移除自定義標記標記所需的正則表達式

我之前沒有寫過正則表達式，而且我的知識遠遠不足。我希望這裏的專家能夠幫助我使用C＃中的正則表達式來刪除標記標籤。移除自定義標記標記所需的正則表達式

的標記具有一個下面開口標籤：<AI>!或<AH>!或<AG>!，並與另一!

實施例結束：the quick brown <AI>!fox jumps! over the lazy dog!

標記除去應後：the quick brown fox jumps over the lazy dog!

代碼段：

使用將尋找在<>一個隨後的一個[GHI]包圍的正則表達式！。它發現後，它會做一個懶搜索（由表示？）一個或多個（+）什麼（。），然後是一個感嘆號的。這是懶惰的，所以它不會尋找，直到它找到樣本中的最後一個感嘆號，它會停在第一個感嘆號並替換它找到的。然後它將使用分組（格式中的括號）來存儲標籤中包含的值，並在替換時使用它（$ 1表示第一組）。

var r = new Regex("<A[GHI]>!(.+?)!"); 
var actual = r.Replace(xml, "$1");

打破正則表達式，並解釋到OP和其他人將是一個很好的事情。 – Oded 2012-04-03 14:52:45

好呼！這足夠嗎？ – 2012-04-03 14:57:48

完美謝謝你 – Shurugwi 2012-04-03 15:21:28

使用必須是這樣的正則表達式：

\<..\>!([^!]*)!

，因爲你必須< 兩個字母>匹配！ 一系列的人物沒有！最後一個！再次。

然後，您通過捕獲的匹配（即括號之間的文本）替換匹配（與上述表達式匹配的整個文本）。

} 

Original String: '<AI>!n!-Butyl acetate the quick brown <AI>!fox jumps! over the lazy dog!' 
Replacement String: 'n-Butyl acetate the quick brown fox jumps over the lazy dog!'
