I want to extract specific URLs from an HTML page.
from urllib2 import urlopen
import re
from bs4 import BeautifulSoup
url = http://bassrx.tumblr.com/tagged/tt # nsfw link
page = urlopen(url)
html = page.read() # get the html from the url
# this works without BeautifulSoup, but it is slow:
image_links = re.findall("src.\"(\S*?media.tumblr\S*?tumblr_\S*?jpg)", html)
print image_links
The output of the above is exactly the URL, nothing else: http://38.media.tumblr.com/tumblr_ln5gwxHYei1qi02clo1_500.jpg
The only downside is it is very slow.
BeautifulSoup is extremely fast at parsing HTML, so that's why I want to use it.
The urls that I want are actually the img src. Here's a snippet from the HMTL that contains that information that I want.
<div class="media"><a href="http://bassrx.tumblr.com/image/85635265422">
<img src="http://38.media.tumblr.com/tumblr_ln5gwxHYei1qi02clo1_500.jpg"/>
</a></div>
So, my question is, how can I get BeautifulSoup to extract all of those 'img src' urls cleanly without any other cruft?
I just want a list of matching urls. I've been trying to use soup.findall() function, but cannot get any useful results.
from urllib2 import urlopen
from bs4 import BeautifulSoup
url = 'http://bassrx.tumblr.com/tagged/tt'
soup = BeautifulSoup(urlopen(url).read())
for element in soup.findAll('img'):
print(element.get('src'))
You can use div.media > a > img CSS selector to find img tags inside a which is inside a div tag with media class:
from urllib2 import urlopen
from bs4 import BeautifulSoup
url = "<url_here>"
soup = BeautifulSoup(urlopen(url))
images = soup.select('div.media > a > img')
print [image.get('src') for image in images]
In order to make the parsing faster you can use lxml parser:
soup = BeautifulSoup(urlopen(url), "lxml")
You need to install lxml module first, of course.
Also, you can make use of a SoupStrainer class for parsing only relevant part of the document.
Hope that helps.
Have a look a BeautifulSoup.find_all with re.compile mix
from urllib2 import urlopen
import re
from bs4 import BeautifulSoup
url = "http://bassrx.tumblr.com/tagged/tt" # nsfw link
page = urlopen(url)
html = page.read()
bs = BeautifulSoup(html)
a_tumblr = [a_element for a_element in bs.find_all(href=re.compile("media\.tumblr"))]
##[<link href="http://37.media.tumblr.com/avatar_df3a9e37c757_128.png" rel="shortcut icon"/>, <link href="http://37.media.tumblr.com/avatar_df3a9e37c757_128.png" rel="apple-touch-icon"/>]

I think you want to scrape a javascript website you can use selenium or any library
see this
I write the following code to extract price from webpage:
from urllib.request import urlopen
from bs4 import BeautifulSoup
url = "https://www.teleborsa.it/azioni/intesa-sanpaolo-isp-it0000072618-SVQwMDAwMDcyNjE4"
html = urlopen(url)
soup = BeautifulSoup(html,'lxml')
prize = soup.select('.h-price')
print(prize)
output is:
<span class="h-price fc0" id="ctl00_phContents_ctlHeader_lblPrice">1,384</span>
i want to extract 1,384 value.
Try this
document.getElementById("ctl00_phContents_ctlHeader_lblPrice").innerText
Or if you are having dynamic elements, you can iterate over each element and get innerText from it.
You can use .text property to get the desired text.
For example:
from urllib.request import urlopen
from bs4 import BeautifulSoup
url = "https://www.teleborsa.it/azioni/intesa-sanpaolo-isp-it0000072618-SVQwMDAwMDcyNjE4"
html = urlopen(url)
soup = BeautifulSoup(html,'lxml')
prize = soup.select_one('.h-price') # <- change to .select_one() to get only one element
print(prize.text) # <- use the .text property to get text of the tag
Prints:
1,384
Hello every one I'm new to beautifulsoup, I'm trying to write a function that will be able to extract second level urls from a given website.
For example if I have this website url : https://edition.cnn.com/ my function should be able to return
https://edition.cnn.com/world
https://edition.cnn.com/politics
https://edition.cnn.com/business
https://edition.cnn.com/health
https://edition.cnn.com/entertainment
https://edition.cnn.com/style
https://edition.cnn.com/travel
first I have tried this code to retrieve all links starting with the string of the url:
from bs4 import BeautifulSoup as bs4
import requests
import lxml
import re
def getLinks(url):
response = requests.get(url)
data = response.text
soup = bs4(data, 'lxml')
links = []
for link in soup.find_all('a', href=re.compile(str(url))):
links.append(link.get('href'))
return links
But then again the actual output is giving me all the links even links of articles which is not I'm looking for. is there a method that I can use to get what I want using regular expression or others.
The links are inside <nav> tag, so using CSS selector nav a[href] will select only links inside <nav> tag:
import requests
from bs4 import BeautifulSoup
url = 'https://edition.cnn.com'
soup = BeautifulSoup(requests.get(url).text, 'lxml')
for a in soup.select('nav a[href]'):
if a['href'].count('/') > 1 or '#' in a['href']:
continue
print(url + a['href'])
Prints:
https://edition.cnn.com/world
https://edition.cnn.com/politics
https://edition.cnn.com/business
https://edition.cnn.com/health
https://edition.cnn.com/entertainment
https://edition.cnn.com/style
https://edition.cnn.com/travel
https://edition.cnn.com/sport
https://edition.cnn.com/videos
https://edition.cnn.com/world
https://edition.cnn.com/africa
https://edition.cnn.com/americas
https://edition.cnn.com/asia
https://edition.cnn.com/australia
https://edition.cnn.com/china
https://edition.cnn.com/europe
https://edition.cnn.com/india
https://edition.cnn.com/middle-east
https://edition.cnn.com/uk
...and so on.
How can I get the content of an html tag with beautifulsoup? for example the content of <title> tag?
I tried:
from bs4 import BeautifulSoup
url ='http://www.websiteaddress.com'
soup = BeautifulSoup(url)
result = soup.findAll('title')
for each in result:
print(each.get_text())
But nothing happened. I'm using python3.
You need to fetch the website data first. You can do this with the urllib.request module. Note that HTML documents only have one title so there is no need to use find_all() and a loop.
from urllib.request import urlopen
from bs4 import BeautifulSoup
url ='http://www.websiteaddress.com'
data = urlopen(url)
soup = BeautifulSoup(data, 'html.parser')
result = soup.find('title')
print(result.get_text())
Is it possible to set up in beautifulSoup that I can print only links that has <img> inside its content?
Currently my code looks like this:
import urllib
import re
import mechanize
from bs4 import BeautifulSoup
import urlparse
url = "http://www.nytimes.com"
htmlcontent = urllib.urlopen(url)
soup = BeautifulSoup(htmlcontent)
for link in soup.find_all('a'):
print link.contents
which print outs all content inside links. But my true need is to print links that has <img> tags inside it content and I don't know how to do that...
any help is welcome
Just try to find img tag inside the link:
for link in soup.find_all('a'):
if link.find('img'):
print link
