I have a string which is in the following format:
[0:2]={1.1,1,5.1.2}
My requirement here is to split the values inside curly braces after = operator, and store them in to a string array. I had tried to split part by using Substring() and IndexOf() methods, and it worked. But I needed a cleaner and elegant way to achieve this via regular expressions.
Does anybody having clues to achieve my requirement?
Here is your fully RegEx solution:
Dim input As String = "[0:2]={1.1,1,5.1.2}"
Dim match = Regex.Match(input, "\[\d:\d\]={(?:([^,]+),)*([^,]+)}")
Dim results = match.Groups(1).Captures.Cast(Of Capture).Select(Function(c) c.Value).Concat(match.Groups(2).Captures.Cast(Of Capture).Select(Function(c) c.Value)).ToArray()
Don't think it is more readable then standard split:
Dim startIndex = input.IndexOf("{"c) + 1
Dim length = input.Length - startIndex - 1
Dim results = input.Substring(startIndex, length).Split(",")
You could use a regular expression to extract the values inside the curly braces, and then use an ordinary Split:
Regex.Match("[0:2]={1.1,1,5.1.2}", "{(.*)}").Groups(1).Value.Split(","c)
Dim s As String = "[0:2]={1.1,1,5.1.2}";
Dim separatorChar as char = "="c;
Dim commaChar as char = ","c;
Dim openBraceChar as char = "{"c;
Dim closeBraceChar as char = "}"c;
Dim result() as String =
s.Split(separatorChar)(1)
.trim(openBraceChar)
.trim(closeBraceChar)
.split(commaChar);
(assuming it works! Typed on an iPad so can't verify syntax easily, but principal should be sound).
EDIT: updated to VB as downvoted for showing working .net methods in c# syntax.
if you want it using Regex
Dim s() As String=Regex.match(str,"(={)(.*)(})").Groups(1).Tostring.split(',');
[0:2]={and the trailing}.
