Question

整个代码试图使用VBA从Yahoo Finance获取历史数据。一切都很好，除了代码，我试图从雅虎网站获取公司的名称。

这第一段代码只是为了说明变量或其他内容中的定义没有错误。

Enum READYSTATE
READYSTATE_UNINITIALIZED = 0
READYSTATE_LOADING = 1
READYSTATE_LOADED = 2
READYSTATE_INTERACTIVE = 3
READYSTATE_COMPLETE = 4
End Enum

Sub GetData()
    Dim datasheet As Worksheet
    Dim EndDate As Date
    Dim StartDate As Date
    Dim symbol As String
    Dim qurl As String
    Dim nQuery As Name
    Dim LastRow As Integer
    Dim ohtml As HTMLText

On Error GoTo error_getdata

    Application.ScreenUpdating = False
    Application.DisplayAlerts = False
    Application.Calculation = xlCalculationManual
    Set datasheet = ActiveSheet

    StartDate = datasheet.Range("startDate").Value
    EndDate = datasheet.Range("endDate").Value
    symbol = datasheet.Range("ticker").Value
    symbol = UCase(symbol)

    'Download data from Yahoo Finance'
    Sheets("Home").Activate
    Sheets(symbol).Range("a1").CurrentRegion.ClearContents

    qurl = "http://ichart.finance.yahoo.com/table.csv?s=" & symbol
    qurl = qurl & "&a=" & Month(StartDate) - 1 & "&b=" & Day(StartDate) & _
            "&c=" & Year(StartDate) & "&d=" & Month(EndDate) - 1 & "&e=" & _
            Day(EndDate) & "&f=" & Year(EndDate) & "&g=" & Sheets(symbol).Range("a1") & "&q=q&y=0&z=" & _
            symbol & "&x=.csv"
    eurl = "https://finance.yahoo.com/quote/" & symbol & "?ltr=2"

这里是问题所在。我试图废弃该网站的html，寻找该公司的名称。如果我查看网站的html代码，我会发现该公司的名称标记为 reactid =＆＃34; 239＆＃34; 。我想我要做的就是使用 getelementsbyID（＆＃34; 239＆＃34;），但我不确定。

   '''''
Dim objIe As Object

Set objIe = CreateObject("InternetExplorer.Application")
objIe.Visible = False
objIe.navigate eurl
    Application.StatusBar = "Looking for information in Yahoo Finance"
While (objIe.Busy Or objIe.READYSTATE <> 4): DoEvents: Wend
Set xobj = objIe.querySelectorAll("[reactid=239]")
Debug.Print xobj.innerText
Set xobj = Nothing
objIe.Quit
Set objIe = Nothing
Application.StatusBar = ""

'Sort the existence of a ticker in our sheet and create a new one ' 
    Dim worksh As Integer
    Dim worksheetexists As Boolean
    Dim x As Integer
    worksh = Application.Sheets.Count
    worksheetexists = False
    For x = 1 To worksh
        If Worksheets(x).Name = symbol Then
            worksheetexists = True
            Sheets(symbol).Delete
            ActiveWorkbook.Sheets.Add(after:=Worksheets(Worksheets.Count)).Name = symbol
            Exit For
        End If
    Next x
    If worksheetexists = False Then
        ActiveWorkbook.Sheets.Add(after:=Worksheets(Worksheets.Count)).Name = symbol
    End If

' Load data '
QueryQuote:
    With Sheets(symbol).QueryTables.Add(Connection:="URL;" & qurl, Destination:=Sheets(symbol).Range("a1"))
      .BackgroundQuery = True
      .TablesOnlyFromHTML = False
      .Refresh BackgroundQuery:=False
      .SaveData = True
    End With

    Sheets(symbol).Range("a1").CurrentRegion.TextToColumns Destination:=Sheets(symbol).Range("a1"), DataType:=xlDelimited, _
                TextQualifier:=xlDoubleQuote, ConsecutiveDelimiter:=False, Tab:=True, _
                Semicolon:=False, Comma:=True, Space:=False, other:=False

    Sheets(symbol).Columns("A:G").ColumnWidth = 12

    'Sort data'
    LastRow = Sheets(symbol).UsedRange.Row - 2 + Sheets(symbol).UsedRange.Rows.Count

    Sheets(symbol).Sort.SortFields.Add Key:=Range("A2"), _
        SortOn:=xlSortOnValues, Order:=xlAscending, DataOption:=xlSortNormal
    With Sheets(symbol).Sort
        .SetRange Range("A1:G" & LastRow)
        .Header = xlYes
        .MatchCase = False
        .Orientation = xlTopToBottom
        .SortMethod = xlPinYin
        .Apply
        .SortFields.Clear
    End With
Exit Sub

error_getdata:
    MsgBox ("Fatal error. Please insert a valid sticker for the stock")  
End Sub

我注意到这不是获得我想要的最有效方式。首先，我想学习如何完成它，然后我将承担该计划的效率。

编辑：使用一些答案，我编辑了一下代码，它仍然显示错误（错误438）：

Set xobj = objIe.querySelectorAll("[reactid=239]")

Answer 1

我会考虑使用http://www.w3schools.com/jsref/met_document_queryselectorall.asp

可以允许使用CSS选择器语法选择节点，并且http://www.w3schools.com/cssref/css_selectors.asp

提供了此语法的参考

所以也许就像

那样

document.querySelectorAll("[reactid=239]")

顺便提一下，如果您使用工具参考

，则可以浏览库

Microsoft HTML Object Library
