Trying to extract ONE value from a webpage with VBA in Excel - excel

Question

I've been trying to find the information now for a couple of days, but all the examples I've found just has a small piece of the code, I need it all =)
What I want to do is to extract one value from a homepage and put it into a cell in Excel
(and then take another value from another page on the same site and put in the next cell etc etc.)
The page is a swedish stock-exchange page, and the page I've used as a test-page is the stock for "Investor B" (https://www.avanza.se/aktier/om-aktien.html/5247/investor-b)
And the value I'm interested in is the one called "Senaste" (this is the page-information surrounding it)
<li>
<span class="XSText">Senast<br/></span>
<span class="lastPrice SText bold"><span class="pushBox roundCorners3" title="Senast uppdaterad: 17:29:59">248,60</span></span>
</li>
And it's the value 248,60 I'm after!
I got some coding experience, but not for VBA-scripting, after reading some forum-posts (mostly here), I've been trying out a few example by myself, but couldn't get any to work.
Since I'm quite basic with VBA, I might have got the structure wrong, so please be basic and patient with me, this was my test, but I got "Runtime error 429"
ActiveX component can't create object
I might be totally on the wrong track
Private Sub CommandButton1_Click()
Dim ie As Variant
Set ie = CreateObject("InternetExplorer")
ie.navigate "https://www.avanza.se/aktier/om-aktien.html/5247/investor-b"
ie.Visible = True
Do
DoEvents
Loop Until ie.readyState = READYSTATE_COMPLETE
Application.Wait (Now() + TimeValue("00:00:016")) ' For internal page refresh or loading
Dim doc As Variant 'variable for document or data which need to be extracted out of webpage
Set doc = CreateObject("HTMLDocument")
Set doc = ie.document
Dim dd As Variant
dd = doc.getElementsByClassName("lastPrice SText bold")(0).innerText
MsgBox dd
End Sub
EDIT: 2014-05-12 Current code beeing tested 17:05
under the button command
Private Sub CommandButton1_Click()
Dim IE As Object
' Create InternetExplorer Object
Set IE = CreateObject("InternetExplorer.Application")
' You can uncoment Next line To see form results
IE.Visible = False
' Send the form data To URL As POST binary request
IE.Navigate "https://www.avanza.se/aktier/om-aktien.html/5247/investor-b"
' Statusbar
Application.StatusBar = "Loading, Please wait..."
' Wait while IE loading...
'Do While IE.Busy
' Application.Wait DateAdd("s", 1, Now)
'Loop
'this should go from ready-busy-ready
IEWait IE
Application.StatusBar = "Searching for value. Please wait..."
' Dim Document As HTMLDocument
' Set Document = IE.Document
Dim dd As Variant
dd = IE.Document.getElementsByClassName("lastPrice SText bold")(0).innerText
MsgBox dd
' Show IE
IE.Visible = True
' Clean up
Set IE = Nothing
Set objElement = Nothing
Set objCollection = Nothing
Application.StatusBar = ""
End Sub
And in module1
Public Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
Public Function IEWait(p_ieExp As InternetExplorer)
'this should go from ready-busy-ready
Dim initialReadyState As Integer
initialReadyState = p_ieExp.ReadyState
'wait 250 ms until it's done
Do While p_ieExp.Busy Or p_ieExp.ReadyState <> READYSTATE_COMPLETE
Sleep 250
Loop
End Function
As said earlier, I do not know if I got the structure right with this latest add-in, not to expired in this kind of coding I'm afraid.
Best Regards

Answer 1

You are close but have a couple small errors.
Here is how I would set it up (Tested):
Private Sub CommandButton1_Click()
Dim IE As Object
' Create InternetExplorer Object
Set IE = CreateObject("InternetExplorer.Application")
' You can uncoment Next line To see form results
IE.Visible = False
' URL to get data from
IE.Navigate "https://www.avanza.se/aktier/om-aktien.html/5247/investor-b"
' Statusbar
Application.StatusBar = "Loading, Please wait..."
' Wait while IE loading...
Do While IE.Busy
Application.Wait DateAdd("s", 1, Now)
Loop
Application.StatusBar = "Searching for value. Please wait..."
Dim dd As String
dd = IE.Document.getElementsByClassName("lastPrice SText bold")(0).innerText
MsgBox dd
' Show IE
IE.Visible = True
' Clean up
Set IE = Nothing
Application.StatusBar = ""
End Sub
Results:
Tested in Excel 2010 with the following references:
Edit - Option B
To get rid of a possible "Run-Time Error '91'" try changing a few lines like this:
Dim dd As Variant
Set dd = IE.Document.getElementsByClassName("lastPrice SText bold")
MsgBox dd(0).textContent
Edit - Option C
Yet another way to get elements:
Dim tag
Dim tags As Object
Set tags = IE.Document.getElementsByTagName("*")
For Each tag In tags
If tag.className = "lastPrice SText bold" Then
MsgBox tag.innerText
Exit For
End If
Next tag
(All three methods have been tested on Excel 2010 and IE10)

Answer 2

I just wanted to add the code I'm currently running which works perfectly fine at the moment, if people run into the same problem. This is to get two values into dedicated cells.
Private Sub CommandButton10_Click()
Dim IE As Object
Dim dd As Variant
' Create InternetExplorer Object
Set IE = GetObject("new:{D5E8041D-920F-45e9-B8FB-B1DEB82C6E5E}")
IE.Visible = False
' Send the form data To URL As POST binary request
IE.Navigate "https://www.avanza.se/aktier/om-aktien.html/52476/alk-abell-b"
Application.StatusBar = "Loading, Please wait..."
IEWait IE
Application.StatusBar = "Searching for value. Please wait..."
dd = IE.Document.getElementsByClassName("lastPrice SText bold")(0).innerText
Range("Y2").Value = dd
IE.Navigate "https://www.avanza.se/aktier/om-aktien.html/52380/alm--brand"
Application.StatusBar = "Loading, Please wait..."
IEWait IE
Application.StatusBar = "Searching for value. Please wait..."
dd = IE.Document.getElementsByClassName("lastPrice SText bold")(0).innerText
Range("Y3").Value = dd
' Clean up
Set IE = Nothing
Set objElement = Nothing
Set objCollection = Nothing
Application.StatusBar = ""
End Sub
If one wants more data, it is just to copy the part starting with
IE.Navigate "https://www.pagewhereyourdatayouwanttoextractis.com"
and stops with
Range("Y2").Value = dd
It is ofcourse based if the page you want to extract data from has a similiar structure to the one above.
Hope this can help some people out there.
Best Regards
