VBA web scraping issue - how to navigate specific web using html structure (href / child/ )

亲爱的VBA同学您好:)

Sub login()
'test 
    Const URL$ = "https://kwm.kromi.de/cgi-bin/kwm?HTML=frontend/login.htm"
    Dim UserName As String, Password As String, LoginData As Worksheet
    Set LoginData = ThisWorkbook.Worksheets("Sheet1")
    UserName = LoginData.Cells(1, "B").Value
    Password = LoginData.Cells(2, "B").Value
    Dim IE As Object
    Set IE = CreateObject("InternetExplorer.Application")
    With IE
        .Visible = False
        .Navigate URL
        ieBusy IE
        .Visible = True
       Dim oLogin As Object, oPassword As Object
        Set oLogin = .document.getElementsByName("VS_LOGIN")(0)
        Set oPassword = .document.getElementsByName("VS_PASSWORD")(0)
        oLogin.Value = UserName
        oPassword.Value = Password
        .document.forms(0).submit
        ieBusy IE
       Stop
       '.document.getElementsByTagName("a")(2).href
       '.document.getElementsByClassName("link3").Click
     .Navigate2 ""
     ieBusy IE
     Stop
    End With
'''
End Sub
Sub ieBusy(IE As Object)
    Do While IE.Busy Or IE.readyState < 4
        DoEvents
    Loop
End Sub

第一个任务是工作,宏登录网站。我需要更深入地点击一些东西,但是网络结构对我的小脑袋来说太多了我正在网站上查看一些示例,但没有任何效果。我在下面显示了网站代码。我需要点击按钮“statystyka”。

/html/body/div[1]/div[1]/a[2] - Xpath 地址 [link图片]https://ibb.co/2Pgx2tn

请你帮帮我:)

编辑: 我试过使用这样的东西: '.document.getElementsByTagName("a")(2).href 但这不是很好的思考方式

您需要移动到适当的框架,在我使用时添加等待。导航到框架 src,然后您可以通过 onclick 属性的子字符串进行定位:

ie.navigate ie.document.querySelector("[name=Navigator]").src
ieBusy ie
ie.document.querySelector("[onclick*=statistic]").click

如果你想通过标签导航你需要如下设置框架

Dim doc As HTMLDocument
Dim doc2 As HTMLDocument
Dim lnk As HTMLLinkElement

Set doc = IE.document
 Set doc2 = doc.frames("Navigator").document
 Set lnk = doc2.getElementsByTagName("A")(1)
 lnk.Click
