如何使用 vba 从网站表中提取数据

Question

我在编写将从网页中提取数据的代码时遇到问题。 代码的第一部分运行良好，但第二部分我无法正确编写以从站点的表中提取数据。 问题是“td”标签，我需要“td”标签中包含的数据，全部或部分。 我尝试了很多方法，但都没有成功。 任何人都可以帮助我从表中提取这些数据的代码吗？

这是我的代码：

Sub provera_TR_klijenta()

    'check in References: _
    Microsoft Internet Controls _
    Microsoft HTML Object Library
    
    Dim objIE As InternetExplorer 'special object variable representing the IE browser
    Dim aEle As HTMLLinkElement 'special object variable for an <a> (link) element
    
    Dim ieDoc As MSHTML.HTMLDocument
    Dim iframeDoc As MSHTML.HTMLDocument
    
    'initiating a new instance of Internet Explorer and asigning it to objIE
    Set objIE = New InternetExplorer
    
    'make IE browser visible (False would allow IE to run in the background)
    objIE.Visible = True
    objIE.Width = 1000
    objIE.Height = 800
    
    'navigate IE to this web page (a pretty neat search engine really)
    objIE.navigate "https://nbs.rs/en/drugi-nivo-navigacije/servisi/jedinstveni-registar-racuna/index.html"
    'wait here a few seconds while the browser is busy
    Do While objIE.Busy = True Or objIE.readyState <> 4: DoEvents: Loop
    
    Set ieDoc = objIE.document
    Set iframeDoc = ieDoc.frames(0).document
    
    iframeDoc.getElementsByName("matbr")(1).Value = "21122017"
    iframeDoc.getElementsByName("Submit")(0).Click
    
    Do While objIE.Busy = True Or objIE.readyState <> 4: DoEvents: Loop
    
    '*** I don't know what to do from here ***

End Sub
