是的，您使用MXSML发出http请求。这是一个示例，并对您现有的代码进行了一些重构

Sub Main()

    Dim vaWrite As Variant
    Dim hDoc As MSHTML.HTMLDocument
    Dim xHttp As MSXML2.XMLHTTP

    'Set a reference to MSXML2
    'Open a webpage using GET
    Set xHttp = New MSXML2.XMLHTTP
    xHttp.Open "GET", "http://stackoverflow.com/questions/15103048/count-data-on-webpage-from-url-in-excel-vba"
    xHttp.send

    'Wait for the web page to finish loading
    Do Until xHttp.readyState = 4
        DoEvents
    Loop

    'If the web page rendered properly
    If xHttp.Status = 200 Then
        'Create a new HTMLdocument
        Set hDoc = New MSHTML.HTMLDocument
        'Put the GET response into the doc's body
        hDoc.body.innerHTML = xHttp.responseText

        'Get an array back containing the readability scores
        vaWrite = Display_Stylometric_Scores(hDoc.body.innerText)

        'Write that array to a worksheet
        Sheet1.Range("A2").Resize(UBound(vaWrite, 1), UBound(vaWrite, 2)).Value = vaWrite
    End If

End Sub

Function Display_Stylometric_Scores(ByRef sText As String) As Variant

    Dim aReadStats(1 To 1, 1 To 12) As Double
    Dim wdDoc As Object
    Dim wdRs As Object
    Dim i As Long
    Dim vaSpecial As Variant

    Const lMAXIDX As Long = 10

    vaSpecial = Array("&", "!")

    Set wdDoc = CreateObject("Word.Document")
    wdDoc.Content = sText

    Set wdRs = wdDoc.Content.ReadabilityStatistics

    For i = 1 To lMAXIDX
        aReadStats(1, i) = wdRs(i).Value
    Next i

    For i = LBound(vaSpecial) To UBound(vaSpecial)
        aReadStats(1, lMAXIDX + 1 + i) = CountChar(sText, vaSpecial(i))
    Next i

    Display_Stylometric_Scores = aReadStats

End Function

Function CountChar(ByRef sText As String, ByVal sChar As String) As Long
    CountChar = Len(sText) - Len(Replace(sText, sChar, vbNullString))
End Function
