html - 使用 VBA 解析 HTML 内容

Question

目前，我正在努力解析 data.cnbc.com/quotes/sdrl 中的报价表，并将 innerhtml 放入我指定的股票代码旁边的列中。

因此，我会从 A2 中获取符号，然后将 yield 数据放入 C2，然后移至下一个符号。

HTML 看起来像:

<table id="fundamentalsTableOne">
  <tbody>
    <tr scope="row">
        <th scope="row">EPS</th>
        <td>8.06</td>
    </tr>
    <tr scope="row">
        <th scope="row">Market Cap</th>
        <td>5.3B</td>
    </tr>
    <tr scope="row">
        <th scope="row">Shares Out</th>
        <td>492.8M</td>
    </tr>
    <tr scope="row">
        <th scope="row">Price/Earnings</th>
        <td>1.3x</td>
    </tr>
</tbody>
</table>
<table id="fundamentalsTableTwo">
  <tbody>
    <tr scope="row">
        <th scope="row">Revenue (TTM)</th>
        <td>5.0B</td>   
    </tr>
    <tr scope="row">
        <th scope="row">Beta</th>
        <td>1.84</td>
    </tr>
    <tr scope="row">
        <th scope="row">Dividend</th>
        <td>--</td>
    </tr>
    <tr scope="row">
        <th scope="row">Yield</th>
        <td><span class="pos">0.00%</span></td>
    </tr>
  </tbody>
</table>

目前，我有:

Sub getInfoWeb()

Dim cell As Integer
Dim xhr As MSXML2.XMLHTTP60
Dim doc As MSHTML.HTMLDocument
Dim table As MSHTML.HTMLTable
Dim tableCells As MSHTML.IHTMLElementCollection

Set xhr = New MSXML2.XMLHTTP60

For cell = 2 To 5

ticker = Cells(cell, 1).Value

    With xhr

        .Open "GET", "http://data.cnbc.com/quotes/" & ticker, False
        .send

        If .readyState = 4 And .Status = 200 Then
            Set doc = New MSHTML.HTMLDocument
            doc.body.innerHTML = .responseText
        Else
            MsgBox "Error" & vbNewLine & "Ready state: " & .readyState & _
            vbNewLine & "HTTP request status: " & .Status
        End If

    End With

    Set table = doc.getElementById("fundamentalsTableOne")
    Set tableCells = table.getElementsByTagName("td")

    For Each tableCell In tableCells

            Cells(cell, 2).Value = tableCell.NextSibling.innerHTML

    Next tableCell

Next cell

End Sub

但是，我收到“访问被拒绝”错误，并且在我的 set tablecells 行中收到运行时 91。这是因为每一行只有一个元素并且表格单元格被设置为一个集合吗？另外，“访问被拒绝”错误是由于 javascript 生成的 HTML 造成的吗？我认为这不会成为问题。

如果有人知道如何使其正常工作，我们将不胜感激。谢谢。

以下示例展示了如何获取所需的数据:

GetData "sdrl"

Sub GetData(sSymbol)
    Dim sRespText, arrName, oDict, sResult, sItem
    XmlHttpRequest "GET", "http://data.cnbc.com/quotes/" & sSymbol, "", "", "", sRespText
    ParseToNestedArr "<span data-field=""name"">([\s\S]*?)</span>", sRespText, arrName
    XmlHttpRequest "GET", "http://apps.cnbc.com/company/quote/newindex.asp?symbol=" & sSymbol, "", "", "", sRespText
    ParseToDict "<tr[\s\S]*?><th[\s\S]*?>([\s\S]*?)</th><td>(?:<span[\s\S]*?>)*([\s\S]*?)(?:</span>)*</td></tr>", sRespText, oDict
    sResult = arrName(0)(0) & vbCrLf & vbCrLf
    For Each sItem in oDict.Keys
        sResult = sResult & sItem & " = " & oDict(sItem) & vbCrLf
    Next
    MsgBox sResult
End Sub

Sub ParseToDict(sPattern, sResponse, oList)
    Dim oMatch, arrSMatches
    Set oList = CreateObject("Scripting.Dictionary")
    With CreateObject("VBScript.RegExp")
        .Global = True
        .MultiLine = True
        .IgnoreCase = True
        .Pattern = sPattern
        For Each oMatch In .Execute(sResponse)
            oList(oMatch.SubMatches(0)) = oMatch.SubMatches(1)
        Next
    End With
End Sub

Sub ParseToNestedArr(sPattern, sResponse, arrMatches)
    Dim oMatch, arrSMatches, sSubMatch
    arrMatches = Array()
    With CreateObject("VBScript.RegExp")
        .Global = True
        .MultiLine = True
        .IgnoreCase = True
        .Pattern = sPattern
        For Each oMatch In .Execute(sResponse)
            arrSMatches = Array()
            For Each sSubMatch in oMatch.SubMatches
                PushItem arrSMatches, sSubMatch
            Next
            PushItem arrMatches, arrSMatches
        Next
    End With
End Sub

Sub PushItem(arrList, varItem)
    ReDim Preserve arrList(UBound(arrList) + 1)
    arrList(UBound(arrList)) = varItem
End Sub

Sub XmlHttpRequest(sMethod, sUrl, arrSetHeaders, sFormData, sRespHeaders, sRespText)
    Dim arrHeader
    With CreateObject("Msxml2.ServerXMLHTTP.3.0")
        .SetOption 2, 13056 ' SXH_SERVER_CERT_IGNORE_ALL_SERVER_ERRORS
        .Open sMethod, sUrl, False
        If IsArray(arrSetHeaders) Then
            For Each arrHeader In arrSetHeaders
                .SetRequestHeader arrHeader(0), arrHeader(1)
            Next
        End If
        .Send sFormData
        sRespHeaders = .GetAllResponseHeaders
        sRespText = .ResponseText
    End With
End Sub

它使用后期绑定(bind)，因为初始目标语言是 VBScript，但如果您愿意，将它们更改为早期绑定(bind)并不难。 第二个链接 http://apps.cnbc.com/company/quote/newindex.asp?symbol=SDRL您可以在网页内容中找到 iframe 源。
