Read txt file between symbols

I am working on a program, and need a way to store data. So I was thinking of making a text file like so.

name:david:lastname: offerman:

So I need it to read in between name: and :

Or if someone could walk me through how to read XML that would be great and better.

i'd use a text file + regex:

vb Code:

Dim testStr As String = "name:david:lastname:offerman:"
Dim rx As New Regex("(?<=name\:).+?(?=\:)")
        
For Each m As Match In rx.Matches(testStr)
    MsgBox(m.Value)
Next

don't forget to import regex:

vb Code:

Imports System.Text.RegularExpressions

Thank you SO much. This did the trick, but I should of thought better about lastname since it comes up, But I changed it to last so its all good. Thanks.
