Fix discarding `html[lang]`

Jérémy BenoistandGitHub a18cd0f2a9 Merge pull request #102 from jtojnar/local-no-domain 
Do not set domainRegExp for local files
 2025-03-04 10:20:15 +01:00
Jan Tojnar efbbc86df9 Fix discarding html[lang] 
`DOMDocument::loadHTML` will parse HTML documents as ISO-8859-1 if there is no `meta[charset]` tag. This means that UTF-8-encoded HTML fragments such as those coming from JSON-LD `articleBody` field would be parsed with incorrect encoding.

In f14428e4c0, we tried to resolve it by putting `meta[charset]` tag at the start of the HTML fragment. Unfortunately, it turns out that causes parser to auto-insert a `html` element, losing the attributes of the original `html` tag.

Let’s try to insert the `meta[charset]` tag into the proper place in the HTML document.

We do not need to use the same trick with `JSLikeHTMLElement::__set`.
That expects smaller HTML fragments, not `html` documents, so creating `html` and `head` elements will not be a problem.

Jan Tojnar 541fab34a0 tests: Remove pointless debug assignment 
It is unused since 8ab7d76cd5.

Jan Tojnar 90869d877e tests: Use ::class for DOMDocument class name 
Also capitalize it properly.

Jan Tojnar c7208f6ad2 Do not set domainRegExp for local files 
`parse_url($this->url, \PHP_URL_HOST)` will return `null` for local filesystem path.
Casting it to `string` will produce an empty regular expression,
which would match any link when computing link density.
