How to get the selectors of all classes from the style sheet?

Question

css

Good afternoon. There is a huge style sheet. How can I get only selectors from this table, without the css rules themselves? Initially has SCSS syntax. I have not worked with PostCSS before, but maybe it will help in solving this problem?

Answer 1

Copy the code of the table and clean the attributes in the editor with regular expressions.
For example, we are looking for all the STYLE attributes and replacing them with emptiness.
style="[^"]*
