Scrape data after clicking on two buttons

Question

I'm trying to scrape the href of each model from this webpage: https://www.aprilia.com/en_EN/index.
The html showing the href data can be seen only after clicking on two buttons (the one on the top right corner and the one on the left called "Models"), one after the other.

Sub get_info()
  
Dim ie As Object
Dim address, str_chk As String
Dim my_data As Object
Dim oHTML_Element As IHTMLElement
Dim i As Long
  
address = "https://www.aprilia.com/en_EN/index"

Set ie = CreateObject("InternetExplorer.Application")
ie.navigate address 'the one mentioned above
ie.Visible = False
  
Do While ie.Busy Or ie.readyState <> 4
    DoEvents
Loop
  
For Each oHTML_Element In ie.document.getElementsByName("button")
    If oHTML_Element.className = "header__menu-services__nav button button--icon" Then
        oHTML_Element.Click
    End If
Next
  
Application.Wait Now + #12:00:05 AM#

For Each oHTML_Element In ie.document.getElementsByName("Models")
    oHTML_Element.Click
Next

Application.Wait Now + #12:00:05 AM#

'==>
Set my_data = html.getElementsByClassName("card-product card-product--family")

For Each elem In my_data
    For i = 0 To elem.getElementsByTagName("a").Length - 1
        str_chk = elem.getElementsByTagName("a")(i).href
        ws.Cells(9 + j, 7).Value = str_chk
        j = j + 1
    Next i
Next elem

ie.Quit
Set ie = Nothing
End Sub

I got

Error '424' - Object Required

where I set my_data.

I guess that means that I'm not able to click on the two buttons and, as a consequence, html code is not available.

***************** Revised code:

Sub get_info22()

Dim address As String
Dim ie, ELE, nodes As Object
Dim i As Long
Dim t As Date
Const MAX_WAIT_SEC As Long = 10
  
address = "https://www.aprilia.com/en_EN/index"

Set ie = CreateObject("InternetExplorer.Application")
ie.navigate address 'the one mentioned above
ie.Visible = False
  
Do While ie.Busy Or ie.readyState <> 4
    DoEvents
Loop

'************** click on first button
t = Timer
Do
    On Error Resume Next
    Set ELE = ie.document.querySelector(".header__menu-services__nav")

    If Timer - t > MAX_WAIT_SEC Then Exit Do
Loop While ELE Is Nothing
If Not ELE Is Nothing Then
    ELE.Click
End If

While ie.Busy Or ie.readyState <> 4: DoEvents: Wend
'************** click on second button
Do
    On Error Resume Next
    Set ELE = ie.document.querySelector("li > button")

    If Timer - t > MAX_WAIT_SEC Then Exit Do
Loop While ELE Is Nothing

If Not ELE Is Nothing Then
    ELE.Click
End If

While ie.Busy Or ie.readyState <> 4: DoEvents: Wend

'************** get href for each model

Set nodes = ie.document.querySelectorAll(".card-product--family")

ReDim hrefs(nodes.Length - 1)

For i = 0 To nodes.Length - 1
    hrefs(i) = nodes.Item(i).href
    ActiveSheet.Cells(9 + i, 7).Value = hrefs(i)
Next

Answer 1

Try first to use more precise selectors. For the first button use:

ie.document.querySelector(".header__menu-services__nav").click

That targets the element by one of its classes. Then have a pause e.g.

While ie.Busy Or ie.ReadyState<>4:DoEvents:Wend

Or, use an explicit wait time or loop until next desired element is present.

Then target the next element with type selectors and child combinator as you want the first child button within a li element:

ie.document.querySelector("li > button").click

Then you need another wait.

Finally, you can use a single class from the target elements, with the links, and extract the href attributes and store in an array (for example)

Dim nodes As Object, hrefs(), i As Long

Set nodes = ie.Document.querySelectorAll(".card-product")

ReDim hrefs(nodes.Length - 1)

For i = 0 To nodes.Length - 1
    hrefs(i) = nodes.Item(i).href
Next

EDIT:

Seems page uses ajax to retrieve the listings which makes this easier. I show to versions. The first where I grab just those links you describe after two button clicks; the second, where I grab model subtype links as well.

In both I mimic the request the page makes to get that info. In the first I then parse the returned json with a json parser and pull out the model links. With the second, I regex out all href info ie. all submodels.

Json library:

I use jsonconverter.bas. Download raw code from here and add to standard module called JsonConverter . You then need to go VBE > Tools > References > Add reference to Microsoft Scripting Runtime. Remove the top Attribute line from the copied code.
