BeatifulSoup4 get_text still has javascript

Question

I’m trying to remove all the html/javascript using bs4, however, it doesn’t get rid of javascript. I still see it there with the text. How can I get around this?

I tried using nltk which works fine however, clean_html and clean_url will be removed moving forward. Is there a way to use soups get_text and get the same result?

I tried looking at these other pages:

BeautifulSoup get_text does not strip all tags and JavaScript

Currently i’m using the nltk’s deprecated functions.

EDIT

Here’s an example:

import urllib
from bs4 import BeautifulSoup

url = "http://www.cnn.com"
html = urllib.urlopen(url).read()
soup = BeautifulSoup(html)
print soup.get_text()

I still see the following for CNN:

$j(function() {
"use strict";
if ( window.hasOwnProperty('safaripushLib') && window.safaripushLib.checkEnv() ) {
var pushLib = window.safaripushLib,
current = pushLib.currentPermissions();
if (current === "default") {
pushLib.checkPermissions("helloClient", function() {});
}
}
});

/*globals MainLocalObj*/
$j(window).load(function () {
'use strict';
MainLocalObj.init();
});

How can I remove the js?

Only other options I found are:

The problem with html2text is that it’s really really slow at times, and creates noticable lag, which is one thing nltk was always very good with.

Answer 1

Based partly on Can I remove script tags with BeautifulSoup?

import urllib
from bs4 import BeautifulSoup

url = "http://www.cnn.com"
html = urllib.urlopen(url).read()
soup = BeautifulSoup(html)

# kill all script and style elements
for script in soup(["script", "style"]):
    script.decompose()    # rip it out

# get text
text = soup.get_text()

# break into lines and remove leading and trailing space on each
lines = (line.strip() for line in text.splitlines())
# break multi-headlines into a line each
chunks = (phrase.strip() for line in lines for phrase in line.split("  "))
# drop blank lines
text = 'n'.join(chunk for chunk in chunks if chunk)

print(text)

To prevent encoding errors at the end…

import urllib
from bs4 import BeautifulSoup

url = url
html = urllib.urlopen(url).read()
soup = BeautifulSoup(html)

# kill all script and style elements
for script in soup(["script", "style"]):
    script.extract()    # rip it out

# get text
text = soup.get_text()

# break into lines and remove leading and trailing space on each
lines = (line.strip() for line in text.splitlines())
# break multi-headlines into a line each
chunks = (phrase.strip() for line in lines for phrase in line.split("  "))
# drop blank lines
text = 'n'.join(chunk for chunk in chunks if chunk)

print(text.encode('utf-8'))
