBcAJ4AIABkAKIAd8lkgEHMC4xMC4xM5gBAKABAcgBCMABAQ&sclient=gws-wiz&ved=0ahUKEwj849XewdXyAhU7zzgGHW4NAsIQ4dUDCA8&uact=5'
request_result=requests.get( url )
soup = bs4.BeautifulSoup(request_result.text,"html.parser")
productDivs = soup.find("div", {"class": "yuRUbf"})
print(productDivs)
Let's see:

"useragent"
}
html = requests.get('https://www.google.com/search?q=hello', headers=headers).text

# locating div element with a tF2Cxc class
# calling for <a> tag and then calling for 'href' attribute
link = soup.find('div', class_='tF2Cxc').a['href']
print(link)
output:
'''

As you want first google search in which class name which you are looking for might be differ with name so first you can first find manually that link so it will be easy to identify
import requests

soup = bs4.BeautifulSoup(request_result.text,"html.parser")
Using select method:
I have used css selector method in which it identifies all matching
divs and from list i have taken from index postion 1
And than i have use select_one to get a tag and find href
according to it!
main_data=soup.select("div.ZINbbc.xpd.O9g5cc.uUPGi")[1:]
main_data[0].select_one("a")['href'].replace("/url?q=","")
Using find method:
main_data=soup.find_all("div",class_="ZINbbc xpd O9g5cc uUPGi")[1:]
main_data[0].find("a")['href'].replace("/url?q=","")
Output [Same for Both the Case]:

Web scraping an xml page in python?

I am confused as to how I would scrape all the links (that only contain the string "mp3") off a given xml page. The following code only returns empty brackets:
# Import required modules
from lxml import html
import requests
# Request the page
page = requests.get('https://feeds.megaphone.fm/darknetdiaries')
# Parsing the page
# (We need to use page.content rather than
# page.text because html.fromstring implicitly
# expects bytes as input.)
tree = html.fromstring(page.content)
# Get element using XPath
buyers = tree.xpath('//enclosure[#url="mp3"]/text()')
print(buyers)
Am I using #url wrong?
The links I am looking for:
Any help would be greatly appreciated!
What happens?
The following xpath wont work, as you mentioned it is the use of #url and also text()
//enclosure[#url="mp3"]/text()
Solution
The attribute url in any //enclosure should contain mp3 and then returned /#url
Change this line:
buyers = tree.xpath('//enclosure[#url="mp3"]/text()')
to
buyers = tree.xpath('//enclosure[contains(#url,"mp3")]/#url')
Output

It does not directly answer your question, but you could check out BeautifulSoup as an alternative (and it has an option to use lxml under the hoop too).
import lxml # early failure if not installed
from bs4 import BeautifulSoup
import requests
# Request the page
page = requests.get('https://feeds.megaphone.fm/darknetdiaries')
# Parse
soup = BeautifulSoup(page.text, 'lxml')
# Find
#mp3 = [link['href'] for link in soup.find_all('a') if 'mp3' in link['href']]
# UPDATE - correct tag and attribute
mp3 = [link['url'] for link in soup.find_all('enclosure') if 'mp3' in link['url']]

How to extract the link of the first gallery on imgur using BS4 and urllib

I am trying to extract the gallery link of the first result on an imgur search.
theurl = "https://imgur.com/search?q=" +text
thepage = urlopen(theurl)
soup = BeautifulSoup(thepage,"html.parser")
link = soup.findAll('a',{"class":"image-list-link"})[0].decode_contents()
Here is what is being displayed for link:
I am mainly trying to get the href value from only this section (the first result for the search)
Here is what the inspect element looks like:
Actually, it's pretty easy to accomplish what you're trying to do. As shown in the image, the href of first image (or any image for that matter) is located inside the <a> tag with the attribute class="image-list-link". So, you can use the find() function, which returns the first match found. And then, use ['href'] to get the link.
Code:
import requests
from bs4 import BeautifulSoup
r = requests.get('https://imgur.com/search?q=python')
soup = BeautifulSoup(r.text, 'lxml')
first_image_link = soup.find('a', class_='image-list-link')['href']
print(first_image_link)
# /gallery/AxKwQ2c
If you want to get the links for all the images, you can use a list comprehension.
all_image_links = [a['href'] for a in soup.find_all('a', class_='image-list-link')]

How to get the Wikidata item's Q-number of a wikipedia page by BS4?

