だから私は何をしますか..私は次のような正規表現に取り組んできました

^*(.?[\w\W?\s?]*)+(.com.au)$

しかし、それは役に立ちません..入力ファイルに必要なアドレス一致を指定すると、アドレスが一致します..しかし、一括で指定すると、役に立ちません。だから誰かが私を助けることができます..

正規表現に問題があります

^*(.?[\w\W?\s?]*)+(.com.au)$
 ^ ^           ^ ^ ^   ^
 1 1           2 2 1   1

  1. エスケープが必要な特別な文字

  2. 最後の「.com.au」までのすべてに一致する貪欲な数量詞、数量詞の後にを追加して、貪欲?でない==>一致をできるだけ少なくします（行末にある最初の「.com.au」までを意味します） ）。

    ==>これがあなたの主な問題です

  3. あなたは数量詞を入れ子*)+にします、あなたはそれを必要としません

  4. あなたの例では、「*」と「。」の間に空白があるので、空白に一致するか、ドットを完全に削除すると、文字クラスによって一致します。

  5. 行の先頭と「*」の間にも空白があります

だから、これを試してみてください

    ^\s*\*([\w\W?\s?]*?)(\.com\.au)$

ここRegexrでそれを参照してください

これを試して

^\s*\*\s*\[ \][^\*]+?[.]com[.]au$

説明

^        # Assert position at the beginning of a line (at beginning of the string or after a line break character)
\s       # Match a single character that is a “whitespace character” (spaces, tabs, and line breaks)
   *        # Between zero and unlimited times, as many times as possible, giving back as needed (greedy)
\*       # Match the character “*” literally
\s       # Match a single character that is a “whitespace character” (spaces, tabs, and line breaks)
   *        # Between zero and unlimited times, as many times as possible, giving back as needed (greedy)
\[       # Match the character “[” literally
\        # Match the character “ ” literally
\]       # Match the character “]” literally
[^\*]    # Match any character that is NOT a * character
   +?       # Between one and unlimited times, as few times as possible, expanding as needed (lazy)
[.]      # Match the character “.”
com      # Match the characters “com” literally
[.]      # Match the character “.”
au       # Match the characters “au” literally
$        # Assert position at the end of a line (at the end of the string or before a line break character)
