Reading a html file - peterl - Aug-20-2018

Hi guys,

I'm trying to read an html file and then print it on IDLE. The issue is that IDLE replaces < to < and > to >. Does anyone know how to solve that?

Thank you

Do you mean you are reading the html from a website and want to save it to a file?

I am not sure what you mean when you say you are printing it in IDLE. IDLE is a text editor and an embedded python prompt. The only storage there is the actually file you save code to.

Quote:< to < and > to >

This is the code for < and > as HTML defines tags with them. &lessthan; and &greaterthan;

I have saved a website in my HD as html file and I try to use BeautifulSoup to scrape it.
the problem is that for some reason < gets replaces to < and > to >

example:
from bs4 import BeautifulSoup as soup
my_url = open('test2.html', 'r')
page_soup = soup(my_url, "html.parser")
print (page_soup)

You have to be careful when you save so you keep same encoding.
Use always Requests for reading site.

When shall give source to BS save it as bytes wb.

import requests

url = 'https://dataquestio.github.io/web-scraping-pages/simple.html'
response = requests.get(url)
with open('simple.html', 'wb') as f_out:
    f_out.write(response.content)

Read it from BS,now will BS handle Unicode which in this case is UTF-8.

bs4 Wrote:Beautiful Soup uses a sub-library called Unicode, Dammit to detect a document’s encoding

from bs4 import BeautifulSoup

my_url = open('simple.html')
page_soup = BeautifulSoup(my_url, "html.parser")
print(page_soup)

Output:<!DOCTYPE html>

<html>
<head>
<title>A simple example page</title>
</head>
<body>
<p>Here is some simple content for this page.</p>
</body>
</html>

Read it with Requests alone then use text

import requests

url = 'https://dataquestio.github.io/web-scraping-pages/simple.html'
response = requests.get(url)

Usage:

# See that requests always get site encoding back
>>> response.encoding
'utf-8'

>>> print(response.text)
<!DOCTYPE html>
<html>
    <head>
        <title>A simple example page</title>
    </head>
    <body>
        <p>Here is some simple content for this page.</p>
    </body>
</html>

Requests and BS together.

import requests
from bs4 import BeautifulSoup

url = 'https://dataquestio.github.io/web-scraping-pages/simple.html'
url_get = requests.get(url)
soup = BeautifulSoup(url_get.content, 'html.parser')
print(soup.find('title').text)

Output:
A simple example page
