Attribute value in form tag becaome lowcase

[gyuber]

Hello~

special attribute are lowcased
example)
https://go.dev/play/p/5Ntxc6sP35r

func main() {
	m := minify.New()
	m.Add("text/html", &html.Minifier{
		KeepQuotes:   true,
		KeepEndTags:  true,
		KeepComments: true,
	})

	m.AddFuncRegexp(regexp.MustCompile("^(application|text)/(x-)?(java|ecma)script$"), js.Minify)

	tag := `<form target="TarGet" method="Method">`
	s, err := m.String("text/html", tag)
	if err != nil {
		panic(err)
	}
	fmt.Println(s)
}

<form target="target" method="method">

expect

<form target="TarGet" method="Method">

Can you help me?

Hi, the attribute value is case-insensitive. It shouldn't matter if it's lowercase. The minifier uses lowercase to improve the optimization by GZIP (after minification).

What is the problem you're having? Is this related to JS?

I know that attribute name is case-insensitive.
but value is no mention

Well, the HTML minifier doesn't lowercase values in general, but a specific set of attribute are lowercased according to this list: https://html.spec.whatwg.org/multipage/indices.html#attributes-3

Specifically, method can be any of get,post,dialog (case-insensitive) and target must be a valid navigable name which can be a framename (case-sensitive). I've fixed tha latter case.

Agree .. method can be case-insensitive..
Can I Check to attrmap case-insensitive or case-sensitive ?

I've disabled attribute value lowercasing, it is causing too many problems for various users.
