Regex Hex Chars

Question

如何才能找到带正则表达式（0-9，a-f）和（m，n，o，k）的十六进制字符？

Answer 1

使用以下正则表达式：

[0-9a-fA-FmnokMNOK]

说明：

[                    #Match a single character present in the group (look below)
 0-9                 #All numbers from 0 to 9
    a-fA-F           #Characters from a to f (lowercase and uppercase)
          mnokMNOK   #The characters m, n, o and k (lowercase and uppercase)
                  ]  #End of character group
