Excel VBA to open the first search result page of google

I have to open the google search page using excel Macro. I am able to successfully open the google search page, after I give my search parameters in excel. However, my task is to open the first returned search result page and do some data extraction in that page. I used the below code.

Suppose if I searched for "Sachin Tendulkar wiki", I should be able to open the first page in the search result. My code so far is as below.

Dim ie As InternetExplorer
Dim RegEx As RegExp, RegMatch As MatchCollection
Dim MyStr As String
Dim pDisp As Object
Set ie = New InternetExplorer
Set RegEx = New RegExp
Dim iedoc As Object

'Search google for "something"
ie.Navigate "http://www.google.com.au/search?hl=en&q=sachin+tendulkar+wiki&meta="

'Loop unitl ie page is fully loaded
Do Until ie.ReadyState = READYSTATE_COMPLETE
Loop



MyStr = ie.Document.body.innertext
Set RegMatch = RegEx.Execute(MyStr)

'If a match to our RegExp searchstring is found then launch this page
If RegMatch.Count > 0 Then
ie.Navigate RegMatch(0)
Do Until ie.ReadyState = READYSTATE_COMPLETE
Loop
MsgBox "Loaded"
'show internet explorer
ie.Visible = True
'Private Sub ie_DocumentComplete(ByVal pDisp As Object, URL As Variant)
Set iedoc = ie.Application.Document
'iedoc.getElementById("divid").Value = "poS0"
'MsgBox iedoc

'ie.Navigate iedoc.getelementsbytagname("ol")(0).Children(0).getelementsbytagname("a")(0).href
ie.Navigate iedoc.getelementsbyclassname("divid")("poS0").href
Else
MsgBox "No linkedin profile found"
End If

Set RegEx = Nothing
Set ie = Nothing


I viewed the page source in the google search page. I have a particular div id = "pos0" which is the id for the first search result. I have to make the IE navigate to the page whose div id = "pos0". I am not able to accomplish this thing in VBA. Can some one please help me out?

Thanks & Regards,

Answer

You have a couple of issues. First to access the document object its ie.Document not ie.Application.Document. I have updated your code to show how the first url can quickly be found using a substring.

Dim ie As InternetExplorer
Dim RegEx As RegExp, RegMatch As MatchCollection
Dim MyStr As String
Dim pDisp As Object
Set ie = New InternetExplorer
Set RegEx = New RegExp
Dim iedoc As Object

'Search google for "something"
ie.Navigate "http://www.google.com.au/search?hl=en&q=sachin+tendulkar+wiki&meta="

'Loop unitl ie page is fully loaded
Do Until ie.ReadyState = READYSTATE_COMPLETE
Loop



MyStr = ie.Document.body.innertext
Set RegMatch = RegEx.Execute(MyStr)

'If a match to our RegExp searchstring is found then launch this page
If RegMatch.Count > 0 Then
    ie.Navigate RegMatch(0)
    Do Until ie.ReadyState = READYSTATE_COMPLETE
    Loop
         MsgBox "Loaded"
         'show internet explorer
    ie.Visible = True
    'Private Sub ie_DocumentComplete(ByVal pDisp As Object, URL As Variant)
    '****************************************
    'EDITS
    '****************************************
    Set iedoc = ie.Document

    'create a variable to hold the text
    Dim extractedHTML As String
    'start and end points for the substring
    Dim iStart, iEnd As Integer
    'get the element with ID of search - this is where the results start
    extractedHTML = iedoc.getElementById("search").innerHTML
    'find the first href as this will be the first link, add 1 to encompass the quote
    iStart = InStr(1, extractedHTML, "href=", vbTextCompare) + Len("href=") + 1
    'locate the next quote as this will be the end of the href
    iEnd = InStr(iStart, extractedHTML, Chr(34), vbTextCompare)
    'extract the text
    extractedHTML = Mid(extractedHTML, iStart, iEnd - iStart)
    'go to the URL
    ie.Navigate extractedHTML

    '****************************************
    'End EDITS
    '****************************************
    Else
    MsgBox "No linkedin profile found"
End If

Set RegEx = Nothing
Set ie = Nothing
