How Can I Efficiently Strip HTML Tags from Strings in Python?

Stripping HTML from Strings in Python

When interacting with HTML content, it often becomes necessary to separate the meaningful text from the markup tags for further processing or analysis. Here's how to achieve this efficiently in Python.

To strip HTML tags from a string, utilize the HTMLParser from the Python standard library. This parser provides a straightforward way to parse HTML documents and extract only the desired content.

For Python 3, employ the following code:

from io import StringIO
from html.parser import HTMLParser

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

def strip_html(html):
    stripper = TagStripper()
    stripper.feed(html)
    return stripper.get_data()

For Python 2, use the following code:

from HTMLParser import HTMLParser
from StringIO import StringIO

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

def strip_html(html):
    stripper = TagStripper()
    stripper.feed(html)
    return stripper.get_data()

Now, let's illustrate its usage:

html = "<p>Hello, <em>world</em>!</p>"
stripped_text = strip_html(html)
print(stripped_text)  # Output: Hello, world!
