HTML is a markup language used to create web pages and is often used in web development. However, in some cases, we need to convert HTML to plain text, such as when sending emails or text messages. In order to avoid HTML tags interfering with reading, HTML needs to be converted to ordinary text. In this article, we will explore several ways to convert HTML to plain text.

BeautifulSoup library using Python

BeautifulSoup is a Python library for parsing HTML and XML documents. It converts HTML to plain text and can be easily customized. Here is a sample code that uses BeautifulSoup to convert HTML to plain text:

from bs4 import BeautifulSoup

html = '<html><body><p>This is some <strong>bold</strong> text.</p></body></html>'
soup = BeautifulSoup(html, 'html.parser')
text = soup.get_text()

print(text)

Copy after login

This code will output the following text:

This is some bold text.

Copy after login

Using Javascript's innerText attribute

If you are using Javascript on your web page, then you can use the innerText attribute to convert HTML to plain text. innerText is a property of an element that returns the text content of that element and all of its child elements, excluding markup. Here is a sample code that uses innerText to convert HTML to plain text:

var html = '<html><body><p>This is some <strong>bold</strong> text.</p></body></html>';
var element = document.createElement('div');
element.innerHTML = html;
var text = element.innerText;

console.log(text);

Copy after login

This code will output the following text:

This is some bold text.

Copy after login

Using regular expressions

Regular expressions are a powerful and flexible tool that can be used to extract specific content from text. If you don't want to use any library or framework, you can use regular expressions to convert HTML to plain text. Here is a sample code that uses regular expressions to convert HTML to plain text:

var html = '<html><body><p>This is some <strong>bold</strong> text.</p></body></html>';
var regex = /(<([^>]+)>)/ig;
var text = html.replace(regex, '');

console.log(text);

Copy after login

This code will output the following text:

This is some bold text.

Copy after login
