How to remove HTML comments using Regex in Python

Question

I want to remove HTML comments from an html text

<h1>heading</h1> <!-- comment-with-hyphen --> some text <-- con --> more text <hello></hello> more text

should result in:

<h1>heading</h1> some text <-- con --> more text <hello></hello> more text

Answer 1

Finally came up with this option:

re.sub("(<!--.*?-->)", "", t)

Adding the ? makes the search non-greedy and does not combine multiple comment tags.

Answer 2

You shouldn't ignore Carriage return.

re.sub("(<!--.*?-->)", "", s, flags=re.DOTALL)
