来自 Name 的 REGEX 特定单词

Question

我正在尝试找出格式错误的名称的正则表达式，例如用户输入的名称和关系作为一个值

[Son of Joseph Joestar ] => s/o. Joseph Joestar

问题是由于没有验证，用户输入了不同的变体，例如

s/o , s/, s/Joseph... 等

这是我到目前为止得到的

^(s\/o.)(S\/o.)(s\/o)(S\/o)(s\/)(S\/)\w+

relation是开头还是开头，后面是名字
还有3例女儿(D/o.),妻子(W/o.),父亲(F/o.)

想知道对应的REGEX来过滤关系前缀

提前致谢

Answer 1

也许从这样的事情开始

string foo = "s/o. Joseph Joestar";

// Look (and capture) for SDWF followed by "/" and 
// EITHER "o" and maybe "." and maybe a white space
// OR we look ahead (?=  ) and see a Upper wordchar followeed by lower word chars.
//   look ahead because we do not want to have anything to do with this when replacing
string bar = Regex.Replace(foo, @"^([sSdDwWfF])/(o\.?\s?|(?=[A-Z]\w+))", match =>
{
    string relation = match.Groups[1].Value.ToUpper() switch
    {
        "S" => "Son of",
        "D" => "Daughter of",
        "F" => "Father of",
        "W" => "Wife of",
        _ => throw new Exception("Oops")
    };
    return $"{relation} ";
});
