试了好像不行，我用这个了 。改造他人的。

Public Function FilterHtml(ByVal content As String) As String

        Dim returnstr As String = ""

        Try
            Dim pattern As String = "<div[^>]*>(.*?)</div>"
            Dim reg As Regex = New Regex(pattern, RegexOptions.IgnoreCase Or RegexOptions.Compiled Or RegexOptions.Multiline)
            returnstr = reg.Replace(content, "")
        Catch ex As Exception

        End Try
        Return returnstr
    End Function
