VBA Script pull data from website - vba

Question

I want to pull the data from http://www.buyshedsdirect.co.uk/ to get the most recent prices of specific items.
I have an excel spreadsheet with the following:
|A | B
1 |Item |Price
2 |bfd/garden-structures/arches/premier-arches-pergola
and the VBA script:
Dim ie As New InternetExplorer
Dim item As String
item = Sheet1.Range("A2").Value
Dim doc As HTMLDocument
ie.Visible = True
ie.navigate "http://www.buyshedsdirect.co.uk/" & item
Do
DoEvents
Loop Until ie.readyState = READYSTATE_COMPLETE
Set doc = ie.document
On Error Resume Next
output = doc.getElementByClass("NowValue").innerText
Sheet1.Range("B2").Value = output
ie.Quit
End Sub
i am new to VBA scripting and have no idea why it isnt pulling the value form the class "NowValue"
Any help would be appreciated :)

Answer 1

The On Error Resume Next line is stopping an error message from being displayed. That error message would be that there is no method on HTMLDocument called "getElementByClass". You probably want "getElementsByClassName" instead and will have to handle the fact that this returns a collection rather than a single element. Code like this would work:
Option Explicit
Sub foo()
Dim ie As New InternetExplorer
Dim item As String
item = Sheet1.Range("A2").Value
Dim doc As HTMLDocument
ie.Visible = True
ie.navigate "http://www.buyshedsdirect.co.uk/" & item
Do
DoEvents
Loop Until ie.readyState = READYSTATE_COMPLETE
Set doc = ie.document
Dim results As IHTMLElementCollection
Dim result As IHTMLElement
Dim output As String
Set results = doc.getElementsByClassName("NowValue")
output = ""
For Each result In results
output = output & result.innerText
Next result
Sheet1.Range("B2").Value = output
ie.Quit
End Sub
You would then find that there are multiple elements with class "NowValue" on that page. It looks as though the one you want might be enclosed in a div called "VariantPrice" so this code should work:
Option Explicit
Sub bar()
Dim ie As New InternetExplorer
Dim item As String
item = Sheet1.Range("A2").Value
Dim doc As HTMLDocument
ie.Visible = True
ie.navigate "http://www.buyshedsdirect.co.uk/" & item
Do
DoEvents
Loop Until ie.readyState = READYSTATE_COMPLETE
Set doc = ie.document
Dim results As IHTMLElementCollection
Dim results2 As IHTMLElementCollection
Dim result As IHTMLElement
Dim result2 As IHTMLElement
Dim output As String
Set results = doc.getElementsByClassName("VariantPrice")
output = ""
For Each result In results
Set results2 = result.getElementsByClassName("NowValue")
For Each result2 In results2
output = output & result2.innerText
Next result2
Next result
Sheet1.Range("B2").Value = output
ie.Quit
End Sub
edit: as the code above works perfectly for me but fails to work for the question asker, it may be the case that they are using an older version of Internet Explorer which does not support getElementsByClassName. It may be the case that using querySelector will work instead. To be certain, go to this QuirksMode page to determine exactly what your browser supports.
New code using querySelector:
Option Explicit
Sub bar()
Dim ie As New InternetExplorer
Dim doc As HTMLDocument
Dim result As IHTMLElement
Dim result2 As IHTMLElement
Dim item As String
item = Sheet1.Range("A2").Value
ie.Visible = True
ie.navigate "http://www.buyshedsdirect.co.uk/" & item
Do
DoEvents
Loop Until ie.readyState = READYSTATE_COMPLETE
Set doc = ie.document
Set result = doc.querySelector(".VariantPrice")
Set result2 = result.querySelector(".NowValue")
Sheet1.Range("B2").Value = result2.innerText
ie.Quit
End Sub
further edit: to make the macro loop through all of the entries in column A, here are the relevant bits to add or change:
Option Explicit
Sub bar()
Dim ie As New InternetExplorer
Dim doc As HTMLDocument
Dim result As IHTMLElement
Dim result2 As IHTMLElement
Dim item As String
Dim lRow As Long
ie.Visible = True
lRow = 2
item = Sheet1.Range("A" & lRow).Value
Do Until item = ""
ie.navigate "http://www.buyshedsdirect.co.uk/" & item
Do
DoEvents
Loop Until ie.readyState = READYSTATE_COMPLETE
Set doc = ie.document
Set result = doc.querySelector(".VariantPrice")
Set result2 = result.querySelector(".NowValue")
Sheet1.Range("B" & lRow).Value = result2.innerText
lRow = lRow + 1
item = Sheet1.Range("A" & lRow).Value
Loop
ie.Quit
End Sub
