Python regex look-behind requires fixed-width pattern

Question

When trying to extract the title of a html-page I have always used the following regex:

(?<=)([\\s\\S]*)(?=)

<

Answer 1

Toss out the idea of parsing HTML with regular expressions and use an actual HTML parsing library instead. After a quick search I found this one. It's a much safer way to extract information from an HTML file.

Remember, HTML is not a regular language so regular expressions are fundamentally the wrong tool for extracting information from it.
