What you need to do is to find the start and stop position of the string you want and copy it out. There are many different functions you can use to accomplish this but it basically use the same concept.

Dim StartPos, StopPOS As Integer
Dim TempStr As String = "<mytag>VB City</mytag>"
Dim ResultStr As String
StartPos = TempStr.IndexOf("<mytag>") + 7 'add the offset of the tag
StopPOS = TempStr.IndexOf("</mytag>")
ResultStr = TempStr.Substring(StartPos, StopPOS - StartPos)

You might want to look up on the following functions: InStr, InStrRev, Mid, IndexOf, SubString, Insert, Remove, Replace...
