MSXML2.XMLHTTP响应不同于IE文档

Question

我想知道为什么在某些情况下，来自MSXML2.XMLHTTP对象的响应中的HTML不会产生与自动化Internet Explorer和检查document属性值相同的结果。

例如，下面的过程将使用对象MSXML2.XMLHTTP（列A）找到的结果与使用InternetExplorer对象（列B）找到的结果进行比较。

InternetExplorer对象的结果包括预期的纳斯达克指数，但MSXML2.XMLHTTP对象的结果不包括纳斯达克指数，并且完全不同：

Dim URL
Dim objHTML As HTMLDocument
Dim Oelement As Object
Dim ie As New InternetExplorer
Dim J, Field1, Field2

    Set objHTML = New HTMLDocument
    URL = "http://www.nasdaq.com/"

    '-------- METHOD1: MSXML2.XMLHTTP --------------------------
    With CreateObject("MSXML2.XMLHTTP")
    .Open "GET", URL, False
    .send
    objHTML.body.innerHTML = .responseText
    End With
    J = 0
    Set Field1 = objHTML.getElementsByTagName("td")
    For Each Oelement In Field1
    Worksheets("sheet1").Cells(J + 1, 1) = Field1(J).innerText
    J = J + 1
    Next Oelement

    '----------METHOD2: InternetExplorer Object----------------
    Set ie = New InternetExplorer
    With ie
    .navigate URL
    .Visible = False
    While .Busy Or .readyState <> READYSTATE_COMPLETE
    DoEvents
    Wend
    Set objHTML = .document
    DoEvents
    End With
    J = 0
    Set Field1 = objHTML.getElementsByTagName("td")
    For Each Oelement In Field1
    Worksheets("sheet1").Cells(J + 1, 2) = Field1(J).innerText
    J = J + 1
    Next Oelement
    DoEvents
    ie.Quit
    DoEvents
    Set ie = Nothing
    '----------------------------------------------
    End Sub
