want to get all the java script file from html using bs4 - python-2.7

from bs4 import BeautifulSoup
import re
import HTMLParser
import urllib
url = raw_input('enter - ')
html = urllib.urlopen(url).read()
soup = BeautifulSoup(html)
scripts=soup.find_all('script')
for tag in scripts:
try:
Script = tag["src"]
print Script
except:
print "No source"
using this code I m not getting all the java script from html document.

I have checked your code and it seems that you are getting all the javascript. At least you check for all the tags. Of course some of the javascript may be directly embedded into the html and thereby won't have a src attribute. Merely the actual javascript between the <script>...</script> tags. You can get the javscript between these embedded tags using tag.contents in your loop.
Furthermore, I would advise to specify a parser. By default bs4 uses html.parser. Other parsers may perform better/differently. Check out: http://www.crummy.com/software/BeautifulSoup/bs4/doc/#installing-a-parser

from bs4 import BeautifulSoup
import urllib2
r = urllib2.urlopen('<your url>').read()
soup = BeautifulSoup(r, 'html.parser')
for s in soup.findAll('script'):
print s.get('src')

How to select text without the html code when web scraping in Python (2.7)?

The below code returns the text including the html code. However, I need to retrieve the text only so that it can be loaded nicely into a pd.DataFrame. How do I 'strip' the text?
#importing packages
from bs4 import BeautifulSoup
import requests
#url
url = "https://example.com/this_is_just_an_example"
#request to get text from url
r = requests.get(url).text
#create soup version of the text
soup = BeautifulSoup(r, features="lxml")
#create a list to store the text
MyHeadlines= []
#appended the text to list Names
for i in soup.find_all('h3', {'class': 'headline'}):
MyHeadlines.append(str(i))
You can easily do this with some simple regex:
import re
CLEAN_TEXT = re.sub('<[^<]+?>', '', YOUR_TEXT)
Enjoy!

Remove img tags from xml with BeautifulSoup

It's my first time using Python and BeautifulSoup. The thing is I'm doing a migration of all articles within a blog from one website to another, and to perform this, I'm extracting certain information from a xml file; the last part of my code tells to extract only the text between the position 0 and 164 from the meta tag, so this way it can appear on google SERP as they want to appear.
The problem here is some articles from the blog has img tags on the first lines inside the tag and I want to remove them, including the src attributes so the code can grab just the text after those img tags.
I tried to solve it in many ways but I did not succeed.
Here is my code:
from bs4 import BeautifulSoup
from urllib2 import urlopen
import csv
import sys
import re
reload(sys)
sys.setdefaultencoding('utf8')
base_url = ("http://pimacleanpro.com/blog?rss=true")
soup = BeautifulSoup(urlopen(base_url).read(),"xml")
titles = soup("title")
slugs = soup("link")
bodies = soup("description")
with open("blog-data.csv", "w") as f:
fieldnames = ("title", "content", "slug", "seo_title", "seo_description","site_id", "page_path", "category")
output = csv.writer(f, delimiter=",")
output.writerow(fieldnames)
for i in xrange(len(titles)):
output.writerow([titles[i].encode_contents(),bodies[i].encode_contents(formatter=None),slugs[i].get_text(),titles[i].encode_contents(),bodies[i].encode_contents(formatter=None)[4:164]])
print "Done writing file"
any help will be appreciated.
Here's a Python 2.7 example that I think does what you want:
from bs4 import BeautifulSoup
from urllib2 import urlopen
from xml.sax.saxutils import unescape
base_url = ("http://pimacleanpro.com/blog?rss=true")
# Unescape to allow BS to parse the <img> tags
soup = BeautifulSoup(unescape(urlopen(base_url).read()))
titles = soup("title")
slugs = soup("link")
bodies = soup("description")
print bodies[2].encode_contents(formatter=None)[4:164]
# Remove all 'img' tags in all the 'description' tags in bodies
for body in bodies:
for img in body("img"):
img.decompose()
print bodies[2].encode_contents(formatter=None)[4:164]
# Proceed to writing to CSV, etc.
The first print statement outputs the following:
<img src='"http://ekblog.s3.amazonaws.com/contentp/wp-content/uploads/2018/09/03082910/decoration-design-detail-691710-300x221.jpg"'><br>
<em>Whether you are up
While the second one after removing the <img> tags is as follows:
<em>Whether you are upgrading just one room or giving your home a complete renovation, it’s likely that your first thought is to choose carpet for all of
Of course you could just remove all image tags in the soup object before creating titles, slugs, or bodies if they're not of interest to you:
for tag in soup("img"):
tag.decompose()

