Question

我想使用C＃中的正则表达式将[cite:lamport94]替换为\cite{lamport94}。

String input = "how easy it is to create a well structured document within [cite:lamport94].  You should quickly be able to see."

String output = "how easy it is to create a well structured document within \cite{lamport94}.  You should quickly be able to see."

Answer 1

以下是您可以使用的代码。它将使用“：”分隔符<：p>捕获方括号内的任何字母数字字符串

 var input = "how easy it is to create a well structured document within [cite:lamport94].  You should quickly be able to see.";
 var rxReg = new Regex(@"\[(\w+):(\w+)]");
 var result = rxReg.Replace(input, @"\$1{$2}");

输出：

how easy it is to create a well structured document within \cite{lamport94}.  You should quickly be able to see.

顺便说一句，如果括号内只有[a-zA-Z0-9_]个字符，则可以将\w扩展为[\w.:-]（我更喜欢匹配mm.xxx的模式，或{ {1}}或xx-yy字符串。如果需要，请添加更多字符串（请注意连字符必须保留在字符类的末尾以保留字面连字符。）

要仅限于xx:yyyy，请使用它而不是第一个cite：

\w

Answer 2

您可以使用以下内容进行匹配：

\[(cite):(.*?)\]    //assuming you always have cite as common

并替换为

\$1{$2}

使用正则表达式
