Regex VB.Net Regex.Replace

Question

I\'m trying to perform a simple regex find and replace, adding a tab into the string after some digits as outlined below.

From

a/users/12345/badges
         


        

Answer 1

When I read, "adding a tab into the string after some digits" I think there could be more than one set of digits that can appear between forward slashes. This pattern:

"/(\d+)/"

Will capture only digits that are between forward slashes and will allow you to insert a tab like so:

Imports System.Text.RegularExpressions

Module Module1
    Sub Main()
        Dim str As String = "a/54321/us123ers/12345/badges"
        str = Regex.Replace(str, "/(\d+)/", String.Format("/$1{0}/", vbTab))

        Console.WriteLine(str)
        Console.ReadLine()
    End Sub
End Module

Results (NOTE: The tab spaces can vary in length):

a/54321 /us123ers/12345 /badges

When String is "a/54321/users/12345/badges" results are:

a/54321 /users/12345    /badges
