使用VBA将网页数据传输到Excel工作表

这是我的第一篇文章。我是VBA的新手，但我对VB6非常熟悉。我编写了一些代码，将纳斯达克的文本粘贴到工作表中。它终于起作用了。在年度损益表的上方和下方散布着大量无关数据。我想把重要的数据解析出来，放到一个可以自动分析的地方。我想我可以搜索这些单元格，直到找到：年度损益表并提取到另一张表。如有任何建议，将不胜感激。以下是我得到的：

Sub TransferWebData()
Dim IE As Object
Set IE = CreateObject("InternetExplorer.Application")
With IE
    .Visible = True
    .Navigate "http://www.nasdaq.com/symbol/gd/financials" 
    Do Until .ReadyState = 4: DoEvents: Loop
    IE.ExecWB 17, 0 'SelectAll
    IE.ExecWB 12, 2 'Copy selection

    Sheets("GD").Range("A1").Select
    Sheets("GD").PasteSpecial Format:="HTML", Link:=False, DisplayAsIcon:=False, NoHTMLFormatting:=True
    IE.Quit
End With
End Sub

这会让你很忙

将引用设置为Microsoft HTML对象库和Microsoft Internet控件

在GoogleChrome中，我导航到该网页，并使用inspect元素打开WebKit并将xpath复制到该元素。这就给了我一个大致的大纲来起草我的职能。经过一个半小时乏味的调试，我能够将数据提取到数组中

//*[@id=“financials iframe wrap”]/div/table/tbody/tr/td

输出

看看下面的示例，在没有IE自动化的情况下，使用XHR和RegEx检索数据：
