How to download a table from a web with VBA? - html

Question

I'am trying to download a table from this page
to excel with VBA: http://www.merval.sba.com.ar/Vistas/Cotizaciones/Acciones.aspx --> table "Panel General"
I can download the table "Panel Merval" but i couldn't download the other table.
I use this code for table "Panel Merval":
Sub GetTable()
Dim ieApp As InternetExplorer
Dim ieDoc As Object
Dim ieTable As Object
Dim clip As DataObject
'create a new instance of ie
Set ieApp = New InternetExplorer
'you don’t need this, but it’s good for debugging
ieApp.Visible = False
'now that we’re in, go to the page we want
ieApp.Navigate "http://www.merval.sba.com.ar/Vistas/Cotizaciones/Acciones.aspx"
Do While ieApp.Busy: DoEvents: Loop
Do Until ieApp.ReadyState = READYSTATE_COMPLETE: DoEvents: Loop
'get the table based on the table’s id
Set ieDoc = ieApp.Document
Set ieTable = ieDoc.all.Item("ctl00_ContentCentral_tcAcciones_tpMerval_grdMerval")
'copy the tables html to the clipboard and paste to teh sheet
If Not ieTable Is Nothing Then
Set clip = New DataObject
clip.SetText "" & ieTable.outerHTML & ""
clip.PutInClipboard
Sheet1.Select
Sheet1.Range("b2").Select
Sheet1.PasteSpecial "Unicode Text"
End If
'close 'er up
ieApp.Quit
Set ieApp = Nothing
End Sub
or this one
Public Sub PanelLider()
Dim oDom As Object: Set oDom = CreateObject("htmlFile")
Dim x As Long, y As Long
Dim oRow As Object, oCell As Object
Dim vData As Variant
Dim link As String
link = "http://www.merval.sba.com.ar/Vistas/Cotizaciones/Acciones.aspx"
y = 1: x = 1
With CreateObject("msxml2.xmlhttp")
.Open "GET", link, False
.Send
oDom.body.innerHTML = .ResponseText
End With
With oDom.getElementsByTagName("table")(27)
Dim dataObj As Object
Set dataObj = CreateObject("new:{1C3B4210-F441-11CE-B9EA-00AA006B1A69}")
dataObj.SetText "<table>" & .innerHTML & "</table>"
dataObj.PutInClipboard
End With
Sheets(2).Paste Sheets(2).Cells(1, 1)
End Sub
Could someone help me to download the table "Panel General"?
Many thanks.

Selenium
The following gets the table using selenium basic.
Option Explicit
Public Sub GetTable()
Dim html As New HTMLDocument, htable As HTMLTable, headers()
headers = Array("Especie", "Hora Cotización", "Cierre Anterior", "Precio Apertura", "Precio Máximo", _
"Precio Mínimo", "Último Precio", "Variación Diaria", "Volumen Efectivo ($)", "Volumen Nominal", "Precio Prom. Pon")
With New ChromeDriver
.get "http://www.merval.sba.com.ar/Vistas/Cotizaciones/Acciones.aspx"
.FindElementById("__tab_ctl00_ContentCentral_tcAcciones_tpGeneral").Click
Do
DoEvents
Loop While .FindElementById("ctl00_ContentCentral_tcAcciones_tpGeneral_dgrGeneral", timeout:=7000).Text = vbNullString
html.body.innerHTML = .PageSource
Set htable = html.getElementById("ctl00_ContentCentral_tcAcciones_tpGeneral_dgrGeneral")
WriteTable2 htable, headers, 1, ActiveSheet
.Quit
End With
End Sub
Public Sub WriteTable2(ByVal htable As HTMLTable, ByRef headers As Variant, Optional ByVal startRow As Long = 1, Optional ByVal ws As Worksheet)
If ws Is Nothing Then Set ws = ActiveSheet
Dim tRow As Object, tCell As Object, tr As Object, td As Object, R As Long, c As Long, tBody As Object
R = startRow: c = 1
With ActiveSheet
Set tRow = htable.getElementsByTagName("tr")
For Each tr In tRow
Set tCell = tr.getElementsByTagName("td")
For Each td In tCell
.Cells(R, c).Value = td.innerText
c = c + 1
Next td
R = R + 1: c = 1
Next tr
.Cells(1, 1).Resize(1, UBound(headers) + 1) = headers
End With
End Sub

With IE (Using WriteTable2 sub from above):
Option Explicit
Public Sub GetInfo()
Dim ie As New InternetExplorer, html As HTMLDocument, hTable As HTMLTable, headers(), a As Object
headers = Array("Especie", "Hora Cotización", "Cierre Anterior", "Precio Apertura", "Precio Máximo", _
"Precio Mínimo", "Último Precio", "Variación Diaria", "Volumen Efectivo ($)", "Volumen Nominal", "Precio Prom. Pon")
Application.ScreenUpdating = False
With ie
.Visible = True
.navigate "http://www.merval.sba.com.ar/Vistas/Cotizaciones/Acciones.aspx"
While .Busy Or .readyState < 4: DoEvents: Wend
.document.getElementById("__tab_ctl00_ContentCentral_tcAcciones_tpGeneral").Click
Do
DoEvents
On Error Resume Next
Set hTable = .document.getElementById("ctl00_ContentCentral_tcAcciones_tpGeneral_dgrGeneral")
On Error GoTo 0
Loop While hTable Is Nothing
WriteTable2 hTable, headers, 1, ActiveSheet
.Quit '<== Remember to quit application
Application.ScreenUpdating = True
End With
End Sub
