Your VB.NET Code will be something like this.

Dim first, last As String
           
            first = "<p>"
            last = "</p>"
            Dim RE As New Regex(first + _
              "(?<MYDATA>.*?(?=" + last + "))", _
              RegexOptions.IgnoreCase Or RegexOptions.Singleline)
            

            Dim m As Match = RE.Match(yourData)
            ' got the result

            Dim output As String
            output = m.Groups("MYDATA").Value
