c# - 查找特定子字符串中匹配的乘法组

Question

我想捕获下面字符串中以“need”字开头的粗体值，而其他字符串中以“skip”和“ignored”开头的字必须被忽略。我尝试了模式

需要.+?(:"(?'index'\w+)"[,}])

但它只找到第一个(重点)值。如何仅使用 RegEx 获得所需的结果？

“跳过”:{“A”:“ABCD123”，“B”:“ABCD1234”，“C”:“ABCD1235”

"需要":{"A":"ZABCD123","B":"ZABCD1234","C":"ZABCD1235”

“忽略”:{“A”:“SABCD123”，“B”:“SABCD1234”，“C”:“SABCD1235”}

Answer 1

我们要找到需要并将找到的内容分组到Named Match Group中=> Captures .将有两组，一组名为 Index，其中包含 A |乙 | C 然后是一个名为 Data 的文件。

比赛将保存我们的数据，如下所示:

从那里我们将它们加入字典:

下面是实现这个魔法的代码:

string data =
@"""skip"" : {""A"":""ABCD123"",""B"":""ABCD1234"",""C"":""ABCD1235""}
""need"" : {""A"":""ZABCD123"",""B"":""ZABCD1234"",""C"":""ZABCD1235""}
""ignore"" : {""A"":""SABCD123"",""B"":""SABCD1234"",""C"":""SABCD1235""}";

string pattern = @"
\x22need\x22\s *:\s *{   # Find need
(                        # Beginning of Captures
   \x22                     #  Quote is \x22
   (?<Index>[^\x22] +)      # A into index.
   \x22\:\x22               # ':'
   (?<Data>[^\x22] +)       # 'Z...' Data
   \x22,?                   # ',(maybe)
)+                       # End of 1 to many Captures";


var mt = Regex.Match(data, 
                     pattern, 
                     RegexOptions.IgnorePatternWhitespace | RegexOptions.ExplicitCapture);

// Get the data capture into a List<string>.
var captureData = mt.Groups["Data"].Captures.OfType<Capture>()
                                            .Select(c => c.Value).ToList();

// Join the index capture data and project it into a dictionary.
var asDictionary = mt.Groups["Index"]
                     .Captures.OfType<Capture>()
                     .Select((cp, iIndex) => new KeyValuePair<string,string>
                                                 (cp.Value, captureData[iIndex]) )
                     .ToDictionary(kvp => kvp.Key, kvp => kvp.Value );
