How to Remove HTML Tags from Strings in Python?

Removing HTML Formatting from Strings in Python

Consider the task of extracting the contents of an HTML document without displaying the formatting tags. For instance, the HTML element some text should output only "some text," and hello should display "hello."

Solution

The built-in Python library provides a useful mechanism to achieve this goal:

For Python 3:

from io import StringIO
from html.parser import HTMLParser

class MLStripper(HTMLParser):
    def __init__(self):
        super().__init__()
        self.reset()
        self.strict = False
        self.convert_charrefs= True
        self.text = StringIO()
    def handle_data(self, d):
        self.text.write(d)
    def get_data(self):
        return self.text.getvalue()

def strip_tags(html):
    s = MLStripper()
    s.feed(html)
    return s.get_data()

Copy after login

For Python 2:

from HTMLParser import HTMLParser
from StringIO import StringIO

class MLStripper(HTMLParser):
    def __init__(self):
        self.reset()
        self.text = StringIO()
    def handle_data(self, d):
        self.text.write(d)
    def get_data(self):
        return self.text.getvalue()

def strip_tags(html):
    s = MLStripper()
    s.feed(html)
    return s.get_data()
