Click all checkboxes on website - excel

Question

I have (in Excel, VBA) a sub that will navigate to this webpage:
http://www.nordea.dk/wemapp/currency/dk/valutaKurser
And copy the quoted rates. However, I would like to remove all the rates, and only add the ones my sub needs.
To do this, I need to check all of the boxes (to the left in the table), but the number of boxes is not constant - so I can't hardcode the boxnames.
I suppose one way to this is to extract the entire html, determine the number of rows, and then loop. But it seems very unhandy. Surely there is some smatter way, which requires less code and less storage?

Answer 1

You can Split() the table by vbNewLine and search for the currency in each row of the set (mind the headers).
Since the inputs are named like table:body:rows:2:cells:1:cell:check you can match the currency with the checkbox.
In practice it looks like (up to getting the element names):
Function FirstRow(myArray() As String, Optional curr As String) As Long
If curr = "" Then
curr = "*[A-Z][A-Z][A-Z]/[A-Z][A-Z][A-Z]*"
Else
curr = "*" & curr & "*"
End If
For i = LBound(myArray) To UBound(myArray)
If myArray(i) Like curr Then 'FX denoted as "XXX/XXX"
FirstRow = i
Exit Function
End If
Next i
End Function
Sub ert()
Dim myArray() As String, URLStr As String
URLStr = "http://www.nordea.dk/wemapp/currency/dk/valutaKurser"
Set ie = CreateObject("InternetExplorer.Application")
ie.Visible = False
ie.Navigate URLStr
Do Until (ie.readyState = 4 And Not ie.Busy)
DoEvents
Loop
On Error GoTo Err:
Data = ie.Document.body.innerHTML 'innerText
If False Then
Err:
Data = ie.Document.body.innerHTML
End If
myArray = Split(Data, "<tr>") 'vbNewLine) 'vbCrLf)
'For i = LBound(myArray) To UBound(myArray)
' Cells(i + 1, 1).Value2 = myArray(i)
'Next
Dim curr() As String
ReDim curr(2)
curr(0) = "DKK/NOK"
curr(1) = "EUR/SEK"
curr(2) = "USD/CHF"
For i = LBound(curr) To UBound(curr)
x = FirstRow(myArray, curr(i)) - FirstRow(myArray) + 1
MsgBox "table:body:rows:" & x & ":cells:1:cell:check"
Next i
ie.Quit
Set ie = Nothing
End Sub
I'm sorry, the vbNewLine won't cut it this time, my bad. Also, checking a named element shouldn't be that hard, had you provided your snipplet for checking all the boxes I would have even given it a shot.
