那我该怎么做..
我一直在处理像

的正则表达式

^ *（。？[\w\W？\s？] *）+（。com.au）$

但那不是帮助..它匹配的地址，当我给与我想要的地址匹配的输入文件..但是当批量给出时，它没有帮助。
，所以有人可以帮我解决问题。

解决方案

试试这个

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

解释

  ^＃在行首（位于字符串的开头或换行符后）的断言位置
 \s＃匹配单个字符是一个空白字符（空格，制表符和换行符）
 *＃在零和无限次之间，尽可能多地根据需要返回（贪婪）
 \ *＃字面上匹配字符*
 \s＃匹配一个空白字符（空格，制表符和换行符）的单个字符
 *＃在零和无限次之间，多次（贪婪）
 \ [[＃字符串匹配
 \＃匹配字符字面意思
 \]＃匹配字符]字面意思
 [^ \ *]＃匹配任何不是字符
 +的字符？ ＃在一次和无限次之间，尽可能少的次数，根据需要扩展（懒惰）
 [。]＃匹配字符。
 com＃字符串匹配字符com
 [。]＃匹配字符。
 au＃将字符au逐字匹配
 $＃在行末尾（位于字符串末尾或换行符前） ）

so what do i do.. i've been working on regular expressions like

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

but thats not helping.. it matches the address when i give the input file with the address match i want.. but when given in bulk, it doesnt help. so can somebody help me out..

解决方案

Try this

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

explanation

^        # 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)
