各种名称的正则表达式

Question

我正在使用这个正则表达式来处理各种名称：

String Regex_Name="^([A-Za-z]*|\\p{L})+([ ]*|[A-Za-z]*|[']*|\\p{L}*)+([\\s]?[A-Za-z]*)+[A-Za-z]$";

运行代码时出现此错误：

Unknown character property name {​​​​​​​L} near index 44
^[A-Za-z][[A-Za-z]*\p{​​​​​​​L}​​​​​​​*[,]?[ ]?[-]?[A-Za-z]+]+([ ]?[.]?[,]?[(]?[A-Za-z]+[)]?[-]?\p{​​​​​​​L}​​​​​​​*)+([,]?|[.]?)$

我该如何解决这个问题？

Answer 1

使用

String Regex_Name="^\\p{L}+(?:[’'-]\\p{L}+)*(?:\\s+\\p{L}+(?:[’'-]\\p{L}+)*)*$";

见proof。

该表达式不支持缩短的缩写名称，例如 John G. Smith。
