[199] zcorpan/html-parser-book: Idiosyncracies of the HTML parser (2020-12-18T03:16:52.000Z) https://github.com/zcorpan/html-parser-book/

[200] HTML を取り扱う | ちいさな Web ブラウザを作ってみよう, 2021-08-09T23:21:30.000Z, 2023-08-01T06:21:40.553Z https://browserbook.shift-js.info/chapters/parsing-html

他の多くのプログラミング言語と異なり、HTML の取り扱いがやっかいな理由の一つに、HTML Standard は HTML の字句規則や構文規則が正規表現や BNF のような形で記述されていないという事実が挙げられます。本来、正規表現や BNF のような形で HTML の字句規則や構文規則が定義されているのであれば、HTML の取り扱いには、一般的なコンパイラ作成のときの考え方をそのまま適用できるはずなのにです。とりわけ世の中には flex や bison といった字句解析器・構文解析器を生成するためのツールも存在しますから、この場合、実装難易度は大きく下がるはずです。
いま、HTML の構文が BNF のような形で記述されていない背景には、多少マークアップが雑でも Web ページの利用に支障が出ないように、HTML が非常にゆるい文法を採用していることが挙げられます。

[201] >>200 この説明は誤り。 HTML が BNF を使わないのは、 BNF では HTML構文解析器を正確に記述できないから。「生成規則を flex や bison に食わせれば構文解析器は簡単に作れる」というまさにその考え方 (によってもたらされる相互運用性の低下) への反省が今の HTML Standard を形作っている。

[202] HTML Standard が BNF を使っていないのは、「ゆるい文法」が BNF で記述できないからではない。実際、 HTML Standard の (構文解析器ではなく) HTML構文の章は、英語で書かれているが、 BNF にほぼ逐語訳できる。文法を BNF で書けるかどうかと構文解析器の挙動は別の問題で、それぞれちゃんと記述したのが HTML5 の成果。

HTML要素概説

注釈

HTML5構文解析器HTML5 parser HTML5 の規定に従った構文解析器。 HTML5 の構文解析器は Internet Explorer をはじめとするそれ以前の主要なWebブラウザーの挙動を解析して規定されたものだったが、当時は実装ごとの違いも多かった。主要なWebブラウザーは HTML5 の規定に従い構文解析器を全面改修したため、従来の構文解析器と区別してHTML5構文解析器という。現在ではすべてがHTML5構文解析器である (ただし HTML5 以後の仕様変更を含む)。