You can find namely Wikidata item under Tools in the left sidebar of this Wikipedia page. If you hover on that , you can find the link address as below with Q-number at the end.
https://www.wikidata.org/wiki/Special:EntityPage/Q15112.
How can i extract the Q-number?
from bs4 import BeautifulSoup
import requests
getUrl= 'https://en.wikipedia.org/wiki/Ariyalur_district'
url = getUrl
content = requests.get(url).content
soup = BeautifulSoup(content,'lxml')
#extracting page title
firstHeading = soup.find('h1',{'class' : 'firstHeading'})
print(firstHeading.text +'~')
Upto this, my code is good. I tried to get the Q-number by the below code but i can't. Kindly, guide me.
QNumber = soup.find('li','t-wikibase')
print(QNumber)
How can get the Q-number?
You'll need to explicitly specify the selector you're looking for, that's id in this case:
In [1601]: QNumber = soup.find('li', {'id' : 't-wikibase'})
In [1604]: QNumber.a['href']
Out[1604]: 'https://www.wikidata.org/wiki/Special:EntityPage/Q15112'
If you just want the number at the end of this link, you can do this:
In [1605]: QNumber.a['href'].rsplit('/')[-1]
Out[1605]: 'Q15112'

How to find specific video html tag using beautiful soup?

Does anyone know how to use beautifulsoup in python.
I have this search engine with a list of different urls.
I want to get only the html tag containing a video embed url. and get the link.
example
import BeautifulSoup
html = '''https://archive.org/details/20070519_detroit2'''
#or this.. html = '''http://www.kumby.com/avatar-the-last-airbender-book-3-chapter-5/'''
#or this... html = '''https://www.youtube.com/watch?v=fI3zBtE_S_k'''
soup = BeautifulSoup.BeautifulSoup(html)
what should I do next . to get the html tag of video, or object or the exact link of the video..
I need it to put it on my iframe. i will integrate the python to my php. so getting the link of the video and outputting it using the python then i will echo it on my iframe.
You need to get the html of the page not just the url
use the built-in lib urllib like this:
import urllib
from bs4 import BeautifulSoup as BS
url = '''https://archive.org/details/20070519_detroit2'''
#open and read page
page = urllib.urlopen(url)
html = page.read()
#create BeautifulSoup parse-able "soup"
soup = BS(html)
#get the src attribute from the video tag
video = soup.find("video").get("src")
also with the site you are using i noticed that to get the embed link just change details in the link to embed so it looks like this:
https://archive.org/embed/20070519_detroit2
so if you want to do it to multiple urls without having to parse just do something like this:
url = '''https://archive.org/details/20070519_detroit2'''
spl = url.split('/')
spl[3] = 'embed'
embed = "/".join(spl)
print embed
EDIT
to get the embed link for the other links you provided in your edit you need to look through the html of the page you are parsing, look until you fint the link then get the tag its in then the attribute
for
'''http://www.kumby.com/avatar-the-last-airbender-book-3-chapter-5/'''
just do
soup.find("iframe").get("src")
the iframe becuase the link is in the iframe tag and the .get("src") because the link is the src attribute
You can try the next one because you should learn how to do it if you want to be able to do it in the future :)
Good luck!
You can't parse a URL. BeautifulSoup is used to parse an html page. Retrieve the page first:
import urllib2
data = urllib2.ulropen("https://archive.org/details/20070519_detroit2")
html = data.read()
Then you can use find, and then take the src attribute:
soup = BeautifulSoup(html)
video = soup.find('video')
src = video['src']
this is a one liner to get all the downloadable MP4 file in that page, in case you need it.
import bs4, urllib2
url = 'https://archive.org/details/20070519_detroit2'
soup = bs4.BeautifulSoup(urllib2.urlopen(url))
links = [a['href'] for a in soup.find_all(lambda tag: tag.name == "a" and '.mp4' in tag['href'])]
print links
Here are the output:
['/download/20070519_detroit2/20070519_detroit_jungleearth.mp4',
'/download/20070519_detroit2/20070519_detroit_sweetkissofdeath.mp4',
'/download/20070519_detroit2/20070519_detroit_goodman.mp4',
...
'/download/20070519_detroit2/20070519_detroit_wilson_512kb.mp4']
These are relative links and you and put them together with the domain and you get absolute path.
