C# Regex: Wie zum extrahieren von Zeichenfolgen in Anführungszeichen

Versuchen Sie Folgendes:

using System.Text.RegularExpressions;

public static MatchCollection getMatches(String input, String pattern) {
   Regex re = new Regex(pattern);
   return re.Matches(input);
}

public static void Example() {
   String pattern1 = "var matches = new Array\\(([^\\)]+)\\)";

   MatchCollection results = getMatches(RandomTest, pattern1);
   String marray = results[0].Groups[1].Value;

   String pattern2 = "\"([^\"]+)\"";
   List<String> values = new List<String>();
   foreach (Match value in getMatches(marray,pattern2)) {
      //Your values are in the Groups property
      values.Add(value.Groups[1].Value);
      Console.WriteLine(value.Groups[1].Value);
   }
}

Das erste Muster extrahiert die matches-array und die zweite packt alle angegebenen Werte im array

Ich glaube, Sie müssen entfernen, die " am Anfang und am Ende und split durch
","

string [] test=Regex.Split(s.SubString(1,s.length-2), "\",\"");

Wenn Sie eine einzige Liste für alle Linien zusammen verwenden:

///<returns>Returns all values inside matches array in a single list</returns>
        public static List<string> GetMatchesArray(String inputString)
        {
            //Matches var matches = new Array( ... );
            Regex r = new Regex("(var matches = new Array\\([^\\)]*\\);)",
                RegexOptions.IgnoreCase | RegexOptions.Compiled | RegexOptions.Multiline);

            string arrayString = r.Match(inputString).Groups[0].Value;

            List<string> quotedList = new List<string>();

            //Matches all the data between the quotes inside var matches
            r = new Regex("\"([^\"]+)\"", RegexOptions.IgnoreCase | RegexOptions.Compiled | RegexOptions.Multiline);
            for (Match m = r.Match(arrayString); m.Success; m = m.NextMatch())
            {
                quotedList.Add(m.Groups[1].Value);
            }

            return quotedList;
        }

Wenn Sie möchten, um eine separate Liste pro Zeile haben, sollten Sie eine Liste von Zeilen, und in jeder Liste sollten Sie über eine Liste von zitierten text. Der folgende code tun:

///This will help you store the data in a list in a more meaningful way, 
///so that you are able to organize the data per line
///Returns all the quoted text per line in a list of lines
public static List<List<string>> GetMatchesArrayPerLine(String inputString)
{
    //Matches var matches = new Array( ... )
    Regex r = new Regex("(var matches = new Array\\([^\\)]*\\);)",
        RegexOptions.IgnoreCase | RegexOptions.Compiled | RegexOptions.Multiline);

    string arrayString = r.Match(inputString).Groups[0].Value;

    List<string> lineList = new List<string>();

    //Matches all the lines and stores them in lineList one line per item. For e.g.
    //"125","1.FC Nurnberg - TSV 1860 Munich", ...
    //"126","FC Ingolstadt 04 - TuS Koblenz", ...
    r = new Regex("\n(.*)", RegexOptions.IgnoreCase | RegexOptions.Compiled | RegexOptions.Multiline);
    for (Match m = r.Match(arrayString); m.Success; m = m.NextMatch())
    {
        lineList.Add(m.Groups[1].Value);
    }

    List<List<string>> quotedListPerLine = new List<List<string>>();

    //Matches the quoted text per line. 
    //This will help you store data in an organised way rather than just a list of values
    //Similar to a 2D array
    //quotedListPerLine[0] = List<string> containing { "125", "1.FC Nurnberg - TSV 1860 Munich", ... }
    //quotedListPerLine[1] = List<string> containing { "126","FC Ingolstadt 04 - TuS Koblenz", ... }
    r = new Regex("\"([^\"]+)\"", RegexOptions.IgnoreCase | RegexOptions.Compiled);
    foreach (string line in lineList)
    {
        List<string> quotedList = new List<string>();
        for (Match m = r.Match(line); m.Success; m = m.NextMatch())
        {
            quotedList.Add(m.Groups[1].Value);
        }
        quotedListPerLine.Add(quotedList);
    }

    return quotedListPerLine;
}

List<List<string>> quotedListLines = MyRegEx.GetMatchesArrayPerLine(a);
foreach (List<string> line in quotedListLines)
{
    Console.WriteLine("----LINE---");
    foreach (string quotedText in line)
        Console.WriteLine(quotedText);
}
