Thanks @phil-janeapp, this looks great 🙌

I was wondering if there was a way to fix the UNQUOTED_VALUE regexp so that it covers both double " and single ' quoted values.

Also it should add test coverage for single quoted ones

@elia I added a test for single-quoted attributes. Can you clarify what you meant about the UNQUOTED_VALUE check? In looking at the code there shouldn't be an issue with different quote styles.

Hey @phil-janeapp, sorry for letting you wait, I ended up checking out the branch to try the code out and implemented what I meant, feel free to check it out.

Thanks for tackling this! 🙌
