Error when selecting something with this syntax div.My(1) #84

I wanted to scrape something from yahoo website and there are classes in the html like this My(8) P(w) ... and I'm getting an error using it.

thread 'scrape::scraper::tests::parse_titles_test' panicked at 'called `Result::unwrap()` on an `Err` value: ParseError { kind: Custom(ClassNeedsIdent(Function("My"))), location: SourceLocation { line: 0, column: 4 } }', src/scrape/scraper.rs:51:54

    scrape::scraper::tests::parse_titles_test

test result: FAILED. 0 passed; 1 failed; 0 ignored; 0 measured; 0 filtered out; finished in 0.97s

How can I fix this?

You can't use '(' as part of a css identifier: https://www.w3.org/TR/css-syntax-3/#typedef-ident-token. However, you can escape it using a backslash, so div.My(1) would become div.My\(1\).

Thank you. I managed to scrape it without these classes, think your solution works.
