[TIPS] How to correct HTML tags

To correct messed-up HTML tags using Python, you can use libraries like BeautifulSoup from the bs4 module. BeautifulSoup is powerful for parsing and fixing HTML.

Here’s a step-by-step guide on how to use it:

 

Step 1: Install BeautifulSoup

If you haven’t installed BeautifulSoup and lxml (a parser library), you can install them using pip:

pip install beautifulsoup4 lxml

 

Step 2: Use BeautifulSoup to Parse and Correct HTML

Here’s an example script that reads an HTML string, parses it with BeautifulSoup, and then outputs the corrected HTML.

from bs4 import BeautifulSoup

# Example of messed-up HTML content
messed_up_html = """ YOUR MESSY HTML CONTENT """

# Parse the HTML
soup = BeautifulSoup(messed_up_html, 'lxml')

# Pretty print the corrected HTML
corrected_html = soup.prettify()
print(corrected_html)

Explanation

  • BeautifulSoup: A Python library for parsing HTML and XML documents. It creates a parse tree from page source code that can be used to extract data from HTML.
  • lxml: A parser for BeautifulSoup. It is faster and more lenient with broken HTML compared to the default parser.

 

Output

The prettify method formats the HTML nicely. The corrected HTML will look something like this:

clean html tags

 

Alternatives

There are some online services for you to validate the html tags and correct them:

  1. https://validator.w3.org/#validate_by_input
     
  2. https://www.freeformatter.com/html-validator.html
