HTML テーブルがどのように機能するかはよく知っていますが、ソースコードの構文がわかりません。CSS だと思いますが、自動化された方法でこのテーブルを Excel または CSV 形式に変換する方法についてはまだ問題が残っています。

どんな助けでも大歓迎です。

ありがとう

これはテーブルではなく、単なるスパン要素です。HTML/CSS をある種のプログラミング言語と混同していると思います。CSSでスクレイピングすることはできません。そのためには、PHP などのプログラミング言語を使用する必要があります。

PHP 関数file_get_contents http://php.net/manual/en/function.file-get-contents.phpを見てください。それを使用して、スクレイピングするページの完全なアドレスを渡します。この関数はソースコード全体を返します。そこから、データのマッサージを開始し、できれば探しているものを取得できます。

返された文字列を取得し、RegEx を使用して分解し、ソースコード内のパターンを探して、抽出しようとしている部分を返します。

または、ウェブサイトの所有者にデータのコピーを依頼するだけです。私は彼らが素晴らしいExcelファイルにそれを持っていると確信しています;-)

html - CSS を使用して Web サイト (提供されるリンク) からテーブルをスクレイピングするにはどうすればよいですか?
