Click here to copy the following block
' get the text enclosed between two Delimiters
'
' it advances Index after the close delimiter
' Returns "" and Index = -1 if not found
' search is case sensitive
'
' For example:
'  Dim source As String = " a sentence with (a word) in parenthesis"
'  Dim i As Integer = 0
'  Console.WriteLine( GetDelimitedText(source, "(", ")", i) )
' displays "a word" and sets "i" pointing after the ")" char

Function GetDelimitedText(ByVal Text As String, ByVal OpenDelimiter As String, _
  ByVal CloseDelimiter As String, ByRef index As Integer) As String
  Dim i As Integer, j As Integer

  If index < 0 Then index = 0

  ' search the opening mark
  i = Text.IndexOf(OpenDelimiter, index)
  If i < 0 Then
    index = -1
    Exit Function
  End If
  i = i + OpenDelimiter.Length

  ' search the closing mark
  j = Text.IndexOf(CloseDelimiter, i)
  If j < 0 Then
    index = -1
    Exit Function
  End If

  ' get the text between the two Delimiters
  GetDelimitedText = Text.Substring(i, j - i)

  ' advance the index after the closing Delimiter
  index = j + CloseDelimiter.Length
End Function