Using beautifulsoup to extract data from html content - HTML Parsing

The contents of my script using beautifulsoup library is as follows:
<meta content="Free" itemprop="price" />
and
<div class="content" itemprop="datePublished">November 4, 2013</div>
I would want to pull the words Free and November 4, 2013 from that output. Will using a Regex help or does beautifulsoup has any such attributes that will pull out this directly? Here is the code I used below:
from BeautifulSoup import BeautifulSoup
import urllib
import re
pageFile = urllib.urlopen("https://play.google.com/store/apps/details?id=com.ea.game.fifa14_na")
pageHtml = pageFile.read()
pageFile.close()
soup = BeautifulSoup("".join(pageHtml))
item = soup.find("meta", {"itemprop":"price"})
print item
items = soup.find("div",{"itemprop":"datePublished"})
print items
Ok got it! Just access the values by the following method(for the above case):
from BeautifulSoup import BeautifulSoup
import urllib
pageFile = urllib.urlopen("https://play.google.com/store/apps/details?id=com.ea.game.fifa14_na")
pageHtml = pageFile.read()
pageFile.close()
soup = BeautifulSoup("".join(pageHtml))
item = soup.find("meta", {"itemprop":"price"}) # meta content="Free" itemprop="price"
print item['content']
items = soup.find("div",{"itemprop":"datePublished"})
print items.string
No need to add regex. Just a read up through the documentation would help.

Cant find table with soup.findAll('table') using BeautifulSoup in python

Im using soup.findAll('table') to try to find the table in an html file, but it will not appear.
The table indeed exists in the file, and with regex Im able to locate it this way:
import sys
import urllib2
from bs4 import BeautifulSoup
import re
webpage = open(r'd:\samplefile.html', 'r').read()
soup = BeautifulSoup(webpage)
print re.findall("TABLE",webpage) #works, prints ['TABLE','TABLE']
print soup.findAll("TABLE") # prints an empty list []
I know I am correctly generating the soup since when I do:
print [tag.name for tag in soup.findAll(align=None)]
It will correctly print tags that it finds. I already tried also with different ways to write "TABLE" like "table", "Table", etc.
Also, if I open the file and edit it with a text editor, it has "TABLE" on it.
Why beautifulsoup doesnt find the table??
Context
python 2.x
BeautifulSoup HTML parser
Problem
bsoup findall does not return all the expected tags, or it returns none at all, even though the user knows that the tag exists in the markup
Solution
Try specifying the exact parser when initializing the BeautifulSoup constructor
## BEFORE
soup = BeautifulSoup(webpage)
## AFTER
soup = BeautifulSoup(webpage, "html5lib")
Rationale
The target markup may include mal-formed HTML, and there are varying degrees of success with different parsers.

How to use lxml to get a message from a website?

At exam.com is not about the weather:
Tokyo: 25°C
I want to use Django 1.1 and lxml to get information at the website. I want to get information that is of "25" only.
HTML exam.com structure as follows:
<p id="resultWeather">
<b>Weather</b>
Tokyo:
<b>25</b>°C
</p>
I'm a student. I'm doing a small project with my friends. Please explain to me easily understand. Thank you very much!
BeautifulSoup is more suitable for html parsing than lxml.
something like this can be helpful:
def get_weather():
import urllib
from BeautifulSoup import BeautifulSoup
data = urllib.urlopen('http://exam.com/').read()
soup = BeautifulSoup(data)
return soup.find('p', {'id': 'resultWeather'}).findAll('b')[-1].string
get page contents with urllib, parse it with BeautifulSoup, find P with id=resultWeather, find last B in our P and get it's content
