我用下面的VBA代碼嘗試，但我得到錯誤強調文本：

Sub scraping() 

    Set ie = CreateObject("InternetExplorer.Application") 
    ie.Visible = False 
    ie.navigate "http:\\website.com" 

    Set elems = ie.Document.getElementsByClassName("highcharts-series highcharts-tracker") 
    Set e = elems.getElementsByTagName("path") 

    k = 1 
    Do Until k = e.Length 
     Cells(k, 5) = e.getAttribute("d") 
     k = k + 1 
    Loop 

End Sub

我做錯了什麼？

「我在*強調的文本*上出現錯誤」 - 什麼錯誤？什麼強調文字？請[編輯]您的帖子澄清。 –

getElementsByClassName返回一組元素（可能包含很多，一個或沒有成員）。

該集合雖然沒有方法getElementsByTagName - 您需要遍歷集合中的元素並在每個元素上調用該方法。

如果您希望只有一個命中，那麼你可以改用：

Set e = elems.getElementsByTagName("path")(0)

您可以用它來讓您的網站的「庫存」。

Sub DumpData() 

Set IE = CreateObject("InternetExplorer.Application") 
IE.Visible = True 

URL = "http://finance.yahoo.com/q?s=sbux&ql=1" 

'Wait for site to fully load 
IE.Navigate2 URL 
Do While IE.Busy = True 
    DoEvents 
Loop 

RowCount = 1 

With Sheets("Sheet1") 
    .Cells.ClearContents 
    RowCount = 1 
    For Each itm In IE.document.all 
     .Range("A" & RowCount) = itm.tagname 
     .Range("B" & RowCount) = itm.ID 
     .Range("C" & RowCount) = itm.classname 
     .Range("D" & RowCount) = Left(itm.innertext, 1024) 

     RowCount = RowCount + 1 
    Next itm 
End With 
End Sub

另外，考慮閱讀一個網站的所有內容到內存中，然後解析出你需要/想要的文本。

Sub Test() 
    Dim IE As Object 

    Set IE = CreateObject("InternetExplorer.Application") 
    With IE 
     .Visible = True 
     .Navigate "http://www.anything.com/" ' should work for any URL 
     Do Until .ReadyState = 4: DoEvents: Loop 

      x = .document.body.innertext 
      x = Replace(x, Chr(10), Chr(13)) 
      x = Split(x, Chr(13)) 

      .Quit 
     End With 

End Sub
