Split string with Regex

[Ronald de Boer]

Hi, I need to split a large string and split that splitted string again. I have the following string:

root
{
stringB =
{
"key": "value",
"key": "value",
"StringC":
{
"key": "value",
"key": "value",
"key": "value",
"key": "value",
}
"StringD": "value",
"StringE":
{
"key": "value",
}
}
}

The result I actually want is something like this: string[] AllStrings = StringB,StringC,StringD,StringE Is there a way to do this? I used Regex.Split option. Thanks in advance!

That doesn't look regular enough. And try the Regex forum.

You could probably do it with String.Split()[^].

I believe you are trying to parse a JSON string. If yes then this link might be of some help to you!

You can parse using JavaScriptSerializer.. This may help to you

string s = "{\"StringC\":"+
"{"+
"\"key1\": \"value\"," +
"\"key2\": \"value\"," +
"\"key3\": \"value\"," +
"\"key4\": \"value\"" +
"},"+
"\"StringD\": \"value\"," +
"\"StringE\":" +
"{"+
"\"key1\": \"value\"" +
"}"+
"}";

        JavaScriptSerializer f =new JavaScriptSerializer();

        JsonData jsd = f.Deserialize<JsonData>(s);

public class JsonData
{
public Hashtable StringC { get; set; }
public string StringD {get; set;}
public Hashtable StringE { get; set; }
}

Just so you know, your sample string isn't very consistent. I would think there would have to be a comma after the closing braces. Beyond that, it seems to me you want to Split on the "{" character, and then the "," character on each of the first split result strings. I would probably write a method that accepted the delimiter character and the string to be split that returned an array of split items. Regex is not what you want to use - sometimes, you just gotta write the code.

Try

(.*((\"([\d\w]+)\":)|(\s([\d\w]+) =)))*

The group no 4 contains keys like key or stringC and group 6 contins keys like StringB EDIT: Of course you need to code

string expr = @"(.*((\"([\d\w]+)\":)|(\s([\d\w]+) =)))*";
var m = Regex.Match(expr);
var group4 = m.Groups[4];
var group6 = m.Group[6];
string[] allStrings = group4.Captures.Select(c=>c.Value).Union(group6.Select(c=>c.Value)).ToArray();

captures now contains strings you need DISCLAIMER: 1. not tested. 2. use named groups if you want to.
