有一点是网页上的样品code，但我已经添加了一些额外的这里，将返回正是你想要的。

There is a bit of sample code on that page but I've added a bit extra here that will return exactly what you want

Imports System.Xml
Imports System.IO
Imports System.Net
Imports System.Text

Function FromHtml(ByVal reader As TextReader) As XmlDocument
    '' setup SgmlReader   
    Dim sgmlReader As Sgml.SgmlReader = New Sgml.SgmlReader()
    sgmlReader.DocType = "HTML"
    sgmlReader.WhitespaceHandling = WhitespaceHandling.None
    sgmlReader.CaseFolding = Sgml.CaseFolding.ToLower
    sgmlReader.InputStream = reader
    '' create document 
    Dim doc As XmlDocument = New XmlDocument()
    doc.PreserveWhitespace = True
    doc.XmlResolver = Nothing
    doc.Load(sgmlReader)
    Return doc
End Function

Function LoadWebText(ByVal URL As String) As String
    Dim objWebClient As New WebClient()
    Dim objUTF8 As New UTF8Encoding()

    Dim xml As New XmlDocument
    xml = FromHtml(New StringReader(objUTF8.GetString(objWebClient.DownloadData(URL))))

    Return xml.InnerText()

End Function
