首先介紹一下正則表示式的基本語法，不使用任何一門語言，就使用notepad++進行正則表示式的操作。

• 正則表示式：正則表示式表達就是操作字串的一個規則，正則表示式使用了特殊的符號表示。

• 正則表示式對字串的操作主要有一下集中應用：

  1. 匹配
  2. 切割
  3. 替換
  4. 查詢

• 預定義字元(注意：任何預定義字元沒有加上數量詞之前都只能匹配一個字元，比如"12"就不能被”\\d“匹配)：

  1. . 表示任何字元（與行結束符可能匹配也可能不匹配）
  2. \d 數字：[0-9]
  3. \D 非數字字元：[^0-9]
  4. \s 空白字元：[\t\n\xoB\f\r]
  5. \S 非空白字元：[^\s]
  6. \w 單詞字元：[a-zA-Z_0-9]就是包括a-z,A-Z,0-9,下劃線。

• 數量詞：

  1. X? X，一次或一次也沒有
  2. X* X,零次或多次
  3. X+ X,一次或者多次
  4. X{n} X,恰好n次
  5. X{n,} X,至少n次
  6. X{n,m} X,至少n次，但是不超過m次

• 範圍詞（只能匹配一個字元）：

  1. [abc] a,b或者c
  2. [^abc] 任何字元，除了a,b或c
  3. [a-zA-Z] a到z或A-Z，兩頭的字母包括在內（範圍）
  4. [a-dm-p] a到d或者m到p
  5. 注意：範圍詞裡不管內容有多長，沒有數量詞的配合都只能匹配一個字元而已。
• 正則表示式之分組匹配及反向引用
  
  1. 如果正則的內容需要被複用，那麼需要對正則的內容進行分組。分組的目的就是為了提高正則的複用性。組號不能自己指定，組號從1開始。
  2. 分組巢狀關係說明：((A)(B(C))):一共四組，1號組是((A)(B(C)))，2號組是(A),3號組為(B(C)),4號組(C).\1:引用第一組所匹配到的內容。這樣的話巢狀關係就很容易看見了。
  3. \1或$1　　用於匹配第一個分組中的內容
     \2或$2　　用於匹配第一個分組中的內容
     …
     \9或$9　　用於匹配第一個分組中的內容
  4. 一般情況下我們匹配任意兩個相同的字元就可以用\1或者$1等來引用比如字串"AA Am 99"，現在要匹配出重複的字元，用這個(\w)\1正則表示式就可以，匹配結果："AA", "99"
  5. 說明：(\w)用來匹配任何除了換行和製表符的字元, 而\1是對(\w)的一個引用, 所以你可以理解成: (\w)\1
     就是(\w)(\w)但是,(\w)\1 和 (\w)(\w)的不同之處在於, (\w)(\w)表示任意兩個連續的字元, 比如Ac, MM, K9, 都可以,但(\w)\1只能是AA, CC, 99 這樣連續相同的字元所以, 你可以這樣理解, \1 是對(\w)的一個例項化引用, 當(\w) 匹配到A時, \1 被表達成A, 當(\w)匹配9時, \1 被表示成9。
• 現在用notepad++的正則表示式查詢內容並把內容加上引號。
  
  1. 現在給出資料：
